扬州城市饮用水水源地的水质安全评价研究

Research on Water Quality Safety Evaluation of Urban Drinking Water Source Area in Yangzhou

以扬州市10个城市饮用水水源地的水质为研究对象,基于扬州市生态环境局2020年水环境质量月报和现场取样监测,本文采用层次分析法(AHP),从理化指标层面出发,构建了水质类别、一般污染状况、非一般污染状况和富营养化状况四类评价指标,运用单因子指数法和内梅罗综合指数法进行评价,根据这四类评价指标对人体健康的影响赋予权重系数,结合最终结果对水质安全进行分析与评价。

Taking the water quality of drinking water sources in 10 cities in Yangzhou City as the research object,based on the 2020 monthly water environment quality report and on-site sampling monitoring by the Yangzhou Ecological Environment Bureau,this paper adopts the analytic hierarchy process(AHP),and constructs four types of evaluation indicators for water quality,general pollution,non-general pollution,and eutrophication by starting from the physical and chemical indicators,and uses single factor index method and Nemerow composite index method for evaluation,and assigns weight coefficients based on the impact of these four types of evaluation indicators on human health,and combines the final results to analyze and evaluate water quality safety.
