The water paint sewage discharged from the production workshop, after intercepting large suspended particles through the grid, enters the sewage regulating pool where the water quality and quantity are regulated. The sewage pump is used to lift the homogeneous sewage to the reaction tank for coagulation reaction, and then it is discharged into the first sedimentation tank for solid-liquid separation. The supernatant is discharged into the anaerobic filter tank for anaerobic biodegradation. After mixing with domestic sewage in the mixing tank, it is transported to the contact oxidation tank for aerobic biological treatment, and finally discharged into the second sedimentation tank for solid-liquid separation, The supernatant is filtered and discharged up to standard. 1、 The sludge generated in the second sedimentation tank and anaerobic filter is discharged into the sludge thickener, and then dehydrated by the plate and frame filter press before being outsourced for treatment. The filtrate after pressure filtration returns to the sewage regulating tank for re treatment.
