雨水调蓄池对径流水质控制效果的模拟研究

Simulation Study on the Effect of Rainwater Storage Tank on Runoff Water Quality Control

随着城市化的发展,初雨水面源污染日益严重。针对当前调蓄池容积设计主要参照经验公式确定,方法上仍有不足。基于SWMM软件对调蓄池入流过程线和污染物浓度变化过程进行模拟,最终确定调蓄池容积。将此方法应用于深圳市某城区降雨径流面源污染控制措施中,研究结果表明,依此方法能明确调蓄池污染物消减效果,增强调蓄池容积设计的合理性,为控污工程提供研究思路。

With the development of urbanization,the pollution of primary rainwater sources has become increasingly serious.The design of current storage tank volume is mainly determinded by empirical formula,and there are still some shortcomings of the method.Based on SWMM software,the inflow process line of the storage tank and the concentration change process of the pollutants are simulated to finally determine the volume of storage tank.This method is applied to the control measures of non-point source pollution of rainfall runoff in a certain urban area of Shenzhen,and the results show that this method can clarify the pollutant reduction effect of the storage tank and enhance the rationality of the design of the storage tank volume,which has certain reference value in future pollution control projects.
