The first-level system adopts physical and chemical pretreatment methods, including regulating tank, grid, neutralization tank, coagulation reaction tank, air flotation tank, electrolytic oxidation, internal electrolytic fluffy bed, inclined plate sedimentation, mainly to remove suspended solids and difficult-to-use materials in sewage. Part of the insoluble organic matter degraded by biological treatment methods is removed from the water body, further improving the water quality to meet the incoming water quality requirements of subsequent biological treatment units.
