The flushing ring 52 is sleeved on the outside of the filter cartridge membrane 3. A flushing hole 521 facing the filter cartridge membrane 3 is provided on the outer ring wall of the flushing ring 52. The direction of the flushing hole 521 is set away from the axis of the flushing ring 52. The middle part of the outer ring wall of the flushing ring 52 is rotatably connected to the inner ring wall of the baffle disc ring 51. The outer ring wall of the baffle disc ring 51 is axially slidably connected to the wall of the treatment cartridge 2. The structural design of the baffle disc ring 51 and the flushing ring 52 can play a cross-sectional role on the cross section of the sewage flow cavity 21. Specifically, for example, sewage is introduced into the sewage cavity 21 from the left pipe 6. When the filtered water in the filter cartridge membrane 3 is discharged from the right tube 29 during the flow chamber 21, the sewage in the sewage flow chamber 21 will drive the baffle ring 51 to move to the right end of the treatment cartridge 2. At the same time, the sewage passing through the flushing hole 521 will drive the flushing ring 52 to rotate, thereby achieving the effect of continuously flushing the filter cartridge membrane 3 and avoiding the accumulation of dirt on the wall of the filter cartridge membrane 3 when treating sewage for a long time.
