Water pumps 11 are fixedly connected to the front ends of the first flange pipes 10. The bottom ends of the water pumps 11 and the mounting base 1 are fixedly connected. At the positions of the left and right parts of the mounting base 1, which are slightly forward, there are second water troughs 12. The bottom ends of the water pumps 11 are both communicated with the second water troughs 12. Second flange pipes 13 are fixedly connected to the rear ends of the filter troughs 8 of the mounting base 1. Upright check valves 14 are fixedly connected to the tops of the second flange pipes 13. A confluence pipe 15 is fixedly connected to the top of the upright check valve 14. A waste discharge pipe 16 is fixedly connected to the middle position of the top of the confluence pipe 15.

[0022] The mounting base 1 is a rectangular base. Water inlet valves are provided at the top and the front side of the water distribution tank 2. Water outlet ports are provided on both the left and right sides of the water distribution tank 2. The water distribution tank 2 can divert sewage and input it into two sets of treatment mechanisms; the diversion pipes 5 are both bent pipes. The diversion pipes 5 and the inverted check valves 6 are both inclined. The first water troughs 7 are both inclined. The filter troughs 8 are both horizontally arranged. The second water troughs 12 are both vertically arranged. The second water troughs 12 can connect the bottom interfaces of the water pumps 11 with a water storage tank; the filter screens 9 are both cylindrical shell structures with openings at the left ends. The filter screens 9 and the first flange pipes 10 are both horizontally distributed. The diameters of the filter screens 9 are both smaller than the maximum diameter of the first flange pipes 10. When necessary, the first flange pipes 10 can be removed and the filter screens 9 can be taken out for maintenance or replacement; the second flange pipes 13 are both bent pipes.

[0023] Workflow: Before using the device, install it at the designated position. Fix the mounting base 1 on the top of the water storage tank, connect the two inlet valves of the water distribution tank 2 to the suction pipes respectively. Insert both suction pipes into the sewer and make the bottom ends of the suction pipes lower than the liquid level in the sewer. Connect the bottoms of the two second water troughs 12 to the two water delivery pipes of the water storage tank, and the bottom ends of the water delivery pipes are close to the bottom surface of the water storage tank. Connect the waste discharge pipe 16 to the input port of the impurity collection box. Then turn on the power. The water pump 11 of this device is an electrical instrument. This device is equipped with an external controller, and the operating state of the water pump 11 can be controlled through the external controller. The inverted check valve 6 and the normal check valve 14 of this device are both one-way valves. Among them, the inverted check valve 6 can only transport substances downward, and the normal check valve 14 can only transport substances upward. The above are all prior arts. When the device is in normal use, manually operate the external controller to make the water pump 11 run. The water pump 11 pumps water through the connection port at its rear side and discharges water through the connection port at its bottom. At this time, the inverted check valve 6 is pressed to open, and the normal check valve 14 automatically closes. The water distribution tank 2 can suck up the sewage in the sewer through the suction pipes, and exhaust through the exhaust connection pipe 3 and the exhaust valve 4. The sewage is shunted through the shunt pipe 5. The two inverted check valves 6 transport the sewage through the first water trough 7 and the filter water trough 8 to the first flange pipe 10. When the sewage passes through the filter water trough 8, it is filtered through the filter net 9, and the impurities are intercepted behind the filter net 9. The filtered sewage enters the water storage tank through the water pump 11 and the second water trough 12. The water storage tank drains regularly. When the device needs to clean impurities, only need to manually operate the external controller to make the water pump 11 run in reverse. The water pump 11 pumps water through the connection port at its bottom and discharges water through the connection port at its rear side. At this time, the inverted check valve 6 automatically closes, and the normal check valve 14 is pressed to open. The second water trough 12 can suck up the water in the water storage tank through the two water delivery pipes of the water storage tank. This part of the water reaches the filter net 9 through the first flange pipe 10, can carry impurities and pass through the filter water trough 8 to reach the second flange pipe 13, and then pass through the normal check valve 14 and converge in the confluence pipe 15, and is discharged into the impurity collection box through the waste discharge pipe 16, so as to be quickly cleaned. The device can filter the sewage during the process of sucking and lifting the sewage, and automatically discharge the impurities stored inside the device through the reverse suction function of the second water trough 12, and there is no need to disassemble and assemble the device during the cleaning process, which is time-saving and labor-saving.
