关于合流制排水系统提质增效方法与措施的思考
- Title:
- Thinking on Methods and Measures for the Quality and Efficiency Improvement of Combined Drainage System
- Keywords:
- combined drainage system; flood control; quality and efficiency improvement; overflow control; intelligent operation and maintenance
- 摘要:
- 结合我国部分城市合流制排水系统的实际情况，对合流制排水系统存在的管道易淤积、内涝风险高、溢流污染严重、高水位及低污染物浓度等特点进行分析，有针对性地提出了合流制排水系统开展提质增效工作的方法策略。合流制排水系统开展提质增效工作时，首先应提高排水系统的排水能力，满足区域排水防涝需求，在此基础上，提高污染物负荷收集率和污水处理厂进水污染物浓度，减少进入自然水体的污染物负荷，核心是应根据地区水环境容量、降雨及排水系统特征，制定符合地区情况的排水系统建设标准。根据方法策略，结合合流制排水系统的特点，提出“反向溯源、模型引导、病害治理、末端控制、智慧运维”等五大方面的实施方案，为合流制排水系统提质增效工作的开展提供参考。
- 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.
