| 摘 要： | 受物理、化学、生物等多重因素的影响,城市降雨径流水质的模拟研究比较模糊。以TSS(总悬浮固体量)为例,利用SWMM的污染物模块及其土地利用模块、污染物累积模块和污染物冲刷模块进行城市雨水径流水质模拟;考虑了不同土地利用情况对污染物的累积及冲刷的影响,针对不同的降水量,利用EMC法(平均浓度法)以及指数方程法进行污染物的冲刷模拟,指数方程法的模拟精度大于EMC法的模拟精度,与监测值更接近。指数方程法的模拟结果表明:当降水量小于2.5mm时,其TSS冲刷量增长幅度较缓;而当降水量大于3.5mm时,其TSS冲刷量呈显著线性增加关系,从而表明,降水量较大的降水事件对于TSS的冲刷量影响更为显著。 |

| Abstract: | Due to influences of physical,chemical and ecological factors,simulation of the urban runoff quality is a very complex issue in the study of wet-weather flows and their environmental impacts.Taking total suspended solid(TSS) as an example,this paper simulated the building-up and washing-off TSS using the modules of pollutant,land use,build-up and wash-off of stormwater management model(SWMM).Different land uses were taken into consideration for analysis.The event mean concentration(EMC) and exponential func... |
| Keywords: | stormwater management model runoff quality total suspended solid non-point source pollution event mean concentration exponential function |
