A large amount of untreated domestic sewage is directly discharged into the river, causing water pollution. The sewage cannot be discharged in time, causing the water to stink, and the living environment is getting worse, which has affected the lives of residents.

There are many sources of domestic sewage in rural areas, mainly the sewage produced by rural residents in their daily lives and the excrement of poultry and livestock raised in rural areas. In addition to the large particle residues carried by the sewage, it is also easy to be mixed with various domestic garbage, branches and leaves, etc. Moreover, according to the construction plan tailored to local conditions, the rural areas are scattered and the foundations are uneven. It is impossible to build a reasonable rainwater and sewage diversion drainage system like the city. The main drainage system is the rainwater and sewage combined system. Even if domestic sewage is collected by building a drainage pipe network, the drainage pipe network will be blocked due to the accumulation of garbage residues. Coupled with the lack of awareness of environmental protection, it will be difficult to clear and operate the drainage network in the later stage. Therefore, it is necessary to design an anti-clogging and cleared combined open channel terminal slag interception method.
