Put the flocculant and clean water into the reagent reaction tank 8 through the drug inlet 7 respectively, start the stirring motor 6, so that the stirring motor 6 drives the stirring rod 5 to stir. After the reagent in the reagent reaction tank 8 reacts fully, open the valve 4 to inject the reagent in the reagent reaction tank 8 into the sedimentation tank 3. The flocculation effect of the flocculant will cause the impurities in the sewage to flocculate together and settle at the bottom of the sedimentation tank 3. After the flocculation work is completed, the sewage in the sedimentation tank 3 will be divided into three layers, from top to bottom. Clean water, muddy water mixture and silt. At this time, the water baffle 11 can be lifted upward along the fixed groove 16 by pulling the handle 17, so that the clean water in the sedimentation box 3 will flow into the water storage tank 1 from the water outlet 15, and the mesh structure of the water outlet 15 will prevent impurities in the muddy water mixture from falling into the water tank 1.
