Inlet water garbage filtering device and filtering method for sewage treatment plant

The invention discloses an inflow garbage filtering device for a sewage treatment plant and a filtering method, and relates to the field of sewage treatment.The inflow garbage filtering device comprises a water tank, the inner walls of the two sides of the water tank are rotationally connected with conveying nets, and the upper wall of one end of the water tank is fixedly connected with a garbage bin. When sewage in the water tank passes through the conveying net, the sewage passes through mesh holes, garbage cannot pass through the mesh holes, the filtered garbage is conveyed to the garbage bin along the conveying net, most garbage can be filtered and screened out due to different sizes of the garbage and small mesh holes of the conveying net, the subsequent dehydration treatment is more convenient, and the labor intensity of workers is reduced. When the conveying net rotates, the rubber bristles on the surface of the cleaning cylinder make contact with the inner wall of the conveying net, due to the fact th
