Therefore, the urban sewage treatment system is the key to solve the shortage of water resources and serious environmental pollution.

However, my country is a large agricultural country with a vast rural area and a large population. Tens of millions of tons of domestic sewage are produced every day, and the pollution of rural sewage to the environment is becoming increasingly prominent. Therefore, attaching importance to and strengthening water pollution control in rural areas is one of the most important tasks to improve and improve the current rural environment, and it is also the only way to build a new countryside in our country. However, due to the wide area, dispersion, discontinuous water volume, unstable water quality and other characteristics of rural domestic sewage, coupled with the serious lack of rural water collection pipe network, it is difficult to centrally treat rural domestic sewage. At present, rural domestic sewage treatment facilities mainly adopt steel-concrete or brick-concrete structures. This structure has problems such as long construction period, large consumption of building materials, poor equipment matching, low degree of automation, difficult control of project quality and high labor intensity. People's lives have brought a lot of inconvenience, and have also destroyed the existing ecological environment, and there are deficiencies.
