When the utility model treats chemical wastewater, the chemical wastewater and the flocculant enter the tank body 1 through the liquid inlet pipe 17 and the dosing pipe 18 respectively, and the chemical wastewater is precipitated and flocculated by the flocculant. Then, the treated chemical wastewater passes through the filter plate 12 and is discharged from the liquid discharge port. The flocculants produced by the flocculant are filtered and retained in the tank body 1 through the filter plate 12. When it is necessary to clean the inside of the tank body 1, the motor 21 can be started through the external control panel, and the motor 21 drives the second rotating shaft 9 to rotate, so that the tank body 1 is cleaned. 1, the flocculation and other solid wastes on the inner wall of the fertilizer 1 are scraped off to the filter plate 12 and the upper part of the fixed block 3. When the second rotating shaft 9 rotates, the waste discharge plate 11 and the second bevel gear 10 are driven to rotate at the same time. The flocculation and solid wastes scraped off by the scraper 13 and accumulated on the filter plate 12 and the upper part of the fixed block 3 are scraped to the upper part of the waste discharge trough 5 by the waste discharge plate 11, and fall into the waste discharge trough 5. The second bevel gear 10 drives the first rotating shaft 6 to rotate through the first bevel gear 8 meshing therewith, so that the flocculation and solid wastes in the waste discharge port 15 are transported to the upper part of the waste discharge port 15 on the fertilizer discharge pipe for discharge through the auger blades 7 on the surface of the first rotating shaft 6.
