Objective: To prevent the intercepting pump station of the first-stage combined sewage treatment project from discharging sewage into Suzhou River during the pump start-up and maintenance in dry season, and to eliminate the pollution load that unnecessarily enters Suzhou River.
Main environmental problems: starting the operation system of the pumping station before regular commissioning and sedimentation leads to the pumping station discharging a large amount of sewage into Suzhou River.
Expected effect: Ensure that no waste sewage is discharged into Suzhou River during regular trial operation. Pumping stations are not allowed to drain into Suzhou River during dry season, and try not to drain water during light rain. Therefore, the COD pollution load of Suzhou Creek is reduced to about 12 tons/day.
Investment cost: 31120,000 yuan.
Project Description: Install a gate on the rainwater outlet pipe leading to Suzhou River, and lay a return pipe to make the directly discharged sewage return to the intercepting pipe or the intake pool of the pumping station. The project involves Gubei, China Normal University, Lin Jiaxiang, Caojiaxiang, Fuxing Village, Huayang, Yichuan (West), Kangding, Huasheng, Tibet (North), Jiangxi (Middle), Fujian (North), Zhapu, New Railway Station, Dongxin Village, Zhao Guang 17 intercepting pumping stations.

(Huacao Port ~ Danba Road) Sewage Interception Project of Directly Discharging Suzhou River
Objective: To intercept the pollution sources directly discharged into the main stream of Suzhou River and block the sewage outlets of enterprises and institutions along the river by using the first-stage comprehensive sewage treatment project. Twenty-eight enterprises and institutions along the Suzhou River from Danba Road to the west of Gubei Road to Huacao directly discharged sewage from Suzhou River, municipal pipelines and municipal pumping stations, and the section from Huacao Port to Danba was included in the first phase of comprehensive sewage treatment project, thus reducing the pollution load in the upper reaches of Suzhou River.
Main environmental problems: After the operation of the first phase of combined sewage treatment project, the pollution load of point sources and pumping stations directly discharged from the west of Gubei Road and Danba Road to the main stream of Huacao section into Suzhou River is still relatively large, which is one of the important reasons for the deterioration of water quality in Suzhou River.
Expected effect: According to preliminary calculation, the implementation of this scheme can reduce the sewage volume of Suzhou River from Huacao Port to Danba Road by about 22,400 cubic meters per day.
Investment cost:19.26 million yuan.
. Project description:
There are six units in the north bank of Suzhou Creek, including Shanghai Hart Toys Co., Ltd., and the sewage volume is about 197 cubic meters per day. The district environmental protection department urged six units to treat their sewage on the spot and discharge it into nearby water bodies after reaching the discharge standard.
South bank of Suzhou River: There are 22 units such as Tianyuan Chemical Plant and 2 municipal drainage pumping stations such as Furong River Pumping Station, with a sewage volume of about 22,400 cubic meters per day. The sewage interception plan is as follows:
Labor Steel Pipe Factory-Changjiang Road Pumping Station Section: Dredge and dredge the φ 600 ~ φ 1200 sewage pipe of No.8 branch line of the original west trunk line to restore its water flow capacity. After the sewage of 16 units along the line is intercepted, it will be sent to the drainage system of the first phase of combined sewage treatment by Changning Road Pumping Station.
Huacao Port-Labor Steel Pipe Factory Section: According to the sewage interception project of Suzhou River tributary, φ 1200 pipeline is laid, and it enters the main pipeline of the south line of Bailong Port sewage discharge system from north to south along the outer ring road. Recently, it was temporarily connected with the original No.8 branch line of the west trunk line and connected to the primary discharge system of combined sewage treatment.
Furonghe Pumping Station will be equipped with intercepting facilities, and the sewage will be intercepted to Tianshan Sewage Treatment Plant.
This plan is required to be completed within 1998.
