The pollution problem is the first driving force of the environmental industry. The ultimate goal of water environment management must be the improvement of water environment and water quality, so that ordinary people can really see the shallow bottom of the green fish. Recently, the State Council Western Region Development Leading Group meeting pointed out that China is still in the process of urbanization, and the urbanization rate is only about 58%. The construction of urban sewage facilities is the foundation of urbanization construction, which contains huge investment potential. Especially for the urbanization of the western region, the construction of urban sewage and garbage treatment facilities is a short board in the short board. This is not only a major project of people's livelihood, but also a major ecological engineering and development project.
