摘要
以深圳市光明新区为例,运用SWMM模型研究了生物滞留设施、透水沥青道路、透水铺装三种LID设施对区域内道路综合径流总量和污染负荷总量控制效果的影响中7个设计参数的优化,模型中水文水力、水质参数通过典型降雨过程进行率定。结果表明,E_(NS)、R^2值基本在0.77和0.80以上,SWMM模型模拟与实测水量水质过程趋势线基本一致,精度较好;7个设计参数中,D_A和D_C对径流总量和污染负荷总量控制呈负相关,其余参数呈正相关,且影响最大是D_C;B_H、S_(T1)和S_(T2)的设计优化值分别为0.15~0.3、0.6~0.8、0.5~0.7m,DC的设计优化值为0.5~1.5,H_A和D_A应在10%范围内予以优化。
This study presents an application of SWMM model in evaluating and optimizing seven design parameters of OGFC,porous pavement and bioretention for the influence of urban road runoff volume and pollution load control effect in Guangming New District of Shenzhen City.The values of calibration parameters in hydrology and hydraulic,water quality of the model were obtained from the typical monitored storm events.In this SWMM model,based on the findings,the simulated runoff volume and pollutant concentration were well matched with the measured for ENSand R-2 value of 0.77and0.80,respectively.Among seven design parameters,D_A and D_C were negatively correlated,while the remaining parameters were positively correlated,and D_C was the most influential parameter.The design optimization values of BH,ST1 and ST2 for bioretention,DC were 0.15-0.3m,0.6-0.8mand 0.5-0.7m,0.5-1.5,respectively.H_A and D_A were optimized in the range of 10%.
