[0024] 1. After the wastewater enters the filtration tank through the inlet pipe, the filter plate filters the wastewater to reduce the impurities in the wastewater. The impurities on the surface of the filter plate move along the filter plate and fall into the collection tank. The impurities accumulate in the collection tank, which facilitates the collection of impurities and reduces the situation that the filter plate is blocked due to the accumulation of impurities on its surface, thereby improving the filtration efficiency.

[0025] 2. When there are impurities in the collection tank, the connecting block is detached from the filtration tank and moved away from the connection port, so that the connection port and the discharge port are opened, which facilitates the operator to clean the impurities in the collection tank.

[0026] 3. When cleaning the collection tank in the first chamber, the lifting assembly drives the partition plate to move downward in the vertical direction, so that the bottom of the partition plate contacts the connection part of the two filter plates, so that the first chamber is not connected to the second chamber, and the first pipe is closed, which facilitates the operator to clean the collection tank on one side. And cleaning the collection tank in the second chamber is the same as above.
