摘要:
为了控制管道沉积物在径流雨水冲刷下对受纳水体造成的污染，采用雨水调蓄池截流初期雨水来削减高比例的降雨径流污染负荷，利用SWMM软件模拟研究了末端集中式和沿线分散式初雨调蓄池对污染物的控制效果。结果表明，4座沿线分散式初雨调蓄池能够降低沿线管道流量，减少管道沉积物冲刷和初期雨水溢流现象，相较于同容积下的1座末端集中式初雨调蓄池，在两场降雨中对悬浮物的平均削减率由68.58%提升至78.68%，在实际单块用地面积不足的情况下，采用分散式小面积调蓄池能够获得更好的环境效益。
Abstract:
To control the sewer sediment pollution to receiving water caused by runoff flushing, rainwater storage tanks were used to intercept the initial rainwater to reduce its high proportion of pollution load, and SWMM software was used to simulate the pollutants control effects of the terminal centralized and local distributed initial rainwater storage tanks. The results showed that the four local distributed initial rainwater storage tanks could reduce the pipeline flow, sewer sediment erosion and initial rainwater overflow. Compared with one terminal centralized initial rainwater storage tank with the same volume, the pollutants reduction rate increased from 68.58% to 78.68%. When the area of single land is insufficient, the local distributed storage tank with small footprint area can obtain better environmental benefits.
