【摘要】 通过建立复杂潮汐河网地区一维与二维耦合模型,分析了江浙来水对黄浦江三项主要水质指标COD、BOD5、NH3-N的影响,认为:(1)现状江浙来水水质下,黄浦江上游取水口松浦大桥断面,江浙来水是影响其水质的重要因素,对该断面的污染分担率为44％-64％;中游临江断面,江浙来水的污染分担率为27％-41％;中下游南市水厂断面, 江浙来水的污染分担率达16%-28％;下游杨浦大桥断面,江浙来水的污染分担率为 5％-14％。(2)现状来水水质下,松浦大桥取水口断面的预期水质目标是COD、BOD达到类水、NH3-N达到类水,如果NH3-N要达到类水,不改善江渐来水水质是不可能的。更多还原

【Abstract】 Firstly the coupled one-dimensional and two-dimensional model for complex tidal river network with different scale rivers was developed, then quantitative influence of Shanghai receiving water from neighboring Jiangsu and Zhejiang Provinces on water quality of the Huangpu River was analyzed. The following conclusions are drawn: (1) the current receiving water from neighboring provinces exerts key influence on the water quality of Songpu Bridge station of the upstream Huangpu River, which is also the important drinking water source place, the pollution contribution rate of receiving water reaches 44-64%; among other typical stations, the pollution contribution rate of receiving water to Linjiang station reaches 27-41%, the pollution contribution rate to Nanshi Water Plant station is about 16-28%, the pollution contribution rate to Yangpu Bridge Station is about 5-14%. (2) With the current receiving water from neighboring provinces, the suggested water quality amelioration object for the drinking water source station (Songpu Bridge station) is: COD、BOD5 reach class Ⅰ of national surface water quality standard; NH3-N reaches class Ⅲ of national surface water quality standard, for NH3-N, it will not reach class Ⅱ of national surface water quality standard unless the water quality of receiving water improves.更多还原