Branch canal sewage interception project
Objective: To reduce the pollution load of six main tributaries of Suzhou River (Pengyuepu, Zhenru Port, Mudu Port, xin jing Port, Jishen Port and Huacao Port) and improve the water environment quality of the tributaries.
Main environmental problems: the water pollution of the six main tributaries of Suzhou River is more serious than that of the main stream of Suzhou River. After the first phase of the combined sewage interception project was put into operation, the pollution load imported from these tributaries accounted for a considerable proportion. In addition, in the long run, the water environment quality of tributaries also needs to be improved.
Expected effect: The planned sewage volume of tributary sewage interception project is about 400,000 cubic meters/day. The CODCr load of Suzhou Creek can be reduced by about 40 tons/day.
Investment cost: 6.05 billion yuan.
Project outline: The planned tributary sewage interception project will build sewage interception pipelines in the north and south of Suzhou respectively. Nanmin Road sewage main pipe and Xincun Road sewage main pipe were laid in the Hebei section of Suzhou, and 272,300 cubic meters/day sewage was brought into the west trunk line of the existing sewage interception system. The main sewage pipeline of Minaminooooji extends eastward along Minaminooooji (from the entrance of Hu Jia Expressway) to the west trunk line, and the sewage is pumped into the west trunk line through the pumping station. The sewage along Jiangqiao and Zhongchapu is fed into the sewage main pipe of Minaminoooji through the sewage branch pipe planned to be laid on the outer ring road. Minaminoooji sewage pipe has a service area of 22 square kilometers and receives a total of 202,300 cubic meters of sewage every day. The main sewage pipe of Xincun Road runs from the south side of Wenshui Road to Zhennan Road, and turns eastward along Zhennan Road and Xincun Road to the existing pumping station of Xincun Road on the west trunk line. The service area of Xincun Road sewage pipe is 7.5 square kilometers, and the daily sewage intake is 70,000 cubic meters. Suzhou Henan tributary interception system has a service range of 33 square kilometers; The sewage receiving capacity is 6.5438+0.35 million cubic meters/day. Sewage pipes are planned to be laid along Wudai Road, Beizhai Road, Hongmei Road and Wuzhong Road in the south and connected with the planned outer ring sewage pipe. In the near future, it is planned to connect the southern135,000 cubic meters/day sewage to the main sewage interception pipe in Wu Min; Long-term planning is included in the south trunk line of the second phase of sewage treatment project. It is planned to build a centralized sewage treatment plant outside the service area of tributary sewage interception system, and the treated wastewater will enter the interception system through branch pipes or be discharged to suitable surface water bodies.
The construction plan of tributary sewage interception system started from 1998 and was fully completed in 2005.
The purpose of this project is to control and reduce the pollution load of seven tributaries of Suzhou River (Mudu Port, Xishahe River, Xiaofengbang, Laofengbang, Huangqiao Port, Beizhoujing and Gugangjing) on the main stream of Suzhou River.
Main environmental problems: The water pollution in seven tributaries of Suzhou River is more serious than that in the main stream of Suzhou River. After the first phase of the combined sewage interception project is put into operation, the pollution load from these tributaries still accounts for a considerable proportion.
Expected effect: It is estimated that after the completion of the tributary, the CODCr load of the tributary entering Suzhou River will be reduced by about 75 tons/day.
Investment cost:186.32 million yuan.
Project Description: Among the six main tributaries in Suzhou Creek City, only Mudu Port has not crossed the gate. In addition, there are six tributaries in the upstream that have not been opened. If these seven tributaries are also built to prevent pollution, then the tributaries will only drain Suzhou River in flood season or rainstorm period, and the pollutant concentration will be diluted at this time, so the pollution impact on Suzhou River water quality is relatively light. It is planned to complete the construction of six sluices and one set of sluices in Mudu Port and its six upstream tributaries in 1998.
The project is scheduled to be completed by the end of 1998.
