| 摘 要： | 不同低影响开发(LID)技术组合对于控制城市面源污染具有重要应用价值,但是其对城市面源污染形成过程(污染物累积-冲刷-输送)的影响及污染负荷削减效果的评估鲜见报道.本研究以深圳市国际低碳城为例,分析了6场降雨事件下透水路面-生物滞留池组合对城市面源晴天污染物累积量、降雨径流冲刷量、不同LID设施的削减量、溢流的负荷量的影响.结果表明,研究区地表颗粒物平均累积量为(15.80±3.79)g·m~(-2),粒径250μm的颗粒物质量占比约为65.14%;6场不同强度降雨对地表颗粒物的平均冲刷率为17.15%,粒径105μm的颗粒物冲刷率为62.71%~74.94%;降雨冲刷地表径流污染物SS、TN、TP的平均污染负荷分别为2.02、0.025、0.001 3 g·m~(-2);透水路面下渗、过滤作用对污染物SS、TN、TP的去除率分别为70.26%、46.29%、19.27%;生物滞留池对径流二次净化去除率分别为85.25%、20.22%、70.27%;入河径流污染物SS、TN、TP的平均污染负荷分别为0.08、0.011、0.000 3 g·m~(-2),是地表冲刷污染负荷的4.05%、43.47%、24.39%.透水路面-生物滞留池组合应用对道路径流中污染物的净化效果显著.通过定量化表征透水路面-生物滞留池组合应用道路的城市面源污染形成过程,以期为城市面源污染形成过程的污染负荷估算及LID工程绩效评估提供科学依据,为LID在国内的推广应用和海绵城市设计提供参考.
