[0012] The beneficial effects of this utility model are:

[0013] 1. First, wastewater and solid debris flow through the first tank into the interior of the seepage block, and then into the interior of the fourth tank. The wastewater is then filtered through a filter screen into the square holes. A triangular block is installed at the lower end of the seventh tank to prevent wastewater from flowing into the collection tank. Then, the second electric cylinder is opened, which pushes the extension block upward. When the upper end of the extension block reaches the top of the fourth tank, the second electric cylinder is closed, and then the first electric cylinder is opened. The first electric cylinder pushes the push block and the extension block to move, and the push block and the extension block push the solid debris into the interior of the seventh tank. Since the upper end of the triangular block is inclined, the solid debris can smoothly cross the triangular block and reach the interior of the collection tank, thus achieving separate treatment of liquid and solid.

Then the above operation is repeated to push the solid debris into the collection box, making it easier to clean the filter screen. Attached Figure Description
