雨水调蓄池优化及污染物削减情况分析

Analysis on Optimization and Pollutant Reduction of Rainwater Storage Pond

为解决城市排水系统造成水质污染问题,以某河调蓄池为研究对象,对其雨水管网规划进行分析和概化,讨论雨水排放的效率和安全性的影响因素,研究结果表明:随着蓄水池调蓄量的增加,污染物削减率也相应提高。为达到最佳的水质改善效果,应尽可能增加调蓄池的有效容积可排水体积。调蓄量越大,污染物去除率越高。调蓄池的有效容积对于提高雨水径流水质有重要作用,雨水调蓄池是一种简单而有效的初期雨水污染控制措施。

In order to solve the problem of water pollution caused by urban drainage system,this paper takes a river storage tank as the research object,analyzes and generalizes its rainwater pipe network planning,discusses the factors affecting the efficiency and safety of rainwater discharge.The research results show that:With the increase of reservoir storage capacity,pollutant reduction rate also increases.In order to achieve the best water quality improvement effect,the drainage volume of the effective volume of the storage tank should be increased as much as possible.The larger the storage capacity,the higher the pollutant removal rate.The effective volume of stormwater regulating pond plays an important role in improving the water quality of stormwater runoff.Stormwater regulating pond is a simple and effective measure to control initial stormwater pollution.
