In the above embodiment, in operation, waste water enters from the inlet 101 at the top end of the first housing 1 and flows down into the baffle 2. After being filtered by the baffle 2, impurities are remained on the baffle 2, part of wastewater flows downwards from meshes of the baffle 2, and part of wastewater flows downwards along the baffle 2. Under the impact of the wastewater flow, the impurities trapped by the baffle 2 also flow along the baffle 2, eventually falling into the impurity collector 3.

The part of the baffle 2 positioned at the top, which is opposite to the water inlet 101, is solid. The baffle 2 is obliquely arranged, the top end of the baffle 2 is fixedly connected with the inner wall of the first shell 1, and a gap is reserved between the bottom end of the baffle 2 and the inner wall of the first shell 1. The purpose of this is to cause the wastewater to flow downwards along the path of the baffle 2, acting to impact the impurities located on the baffle, causing them to flow, avoiding blockages. Meanwhile, the intercepted impurities of the baffle plate at the top are larger, and the intercepted impurities of the baffle plate at the bottom are smaller.