The scheme mainly adopts fixed artificial aeration reoxygenation system, which is dynamically and automatically controlled by computer system according to water level, flow rate, tide and dissolved oxygen concentration in water. Artificial reoxygenation was carried out in the river section with the greatest anoxia below Huacao and above Changshou Road Bridge. Fixed aeration system can build a new landscape of Suzhou River.
The project is scheduled to be completed in 2005. Comprehensive water transfer project
Objective: To increase the flow of Suzhou Creek, increase the transport capacity of the river, speed up the flow rate, activate the water body, improve the renewal speed of the water body, reduce the residence time of the sewage group in the river and restore the ecological function.
Main environmental problems: the net discharge of Suzhou River is small, and the tidal action makes the sewage mass reverberate in the river.
Expected effect: fresh water diversion is beneficial to improve the water quality of Suzhou River in a short time.
Investment cost: 1.227 million yuan.
. Project description:
The first phase of the comprehensive water transfer project plans to build a water transfer pump with a flow of 60 seconds cubic meters at the mouth of Suzhou River, and at the same time build a two-way water retaining gate; A water transfer pumping station will be built at Donggaojing in Pubei section of Peng Yue and at the mouth of Taopu River north, with a total installed capacity of 60 seconds cubic meters; Water transfer pumping stations were built in Dongdaying and Xiaoqing Longgang in the upper reaches of Suzhou River, with an installed capacity of 60 seconds cubic meters. Through the reasonable dispatching of sluice pumps, the Huangpu River flood and the water from the upper reaches of Suzhou River are fully utilized, and the Suzhou River is discharged into Yunzaobang to the Yangtze River estuary through the operation of Taopu River and Pengyuepu Hedong Gaojing Pumping Station, so as to achieve the purpose of frequent replacement of Suzhou River.
The second phase of comprehensive water transfer project plans to widen the bottleneck section of Suzhou River upstream 16km, and widen the dredging section of Taopu River and Pengyuepu River East Gaojing River to improve water transfer capacity.
The project will be completed before 2005.
Sewage interception project of Hongkou port and Yangpu port
Objective: Through the implementation of the project, reduce the total amount of sewage from Hongkou Port and Yangpu Port entering Suzhou River through Yujingpu.
Main environmental problems: the total area of the two port basins is 2 1.58 square kilometers, and the total service population is 840,000. At present, it receives nearly 800 thousand tons of sewage every day, and the water body is black and smelly all the year round, and the water quality index exceeds the national standard of surface water by about 1.20 times. Sewage from "two ports" is discharged into Suzhou River through Yujingpu (a tributary of Suzhou River downtown section).
Expected effect: The dry sewage in the basin system of Hongkou Port and Yangpu Port will be incorporated into the main sewage pipe of the first-phase combined sewage treatment project and the main sewage pipe of the northern line project of the second-phase combined sewage treatment project in the long term by using the surplus capacity of the main pipe in the non-rainy season. Through the implementation of the project, the total amount of sewage entering Suzhou River will be reduced.
Investment cost:1089190,000 yuan.
Project content: According to the sewage planning of Shanghai, the dry sewage of Hongkou Port and Yangpu Port will be included in the north trunk of the second phase of sewage treatment project. Considering that the northern line project can't be completed before 2000, it is planned to use the surplus capacity of the combined sewage treatment phase I project in the dry season (the total flow of the main pipe in the first phase is 44.9 m3/s in rainy days, the peak value in the dry season is 2 1.06 m3/s, and the surplus capacity in the dry season is at least 23.84 m3/s) to accept the low-flow sewage from Hongkou and Yangpu river basin systems, thus reducing the number of sewage.
The project is scheduled to start in 2000 and be completed in 2005.
Hongkou Port Water System Reconstruction Project
Objective: To control the highest water level of Hongkou Port water system and ensure the safety of urban flood control and drainage. Accelerate the renewal of water bodies and improve the self-purification ability of river networks.
