摘　　要：利用加权平均值和多个排放量计算方法对入河排污口水环境展开研究,采集各行政区的入河排污口的污水、化学需氧量、氨氮数据,得出结论:A行政区、B行政区、C行政区污染最重,污水排放量均已达到了3.2亿吨以上,E行政区、F行政区、D行政区的年污水排放量相对较少,均在0.5亿吨以上。选取近五年入河排污口污染物排放数据,结果表明,河底污染、河流内部水的流动力、入河排污口与污水管网设置不合理是造成入河排污口水环境污染的主要原因,并提出从污水管网建设、管理策略、监督体系等多个方面进行综合治理,改善水环境质量。Using weighted average and multiple emission calculation methods,the water environment of the river discharge outlet was studied.Data on sewage,chemical oxygen demand,and ammonia nitrogen were collected from the river discharge outlets in various administrative regions.The conclusion was drawn that administrative regions A,B,and C had the heaviest pollution,with sewage discharge exceeding 320 million tons.The annual sewage discharge of administrative regions E,F,and D was relatively small,all exceeding 50 million tons.Selecting the pollutant discharge data from the river discharge outlets in the past five years,the results show that bottom pollution,the flow force of water inside the river,and the unreasonable setting of the discharge outlets and sewage pipe network are the main reasons for water environmental pollution at the river discharge outlets.It is proposed to comprehensively control the water environment quality from multiple aspects such as sewage pipe network construction,management strategies,and supervision systems.
