If the filter unit cell 122 closer to the dirt suction port 14 is blocked, the dirt and the garbage can enter other filter unit cells 122 through the garbage passage above the partition plate 20. The remaining filter cells 122 not filled with garbage can still take on the filtering function, and the filtering of the sewage is not affected. The sewage and garbage entering the filtering chamber 12 flow out of the filtering chamber 12 through at least one filtering unit cell 122, the garbage is remained in the filtering unit cell 122 after the sewage is filtered by the filtering chamber 12 and the filtering unit cell 122, and the filtered sewage flows out of the filtering chamber 12 and enters a sewage tank and other structures.

Wherein, two adjacent baffles 20 and the casing 10 enclose a filter unit cell 122, or the baffles 20 and the casing 10 enclose a filter unit cell 122.
