[0002] Sewage is a kind of wastewater generated in people's daily lives. It contains a large amount of solid waste and garbage. It needs to be treated and can only be discharged after meeting the discharge standards. In basements, ships, vehicles and other places far away from drainage risers and with poor drainage conditions, the domestic water in the bathroom is generally collected and treated and discharged into fixed sewage lifting tanks. Then, sewage lifts are used to discharge the water into urban sewage pipes that are higher than the underground sewage pipes.

[0029] A crushing knife 1 7 is fixedly connected to the outer surface of the crushing shaft 6, and a crushing knife 2 8 is fixedly connected to the outer surface of the crushing shaft 6. The crushing knife 1 7 and the crushing knife 2 8 are different in length and shape, which can effectively improve the crushing efficiency of solid waste. In addition, with the cooperation of the filter cartridge 2 and the crushing knife 1 7 and the crushing knife 2 8, the knife group and the sewage rotate in the opposite direction, so that the solid waste can be crushed more quickly. When the solid waste is not crushed to the point where it can be discharged from the filter cartridge 2, it will continue to rotate with the filter cartridge 2 and then be crushed by the crushing knife group until it is crushed to the point where it can be discharged from the filter cartridge 2 along with the sewage, effectively preventing the pipeline from being blocked.

[0030] One end of the crushing shaft 6 is inserted into the inner wall of the filter cartridge 2, and a sewage lifting pump 9 is arranged inside the sewage lifting box 1. The sewage lifting pump 9 is equipped with a sewage lifting pipe 10, and one end of the sewage lifting pipe 10 is connected to a preset sewage pipe. One end of the sewage lifting pipe 10 is fixedly penetrated through the inner top wall of the sewage lifting box 1.
