摘要
基于SWMM模型,利用GIS、RS及GPS技术构建滇池流域东南岸的非点源污染量化模型。结合排水系统的特点,划分子排水单元,并进行参数灵敏度分析、率定及模型验证,完成模型的建立,模拟昆明主城城市降雨径流污染。进行模型的设计降雨重现期,对环湖截污系统各污水处理厂相应的干渠汇水断面来水的水质水量过程进行模拟,并对滇池环湖截污系统进行效能分析。
The model of SWMM was built to quantify the non -point source pollution in the south -eastern area of the Dianchi - lake basin using GIS, RS and GPS technology. Based on the characteristics of the drainage system, the drainage units were delineated. The sensitivity analysis of the parameters was conducted as well as the verification and the calibration. The modal was built up to simulate the rainfall pollution in the downtown area of Kunming. Through resetting the rainfall reappearing period of the model, the water volume and water quality of the drainage system connecting to all wastewater treatment plants were simulated to analyze the efficiency of the lakeside intercepting sewage system.
