1, high treatment degree, low sludge output, try to use energy-saving treatment technology.
2. The sewage treatment plant should be located in the downwind of residential areas as far as possible, and keep a certain distance from other buildings to reduce the impact on the environment.
3. The wastewater treatment process should be as simple and practical as possible and easy to manage.
4, in the facade layout should try to use three-dimensional layout, make full use of underground space. The layout should be compact to save land.
5. The design and construction of sewage treatment equipment in residential areas must be combined with the overall planning and architectural characteristics of residential areas, that is, the appearance design should be coordinated with the architectural environment of residential areas in order to be beautiful.
6. The equipment is standardized and modularized, with convenient construction and installation, simple operation and stable equipment performance.
The population of this community is increasing gradually. Therefore, sewage treatment plants in residential areas should take predictable development planning as the basis for process design. According to the situation in China, a design cycle of 20 years can be considered.
8. The treatment structure has wide adaptability to hydraulic load and organic load, which makes the system have good impact load resistance.
9. Requirements and treatment degree of treated sewage. Generally speaking, different communities have different requirements for treated sewage. The treatment degree should be determined according to the relevant regulations and the requirements of the local environmental protection department to ensure the effluent quality. If the effluent is treated by land treatment method, it should be calculated according to the requirements of land treatment method.
