Background

As is well known, a municipal drainage system is a system which is specially used for discharging and cleaning rainwater, domestic sewage and industrial sewage, and is widely used in municipal works. Existing municipal drainage systems generally include combined and split systems. The combined flow refers to that sewage and rainwater are combined and sent to a sewage treatment plant for treatment. However, under the conditions of heavy rain or abundant water, the discharged water amount is greatly increased due to the confluence of rainwater and sewage, and the treatment capacity of a sewage treatment plant is limited, so that part of rainwater and sewage can flow backwards, and the whole drainage system is influenced. The split flow system is to separately discharge the rainwater pipeline and the sewage, and the rainwater is directly discharged to a natural water body, but because the discharge amount of the rainwater is different from that of the sewage, the problem of unbalanced drainage pressure exists.

In addition, in the existing domestic sewage and industrial sewage discharge process, harmful gas is often generated and returns to the road surface through a discharge pipeline, so that secondary pollution to the environment is caused, and meanwhile, the harmful gas often influences the health of human bodies.
