摘　　要：根据大连市水功能区水质现状评价结果 ,选取达标率较低的复州河、大沙河作为研究对象,化学需氧量、氨氮为主要污染指标,选定相应的水质模型,设计参数,计算重点河流的水体纳污能力,并计算入河污染物的控制排放总量。结果表明:复州河水体纳污能力化学需氧量和氨氮分别为823.36t/a和40.55t/a,大沙河水体纳污能力化学需氧量和氨氮分别为2 021.67t/a和89.02t/a。According to the evaluation result of water quality situation in the water function area in Dalian City,Fuzhou River and Dasha River are selected as the research objects because of their low qualified rate.The chemical demand of oxygen,ammonia and nitrogen is the main index of pollution so that the total amount of pollutants’ limiting emissions into the rivers can be calculated.
