基于SWMM的初期雨水调蓄池容积确定及截污效能模拟
|
摘要
雨水调蓄池通常借助经验公式确定容积,可信度略显不足。对此,选用模型法即通过模拟典型降雨下调蓄池的工作过程,结合排放目标确定调蓄池容积。将此方法应用于以南昌市儒乐湖流域为研究区域的非点源污染物控制过程中,模拟结果表明,该方法确定的调蓄池容积可有效受纳初雨冲刷带来的污染物,达到削减非点源污染物的目的。研究成果可在实际工程中推广应用。
During the traditional design process,empirical formulas are commonly used when calculating the volume of storm water storage tanks.But there is a certain degree of lack of credibility.In this study,model method is used to simulate the working process of a storage tank under a typical rainfall.And then the volume of storage tank is determined by combining with the discharge target.Finally,this method is applied in controlling non-point source pollutants of Rule Lake in Nanchang City.The result shows that a tank designed by this way can collect the swashed by initial rainwater effectively,and achieve the goal of reducing the influence of pollution.The research results can be popularized and applied in actual project.
