Background

It is a common situation in the process design to build a toilet in the basement of a building. At this time, no matter how many sanitary wares are arranged in the toilet, there are two common methods:

one method is that a water collecting pit is arranged under the ground of a basement, and sewage of sanitary ware is collected together and then is lifted by a submersible sewage pump to be discharged to an outdoor underground sewage pump well;

the other method is that the sewage in the toilet is automatically drained into an outdoor underground sewage pump well, and a sewage inspection well which is drained to the vicinity of the pump well is lifted by a submersible sewage pump.

The first method has three disadvantages: firstly, solid matters such as excrement and the like exist in sewage, and the sewage is not cleaned for a long time and is easy to cause blockage; secondly, because the sump pit is shallow, the submersible sewage pump which is started and stopped according to the water level is not reliable in operation; thirdly, the sealing performance of the water collecting pit is poor, the water collecting pit has smell, and the sanitation condition is poor.

The second method is to build a pump well outdoors, which has the disadvantages of deep depth, large investment and inconvenient management. In addition, the toilet in the building is arranged to be vertically staggered, so that the toilet is far away from the vertical drainage pipe, but the vertical drainage pipe cannot be suspended below the floor slab. The thickness of the cushion layer is thicker and can reach 350-400 mm sometimes, which brings difficulty to the use of the toilet and the floor layout of the building.
