A reciprocating screw is fixed to the shaft end of the motor near the bottom of the partition. When filtering sewage, the sewage enters the box body through the water inlet pipe, is filtered by the filter element, and is discharged from the outlet pipe. At the same time, the reciprocating screw is driven to rotate by the motor, and the reciprocating screw drives the lifting frame to move through a threaded connection. The lifting frame drives the brush frame to move up and down, and the brush frame cleans the surface of the filter element with bristles, can automatically clean the surface of the filter element during the sewage treatment process, avoid clogging of the filter holes of the filter element, and can effectively improve the filtration of the sewage treatment device.
