摘要
如何有效控制城市雨水径流所带来的面源污染已成为城市管理工作所面临的重要难题之一。作为城市暴雨最佳管理措施(BMPs)中的技术之一,生物滞留池可有效控制城市面源污染。总结了生物滞留池在改善城市雨水径流水质方面的研究进展,简要分析了生物滞留池去除污染物的机制。研究结果表明,生物滞留池对雨水径流中的总悬浮颗粒物(TSS)、重金属、油脂类及致病菌等污染物有较好的去除效果,而对N、P等营养物质的去除效果不稳定。最后,对生物滞留池改善城市雨水径流水质进一步的研究方向进行了展望。
Proper and effective control of the non-point source pollution causing by stormwater runoff has become a major challenge for many urban managers.Bioretention as one of the best management practices（BMPs） of urban stormwater could be employed for effective control the non-point source pollution.This paper summarizes the research progress of bioretention for improving urban stormwater runoff quality,and presents the associated pollutant removal mechanisms simultanly.The literature data of select field and lab studies have demonstrated that bioretention is effective for removing TSS,heavy metals,oil grease and pathogenic bacteria from stormwater runoff,while its nutrient removal effectiveness is not stable depending on the variable local factors such as the soil composition and plant type.Finally,promising research directions of bioretention for improving stormwater runoff quality are predicted.
