As shown in fig. 3, the working principle of the present invention is: when sewage flows in, the sewage enters the water collecting tank through the filter G1 and the main pump B1. Along with the entering of sewage, the rising of sewage water level in the water collection tank, when reaching the start water level of the set pump B1, the liquid level meter gives a signal, the main pump B1 is started to drain water through the control cabinet, the sewage with pressure reversely passes through the filter G1 at the moment, the filter is backwashed, the check valve ZF1 is closed under the pressure of water, and the check valve ZF3 is opened to drain the sewage to a sewage discharge pipeline. At this time, if water still enters, the water can enter the water collecting tank through the opened check valve ZF2, the filter G2 and the main pump B2, and the sewage lifting of the main pump B1 is not influenced. When the sewage in the water collecting tank is reduced and the water level is reduced to a set low water level (water shortage protection), the liquid level meter transmits a signal to the control cabinet, and the main pump B1 is stopped by the control cabinet. When the two main pumps B1 and B2 are both in operation, water still enters, and water can enter through the anti-blocking water inlet device, so that the main pumps B1 and B2 are not influenced to lift sewage. When the water inflow is large and the water level reaches the ultrahigh water level, the liquid level meter transmits signals to the control cabinet, and the double main pumps B1 and B2 can operate simultaneously through the control cabinet; when the control cabinet normally operates, the control cabinet automatically realizes the running of the double main pumps B1 and B2 in turns, and the double main pumps are mutually standby.

When one of the sewage pumps breaks down, the fault indicating lamp is turned on, and the control system enables the other sewage pump to start and operate, so that the fault mutual switching function is realized.

2) the sewage level in the water collecting tank 8 rises, when the set starting water level of one of the main pumps 11 is reached, the liquid level meter gives a signal, and one of the main pumps 11 is started to drain water through the control cabinet;

3) under the action of the step 2), sewage with pressure reversely passes through the sewage discharge lifting line to perform a back flushing effect on the lifting channel and the filter, under the pressure of water, the water inlet check valve ZF1 is closed, the water outlet check valve ZF3 is opened to discharge the sewage to the water outlet 1, and the sewage enters a sewage discharge pipeline;

4) under the action of the step 3), if water still enters, the water enters the water collecting tank through a filter G2 and another main pump B2 by opening a water inlet check valve ZF2 on the other set of pollution discharge lifting line;

5) when the sewage in the water collecting tank 8 is reduced and the water level is reduced to a set low water level (water shortage protection), the liquid level meter transmits a signal to the control cabinet, and the control cabinet controls to stop the operation of the main pump 11;

6) the upper level meter detects that the water inflow is large, when the water level reaches the ultrahigh water level, the level meter transmits a signal to the control cabinet, and the control cabinet controls the double pumps to operate simultaneously;

7) and 6), under the action of the step 6), when the double pumps are operated, water still enters, and the water enters the water collecting tank 8 through the anti-blocking water inlet device 12.
