A first vibration motor 905 is arranged on the filter screen 902. The submersible sewage pump 10 pumps the sewage containing impurities into the water tank 901. The filter screen 902 filters the impurities. The first vibration motor 905 vibrates to shake off the impurities adhering to the filter screen 902 and precipitate them at the bottom of the water tank 901. A water filling port 903 is arranged on the top of the water tank 901. A valve 904 is arranged at the bottom of the outer side of the water tank 901. Open the valve 904 and add clear water into the water tank 901 from the water filling port 903 to conduct backwashing on the filter screen 902. The impurities at the bottom of the water tank 901 are discharged from the valve 904.

[0034] To obtain better sewage filtration effect, a filter layer such as activated carbon can be arranged above the filter screen 902, which is the prior art and will not be elaborated here.
