1. Rural integrated sewage treatment equipment must meet current standard treatment and future recycling needs. According to different conditions such as topography and topography, road traffic conditions and construction layout of residential buildings in rural areas, rural sewage collection and treatment methods should be explored according to local conditions. This not only solves the current problem of rural sewage treatment and discharge standards, fully considers the needs of future sewage treatment and reuse, saves water resources, protects the water environment, and promotes rural economic development and coordination of resources and environment.

       2. The selection of rural integrated sewage treatment equipment should be based on one's own capabilities. Fully taking into account the overall weak financial situation of rural areas and the low actual affordability of farmers, the selection of technology should consider the use of treatment technologies with a high level of automated control, and select mature, reliable, economical and applicable sewage treatment technologies that are suitable for rural characteristics and rural realities.

       3. Rural integrated sewage treatment equipment needs to be simple to operate and simple to maintain and manage. In view of the weak economic foundation in rural areas and the low technical and management levels of employees, the selection of sewage treatment technology should pay attention to technology that is simple, stable in operation, easy to maintain and manage, utilizes local technology and management strength, and meets the needs of normal operations.
