摘要
随着我国城市化进程的加快,城市不透水区域面积急剧增加,导致雨水径流外排总量和峰值流量增加,同时城市区域人类活动带来的道路交通、地表沉积物、空气沉降等污染,最终在雨水径流的冲刷作用下排入受纳水体,对城市排水防涝和水体水质带来了极大的威胁。针对上述问题,雨水调蓄池在城市雨水管理中得到越来越广泛的应用,但目前普遍存在投资大、设计功能单一、利用效率较低等问题。分析了雨水调蓄池内水质变化规律,同时模拟某下凹桥区调蓄池在不同重现期及进水浓度下污染物的变化规律,以期为雨水调蓄池优化运行和实时控制提供参考。
With the acceleration of urbanization in China, the urban impervious area has increased dramatically, leading to the increases of rainwater runoff discharge volume and peak flow rate. Meanwhile, road traffic pollutants, surface sediments, air bell laid and other pollutants resulted by human activities in the urban areas are discharged into receiving waters with rainfall runoff, which has brought great threat to the urban drainage and waterlogging prevention system and water quality. In response to the above problems, rainwater storage tank has been widely used in urban rainwater management, but there are many problems such as large investment, single design function and low utilization efficiency in it. In this article, the variation law of water quality of the rain water storage tank was analyzed and the variation law of water pollutants in storage tank for sunken bridge under different return periods and influent concentrations were stimulated to provide a basis for optimized operation and real-time control of the storage tank.