Main environmental problems: Hongkou Port water system receives wastewater from dozens of factories and domestic sewage from millions of people. The water body is black and smelly all the year round, and the water quality is worse than the V water environmental standard. Rivers are generally silted up, and sewage and dirt are discharged into Huangpu River with the tide, which worsens the water quality of Huangpu River and increases the pollution load of Suzhou River passing through Yujingpu.
Expected results: By dredging the river course of Hongkou Port, on the basis of simultaneous implementation of the sewage interception project of Hongkou Port, Huangpu River water was introduced to improve the water storage and delivery capacity of Hongkou Port water system, and the disrepair flood control walls on both sides of the river course were rebuilt, so as to effectively control the highest water level of the river network, ensure the safety of urban flood control and drainage, and improve the self-purification capacity of the river network, which has a remarkable effect on eliminating the serious black odor phenomenon of Hongkou Port water system all the year round.
Investment cost: RMB 665,438+0,565,438+0.6 million.
Project outline: In order to meet the requirements of regional flood control and drainage safety and water resources dispatching, it is planned to dredge rivers, build flood control walls, and build three new pumping stations, namely Qiaohao Port, Xisitang Port and Hongkou Port, with a total installed capacity of 70 cubic meters per second. In order to prevent the rainwater and sewage received by Xiaojipu from invading the water system of Hongkou Port, and to facilitate the water resources dispatching in non-drainage period, a 4×4 m box culvert was built at the north and south ends of Xiaojipu. At the same time, three gates were newly built and rebuilt to meet the requirements of frequent opening and closing of gates. Carry out comprehensive improvement and greening construction on both sides of Hongkou Port water system.
The project is scheduled to start in 2000 and be completed in 2005.
Shidongkou Municipal Sewage Treatment Plant Project
Objective: To prevent the urban primary sewage transported by the west trunk line of sewage from being discharged to the vicinity of the Yangtze River estuary, so as not to cause serious pollution to the water environment of the Yangtze River.
Main environmental problems: West trunk line 197 1 year is completed and put into operation, with a designed sewage transport capacity of 700,000 cubic meters per day. Untreated, it was discharged into the Yangtze River at Shidongkou, Shengqiao Town, Baoshan District, which has seriously polluted the coastal environment for decades.
Expected results: On the one hand, the implementation of the large-scale sewage treatment plant in Shidongkou can effectively treat the sewage originally discharged into the west trunk line, meet the discharge standards and improve the water environment along the river in Shidongkou. On the other hand, it also provides a good basic condition for the expansion of the west trunk line, and solves the sewage outfall of the Suzhou River tributary interception project and the sewage outfall of Baoshan District, Jiading District and other urbanized areas.
Investment cost: 1.264 1.5 million yuan.
Project Description: 1993 After the first phase of comprehensive sewage treatment project was completed and put into use, most of the sewage originally belonging to the west trunk service area was included in the first phase of comprehensive sewage treatment project. At present, the actual water volume of the west trunk line is15 ~ 200,000 cubic meters/day. According to the sewage planning of Shanghai, with the development of Suzhou Creek comprehensive environmental improvement project, the service scope of the west trunk line will be adjusted: the sewage from Jiading, Nanxiang and the northwest of the city, as well as a large amount of primary sewage in the process of Suzhou Creek comprehensive environmental improvement, will be included in the west trunk line sewage trunk line, and the planned sewage volume within the service scope of the west trunk line will increase to 6,543,800 tons/day in 2020. Such a large amount of primary sewage discharged directly into the coastal area will have a worse impact on the Yangtze River.
The planned sewage treatment capacity of this project is 6.5438+600,000 m3/day, and the planned sewage treatment capacity of the first phase project (by 2005) is 400,000 m3/day. AOO process of two-stage biological treatment for phosphorus and nitrogen removal is adopted, and the sewage is discharged nearby after biological treatment reaches the effluent quality standard. Sludge treatment adopts two-stage medium-temperature digestion, concentration and dehydration processes.
