[0003] The sewage recovery and treatment devices currently used in environmental engineering on the market often have unsatisfactory filtering effects when treating insoluble substances. These devices are prone to blockage problems during the filtration process, especially when treating sewage containing a large amount of suspended matter or particulate matter. The channels of the recovery devices are easily blocked, resulting in reduced treatment efficiency and may even require frequent shutdowns for cleaning.

[0004] In the patent document with publication number CN208594108U, an activated carbon sieve plate is installed inside the sewage treatment box to remove large particles of impurities. A throttle valve is installed above the drain pipe to adjust the water flow rate. A sewage pipe is installed at the bottom of the separation tank. The other end of the sewage pipe is connected to the flotation tank. The sewage can be treated by secondary circulation, with good purification effect and low operating cost. Rollers are installed at both ends of the support frame, that is, the position of the manual pull plate can be adjusted, which is convenient for loading and unloading and cleaning of sediment.

[0005] In view of the above patent, sewage is stirred for a long time inside the sewage tank, which causes dirt to form on the inner wall of the tank. Therefore, a device for cleaning the inner wall of the tank is proposed. Utility Model Content
