摘要
以无锡环城古运河及其周边区域为研究对象,基于SWMM研究不同重现期设计暴雨情境下,距离河道不同距离(100~300m)缓冲区布设LID措施后的面源污染控制效果。结果表明,LID措施对污染物具有较好的去除效果,可以有效降低入河面源污染,改善河流水质。
In this paper,the ancient canal around Wuxi and its surrounding areas are taken as the research area.Based on SWMM,the control effect of LID measures on non-point source pollution is studied under different return period design rainstorm scenarios and different buffer areas(distance from 100~300m)from the river.The results prove that LID facilities have a good removal effect on pollutants,which can effectively reduce the non-point source pollution into the river and improve the river water quality.