The first phase of Shidongkou Sewage Treatment Plant is scheduled to start on 1998 and put into use in 2005.
Sediment dredging and disposal project
Objective: To reduce the influence of oxygen consumption of sediment on water quality and the pollution caused by sediment resuspension.
Main environmental problems: the re-suspension of sediment is one of the important reasons for the black odor of Suzhou River. In addition, the oxygen consumption of sediments also aggravated the process of water quality deterioration.
Expected effect: It is estimated that the CODcr load into Suzhou river bottom mud can be reduced by 20 tons/day, BOD5 by 8 tons/day and NH3-N by 5 tons/day.
Investment cost: 270.27 million yuan.
Project description: Suzhou river bottom mud is dominated by organic pollution and has obvious sequence structure. Although the content of heavy metals in sediments did not reach the standard of dredged sediments formulated by the Netherlands, it was generally higher than the soil background value. In the heavily polluted reaches of urban areas, the content of heavy metals in sediments has exceeded the biological concentration level stipulated by Canada. It is estimated that the oxygen consumption rate and rate of sediments are related to the content and type of organic matter in sediments. The floating mud on the surface of Suzhou River is rich in organic matter, which will consume a lot of dissolved oxygen in the water during the degradation process, and will be resuspended with a little stirring, making the river black; The sediment has high content of heavy metals, complex components, obvious odor and serious organic pollution. Organic matter degrades under anaerobic conditions, and malodorous gases such as mercaptan and hydrogen sulfide produced in the process of degradation are released into water. This project will be combined with waterway dredging to remove river sediment. Small dredgers can be considered to dredge river sediment in different river sections or hydraulic dredging. Effective disposal and waste utilization of dredged sediment to avoid secondary pollution.
The project is scheduled to start in 2000 and be completed in 20 10.
River aeration reoxygenation project
Objective: To improve the concentration of dissolved oxygen in water and accelerate the recovery of benign circulation of river ecosystem.
The main environmental problems: the Suzhou River is seriously polluted by organic matter, and the dissolved oxygen concentration is extremely low, which has become a limiting factor for the self-purification ability of the water body.
Expected effect: Through aeration and reoxygenation, the dissolved oxygen in the water body is obviously increased, the water quality of Suzhou River is accelerated, and the self-purification ability of Suzhou River is restored, creating necessary conditions for the survival of fish.
Investment cost:187.24 million yuan.
. Project description:
In the process of water and wastewater treatment, aeration and oxygenation biodegradation are widely used. If the dissolved oxygen in Suzhou Creek is restored to above 3 mg/L, the aerobic biodegradation process in the water can be carried out normally, and the black odor phenomenon can be eliminated, which is beneficial to the gradual recovery of the aquatic ecosystem. In summer, the biodegradation in water body is enhanced, the consumption of dissolved oxygen is also obviously increased, and the natural reoxygenation process of water body is weakened, so the lack of oxygen is greater. In this case, the effect of artificial oxygenation can be fully reflected. During the Asian Games in Beijing, the rivers near the Asian Games Village in China were oxygenated, and the water quality was obviously improved. The Delaware River in the United States, the Thames River in the United Kingdom and Osaka City in Japan all have successful experiences in river aeration.
The scheme mainly adopts fixed artificial aeration reoxygenation system, which is dynamically and automatically controlled by computer system according to water level, flow rate, tide and dissolved oxygen concentration in water. Artificial reoxygenation was carried out in the river section with the greatest anoxia below Huacao and above Changshou Road Bridge. Fixed aeration system can build a new landscape of Suzhou River.
