1.3 Working Principle

1. The sewage enters the grid pool first, and the domestic garbage in the domestic sewage is initially removed by the grille
2. Then enters the regulating tank to adjust the water quality and quantity
3. And then is pumped to the anoxic tank by the lifting pump, and the submersible mixer is arranged in the anoxic tank to perform nitrification and denitrification. Combined with aerobic denitrification and dephosphorization, the macromolecular organic particles are decomposed into small molecular organic particles, which can improve the biodegradability of the wastewater.
4. Then the sewage flows into the aerobic pool and conducts aerobic biochemical reactions. The substance is degraded by biooxidation, and the effluent flows to the secondary sedimentation tank for solid-liquid separation. The supernatant of the sedimentation tank flows into the clear water pool, and then passes through the ultraviolet disinfection equipment to kill the harmful bacteria in the water and discharge to the standard.
5. The sludge in the secondary settling tank is returned to the aerobic tank by the sludge return pump, and the other part of the sludge is sedimented by itself to the sludge tank. The sludge in the sludge tank is periodically dewatered by the sludge dewatering machine. The sewage sludge supernatant is returned to the conditioning tank by the mixed liquid reflux pump for further treatment.
