合流制排水系统溢流调蓄技术研究及应用实例分析

Study of Overflow Storage technology of Combined Sewerage System and Analysis of Practical Example

排水系统雨天溢流对受纳水体的污染已日益受到关注。合流制排水系统溢流调蓄技术是控制面源污染、削减污染负荷的一项关键技术。建设调蓄池以减少排江污染负荷是重要的工程措施之一。该文介绍了调蓄池的原理和作用,并结合上海的实际情况,分析阐述了调蓄池的计算方法,为合流制排水系统面源污染控制提供技术支持,并可总结推广应用于上海及其他城市合流制排水系统污染物控制工程。

The aquatic pollution caused by the combined sewerage overflow in raining day on the water accepting body has increasingly come to our attention. The storage technology of combined sewerage overflow is a key technology to control the surface pollution and cut pollution load. The construction of the retention basin is one of the important engineering measures to decrease the pollution discharge into the rivers. The article introduces the principle and the action of the retention basin. And with the instance of Shanghai, the article analyzes and sets forth the calculation methods for retention basins, which provides the technical support to control surface pollution of the combined sewerage, and sums up and popularizes the application to the pollutant control of the combined sewerage in Shanghai and the other cities.