The project is scheduled to be completed in 2005. Suzhou river water surface cleaning project. Objective: To take comprehensive cleaning measures to reduce the pollution of Suzhou River and improve its image. Main environmental problems: At present, the surface of Suzhou River is filthy, with a lot of garbage, sundries and oil slick floating, which seriously pollutes the river. Expected effect: The amount of garbage and sundries entering Suzhou River is obviously reduced, and the river surface is basically kept clean. Investment cost: 30.3 million yuan. Project description:. Implement the "responsibility system management in front of the door" measures, establish a four-level management system of city, district, street and residence, set up a full-time supervision and law enforcement team, strengthen the inspection, supervision and law enforcement of the "responsibility system in front of the door", and urge coastal units to implement the cleaning responsibility stipulated in the "responsibility system in front of the door" to ensure that the sanitation compliance rate along the Suzhou Creek is above 95%. Strengthen health supervision and law enforcement. Equipped with law enforcement management vehicles, it is necessary to equip 4 surveillance boats, 20 motorcycles and 10 surveillance law enforcement vehicles, increase the frequency of inspections and strictly punish violations. Increase the number of ships and facilities to clean up the water surface, add 4 ships in Suzhou River, equip 9 catamarans, put 20 garbage collection rafts, add 4 ships to collect ship garbage and excrement, 3 ships patrol to salvage the water surface garbage, 6 cleaning ships (including 2 imported ships) and 4 monitoring and law enforcement ships. Planned1completed by the end of 1998. Relocation project of sanitation wharf. Objective: To avoid the pollution of Suzhou Creek caused by sanitation dock during the garbage and excrement transfer operation, ensure that the garbage and excrement produced in some areas on both sides of Suzhou Creek are cleaned and disposed in time, and improve the Suzhou Creek landscape. Main environmental problems: The sanitation wharf along the Suzhou Creek polluted the water quality of Suzhou Creek in the process of transferring garbage and feces, which seriously affected the landscape of Suzhou Creek. Expected results: The situation of garbage and feces scattered on Suzhou River has been eliminated, and the garbage and feces produced in some areas on both sides of Suzhou River can be removed in time and treated scientifically with modern technology, and the landscape on both sides of Suzhou River has been obviously improved. Investment cost: 210.35 billion yuan. Project description:. Distribution of Suzhou Creek Sanitation Wharf.
Suzhou River Sanitation Wharf is used to transport urban garbage to Nanhui Laogang and Chuanshajiang Town. Transfer the feces to suburban rural areas or discharge them through the south and west sewage trunk lines. There are 16 garbage and feces docks along the Suzhou Creek, which can load and unload about 3,200 tons of domestic garbage and 2,300 tons of feces every day. See table 6. 1 for distribution and operation. It is understood that the actual utilization rate of existing garbage and manure terminals is low, and the number of terminals may be greatly reduced through merger.
. Project construction content
. 1997- 1998 completed the relocation of sanitation wharf and auxiliary wharf east of Suzhou Creek changshou road Bridge in the first half of the year.
Before 2005, complete the relocation of all garbage, feces docks and auxiliary docks along the Suzhou River.
Construction of Domestic Waste Incineration Plant
The construction planning and site selection of waste incineration plant is located in Jiangqiao Town, Jiading District or Liuxing Town, Baoshan District, covering an area of about 200 mu. The final design scale of the incineration plant is set at 4,000 tons/day, and it is planned to be implemented in two phases: the design scale of the first phase project is initially set at about 2,000 tons/day, and it is expected to be completed in 1999; The design scale of the second phase of the project is also 2000 tons/day, which can accept the domestic waste treatment in Putuo and Changning District, and is expected to be completed in 2005.
Supporting the construction of garbage compression transfer station
After the relocation of the garbage wharf along Suzhou Creek, the domestic garbage in Huangpu, Zhabei, Jing 'an, Putuo and Changning districts will be transported to the garbage treatment plant by fully enclosed large vehicles, and the garbage will be compressed and loaded at the transfer stations in each district before being transported. It is planned to build four garbage compression transfer stations.
Increase sanitation vehicles and expand parking lots.
Due to the increase of garbage transportation distance in the above five areas, it is necessary to increase vehicles and other equipment and parking lots accordingly. It is planned to expand or build five parking lots for sanitation vehicles, each of which covers an area of 10- 16 mu.
