[0004] During the use of the device, impurities on the surface of the filter are promptly removed by the brush bar. However, since there are a lot of flocs in the wastewater, these flocs will be entangled on the surface of the brush bar. If they are not cleaned up in time, the brush bar will affect the cleaning of the filter surface, causing the surface of the filter to be blocked, thereby reducing the filtration efficiency.
