- Abstract:
- Combined with the actual situation of combined drainage system in some cities in China, the characteristics of combined drainage system, such as easy deposition of pipeline, high risk of waterlogging, serious overflow pollution, high water level and low pollutant concentration of influent, are analyzed. We put forward the methods and strategies to improve the quality and efficiency of the combined drainage system. We first improve the drainage capacity of the drainage system to meet the requirements of the regional drainage and waterlogging prevention. On this basis, the collection rate of pollutant load and the influent pollutant concentration of sewage are increased, and the pollutant loading into natural water body is reduced. The core is to formulate drainage system construction standards according to the regional water environment capacity, rainfall and drainage system characteristics. With the characteristics of combined drainage system, the implementation scheme of “reverse traceability, model guidance, disease treatment, terminal control, intelligent operation and maintenance” is proposed. It provides a reference for improving the quality and efficiency of the combined drainage system.
