After adjusting the water quality and quantity of domestic sewage by homogenization tank, it continuously flows through anoxic tank, aerobic tank and secondary sedimentation tank for biochemical treatment. Denitrification and denitrification are carried out in the anoxic tank, and carbon removal and nitrification are carried out in the aerobic tank. Chemical agents were added before secondary sedimentation and phosphorus was removed by chemical method. The surplus sludge is sent to the sludge concentration tank for sludge digestion, stabilization, concentration and then dewatering disposal. The sludge is regularly shipped out to avoid secondary pollution.
