摘要
针对城市内涝积水及径流污染,基于地理信息系统GIS和SWMM平台建立雨水管网模型,对比分析布设LID措施前后降雨径流、节点积水、管道荷载及排放污染物负荷,研究LID措施水量水质调控效果。结果表明,LID措施削减径流量37.2%、减少节点积水量99.4%、降低管道充满度、削减排放污染物负荷。LID模式能够调控降雨径流、削减污染物负荷,缓解节点溢流积水,降低管网运行荷载,降低内涝积水和面源污染风险,具有良好的水量和水质调控效果。
Based on the GIS and SWMM platforms of GIS and SWMM,the rainwater pipe network model is built to compare and analyze the rainfall runoff,node water logging,pipeline load and pollutant load discharge before and after the LID measures are taken. The effect of LID measures on water quantity and quality are studied. The results show that LID measures have reduced runoff by 37.2%,reduced node water accumulation by 99.4%,reduced pipeline fullness,and reduced pollutant loads. The LID model can regulate rainfall runoff,reduce pollutant load,relieve node overflow water,reduce pipe networks operating load,reduce the risk of internal water and non-point source pollution,and has good water and water quality regulation effects.