Construction of fecal discharge station
The ultimate way out for urban manure is to bring it into urban sewage treatment facilities through urban sewage main pipes. Huangpu, Zhabei, Jing 'an, Putuo and Changning are all located in the service scope of the first phase of the combined sewage treatment project. After the relocation of the manure wharf, domestic sewage such as manure will be included in the combined sewage pipeline. In the area where the main pipeline of the first phase of the combined sewage treatment project passes, it is planned to build two 700 cubic meters/day excrement discharge stations. In the transitional stage, in some areas that do not have the conditions to receive sewage temporarily, the feces will be pumped and discharged by the sanitation department, transported by vehicles to the nearest urban sewage plant for treatment, or transported to the nearest combined sewage pumping station, and discharged into the combined sewage main pipe after solid-liquid separation.
The construction period of this project is 1997 to 2005. Freight station relocation project. Objective: According to the requirements of Suzhou Creek's functional orientation, the freight function of greening section should be gradually abolished, and the freight function of greening extension section should be restricted, so as to reduce the pollution load of freight sundries on Suzhou Creek and improve the landscape value of Suzhou Creek. Main environmental problems: The cargo terminals along the Suzhou River polluted the water quality of the Suzhou River in the process of loading and unloading groceries, which seriously affected the landscape of the Suzhou River. Expected results: Through the five measures of demolition, merger, retention, reconstruction and new construction, the freight terminals east of Changshou Road and Bridge are all demolished, and all kinds of management terminals are re-planned, thus the sanitary conditions and landscape value along the coast are obviously improved. Investment cost: 654.38+600,000 yuan. Description of the project. Distribution status of coastal docks in the east section of Changshou Road and Bridge. The middle line of Suzhou Creek in the eastern section is 4980 meters long and the coastline is 9960 meters long, which is the location where freight terminals are concentrated. The docks between Sichuan Luqiao and Huangpu River have all been relocated. The existing docks are mainly distributed between Changshou Road Bridge and Sichuan Road Bridge. There are 20 North Shore Wharfs, involving 1 1 set, with an annual throughput of about1550,000 tons. There are 24 wharves on the south bank, involving 14, with an annual throughput of about1.2000 tons. At present, the loading and unloading capacity of the docks along Suzhou Creek is very low, and professional loading and unloading units can load and unload the same goods only by their 1/4- 1/3 coastline. Suzhou Creek Wharf can be reorganized by merging the docks with low utilization rate. For example, poultry and egg companies, vegetable companies and fruit companies all have unnecessary dock facilities on the Suzhou River. This kind of wharf will be cancelled. In view of the fact that the shipping function of the downstream of Huacao River in Suzhou Creek will gradually shrink, the tonnage of berthing ships at Suzhou Creek Wharf is less than100t, and the relocation plan of the freight terminal is divided into three steps. 1998 All freight stations east of changshou road were relocated in the first half of the year. . 1999 ~ 2000, complete the relocation, merger, reconstruction and construction of the management wharf in the urban section. From 200 1 to 20 10, about 70 road loading and unloading points, heavy pollution loading and unloading points and freight stations that do not meet the reserved conditions will be dismantled or stopped.
Urban cross-strait reconstruction project. Objective: To increase the green area along Suzhou Creek and improve the environmental quality. Control the perennial water level of Suzhou Creek, transform the flood control walls on both sides of the river, reduce the top elevation of flood control walls, meet the safety requirements of water resources dispatching and flood control and drainage, and develop greening and leisure functions. Main environmental problems: At present, the land use on both sides of Suzhou Creek is extremely unreasonable, which not only causes water pollution, but also makes Suzhou Creek lose its due landscape value. Expected results: the green area is greatly increased, the water resources dispatching can be guaranteed, the pedestrian street is built on both sides of the strait, the leisure function is developed, and the land price on both sides of the strait is appreciated. Investment cost: 4.6 billion yuan. . Project description:
