A septic tank (huàfènchí) is a device that treats feces and filters and settles it. The principle is that the solidified objects decompose at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from being blocked and giving the solidified objects (feces and other garbage) sufficient time to hydrolyze. A septic tank refers to a small treatment structure that separates domestic sewage into compartments and performs anaerobic digestion of sludge.

Process flow

The septic tank is a treatment equipment that uses the principles of sedimentation and anaerobic fermentation to remove suspended organic matter in domestic sewage. There is a partition inside the high-efficiency corrugated fiberglass septic tank. The holes on the partition are misaligned up and down to prevent short flow, and the entire tank is divided into three parts: a primary anaerobic chamber, a secondary anaerobic chamber and a clarification chamber. The bottoms of the primary and secondary anaerobic chambers are connected, and "MDS special packing" is added inside.

This kind of separation reduces the contact time between sewage and sludge, so that the acid fermentation and alkaline fermentation processes do not interfere with each other. At the same time, the presence of filler increases the contact surface area between sewage sludge and anaerobic bacteria. , greatly improving the reaction efficiency.
