摘要
生物滞留系统是一种有效的海绵城市的建设,可以有效地截留和去除城市雨水径流污染过程中的持久性有机污染物(POPs)。同时,POPs的积累也会对生物滞留系统中的生物产生毒性和抑制作用,甚至形成污染源向外扩散,从而影响其使用寿命,引起周边土壤以及地表水和地下水的污染问题。该研究分析了典型POPs在城市地表径流中的来源和特征以及在生物滞留系统中典型POPs的去除效果、影响因素、分布状况及其去除机理。指出生物滞留设施中POPs的积累、迁移、转化及修复是今后的主要研究方向。
Bioretention system is an effective construction for the sponge city,it can effectively intercept and remove POPs from urban stormwater runoff pollution(POPs). At the same time, the accumulation of POPs can also cause toxicity and inhibition to organisms in the bioretention system, forming a source of pollution, which affects its service life, causes pollution of surrounding soil and surface water and groundwater. The sources and characteristics of typical POPs in urban surface runoff,as well as removal effect, influencing factors, distribution and removal mechanism of typical POPs in bioretention system were analyzed, and it pointed out that the accumulation, migration, transformation and restoration of POPs in bioretention facilities are the main research directions in the future.
