[0052] It should be pointed out that during the use of the device, the bottom of the grid plate 807 is generally in contact with large particles of impurities. After the next sewage injection and sedimentation, the grid plate 807 enters the sedimentation tank 3 and moves up and down to clean the particles attached to the bottom surface, so there is no need to replace it frequently. The filter plate 10 is used to filter small particles or sludge, so it is easy to get blocked and needs to be removed and cleaned frequently. Therefore, the filter plate is installed in the filter tank 4 through the installation mechanism 9, which has the advantage of convenient disassembly and cleaning.
