The working process of the invention is as follows:

first, the drum motor 25 drives the filter screen 22 to rotate through the central shaft 24, and the propelling motor 33 drives the screw rod 32 to rotate, so that the brush barrel 5 is driven by the screw nut 34 to horizontally move left and right. Then, the sewage containing sand is directly injected into the screen 22 through the pipe 29 along the pipe 27. Larger stones are trapped in the sieve 22, while water and smaller sand fall through the sieve holes into the bottom of the outer tub 1. Meanwhile, the clean water pump 82 injects the clean water in the kettle body 61 into the cylinder 51 along the water inlet, and then the clean water is sprayed out from the plurality of nozzles 511 to impact on the surface of the filter screen 22, so that the sand stuck in the filter holes is washed loose.
