The wastewater first flows through an artificial grid to remove floating debris from the wastewater, and then flows into a regulating tank to balance the water quality and quantity of the original wastewater; To prevent SS from settling in the regulating tank, several aeration hoses are installed in the regulating tank for agitation. At the same time, the regulating tank has hydrolysis and acidification functions, which can degrade some large molecule organic pollutants into small molecule pollutants and remove some organic pollutants.

Install a submersible sewage pump in the regulating tank to lift the sewage to the contact oxidation tank. In the contact oxidation tank, organic pollutants are deeply degraded by aerobic microorganisms on the biofilm, and the road discharge standards may be better than or meet the discharge standards; The effluent from the contact tank flows into the secondary sedimentation, and after sedimentation, the effluent meets the discharge standards.

The remaining sludge and grid residue enter the sludge well and are then lifted to the sludge drying plant by a sludge pump. After natural drying and dewatering, they are transported for disposal.

The filtrate produced by drying and dehydration flows back to the regulating tank and is then processed by the treatment system.
