为促进岳阳市南湖的开发建设与水环境保护协调发展,以南湖水环境监测资料为依据,利用有关数学模式南湖污染源与水质进行了评价,结果表明,影响南湖水质的主要污染源为城市生活污水,主要污染物分别为总磷,总氮,CODcr,BOD5,湖南水质呈现富营养化与有机物污染,处于重度污染水平,已达不到特殊保护水域功能要求,据此提出南湖水环境保护对策建议。
Based on the water environmental survey of South Lake in Yueyang, the pollution source and quality of water were evaluated by using mathematics models.The results show that the major source affecting water quality is this city's sewage waste; the major pollutants are TP,TN,CODcr,BOD 5;there is an organic pollution and eutrophication in South Lake.Heavily polluted, it has lost the function of special protected waters.Therefore, the protective countermeasures are put forward.
