摘要
生物滞留设施作为低影响开发技术的典型技术之一,不仅具有调控雨水径流量和径流峰值的作用,还能在一定程度上控制城市面源污染。文章对生物滞留设施的构成和功能进行了介绍。结合国内外实际应用案例和模拟试验研究,对生物滞留设施去除城市雨水径流中主要污染物的机理和处理效果进行了总结分析,指出目前具体应用中存在的问题,以期为我国海绵城市建设和该项技术的推广应用提供参考。
As one of the typical technologies of low impact development,bioretention facility can not only regulate rainwater runoff and peak runoff,but also control urban non-point source pollution.The composition and function of bioretention facility are introduced.Combined with the practical application cases and simulation test studies at home and abroad,the mechanism and treatment effects of the removal of main pollutants in urban rainwater runoff by bioretention facility are summarized and analyzed-And problems in the specific application are pointed out,so as to provide reference for the construction of sponge city in China and the promotion and application of this technology.
