摘要

摘要: 以天津市某海绵型建筑小区为研究对象,采用在线监测与模型模拟相结合的方法,开展小区尺度海绵化改造对径流水量水质效果评估的量化研究。构建暴雨雨洪管理模型,利用实测降雨、水量、水质数据进行模型关键参数的率定与验证,在设计降雨和实际场次降雨、多年连续降雨情景下,模拟分析海绵化改造对径流总量、径流峰值、径流污染的控制效果及差异。结果表明,海绵型建筑小区在2~10年一遇设计降雨重现期下,径流总量控制率为64.43%~74.10%,径流体积削减率为31.27%~40.09%,监测排口处径流峰值削减率为40.57%~41.40%。在55场实际降雨情景下,径流总量控制率为58.29%~100.00%,径流污染削减率为40.93%~83.05%。同时,总降雨量、最大小时降雨量是影响径流总量、径流污染控制效果最主要的降雨特征,存在较强的负相关(P<0.01)。多年连续降雨情景下,年径流总量控制率为78.61%,年径流体积削减率为37.18%,年径流污染削减率为45.16%。该研究成果可为科学定量评估海绵型建筑小区径流控制效果提供参考。

Abstract: This study took a sponge reconstruction community in Tianjin as the research object, and used a combination of online monitoring and model simulation to conduct a quantitative evaluation of the control effect of sponge construction on runoff and water quality at the community scale. We built a stormwater management model, calibrated, and verified the key parameters of the model using the measured rainfall, water volume and water quality data, and simulated and analyzed the control effect and difference of sponge transformation on the total runoff, runoff peak value, and runoff pollution under the scenarios of design rainfall, actual field rainfall, and multi-year continuous rainfall. The results showed the total runoff volume control rate was 64.43% to 74.10%, the runoff volume reduction rate was 31.27% to 40.09% for the sponge community, and the peak flow reduction rate was 40.57% to 41.40% for the monitored area with different return periods. The total runoff volume control rate was 58.29% to 100.00%, and the runoff pollution reduction rate was 40.93% to 83.05% under 55 rainfall events. Total rainfall and maximum hourly rainfall were the most important characteristics affecting the efficiencies of runoff control and non-point source pollution reduction, with a strong negative correlation (P<0.01). The total runoff volume control rate was 78.61%, the runoff volume reduction rate was 37.18%, and the runoff pollution reduction rate was 45.16% with years of continuous rainfall. The results provided a reference for evaluating the effects of runoff control and non-point source pollution reduction at a community scale after the sponge reconstruction.
