摘要
基于倭肯河2020-2021年逐月实测数据,采用4个监测断面的6项水质指标,应用多元统计方法,分析倭肯河水质时空分布特征,解析污染物来源,利用CCME-WQI对水质健康进行综合评价。结果表明,倭肯河水质时间聚类为枯水期(11-1月份)、平水期(2-6月份)、丰水期(7-10月份),3个时段主要污染来源分别是内源释放和工业、牲畜养殖废水排放等点源污染,生活污水和工业废水,农业面源污染;水质时空分布差异的主要影响因子是降雨、地表径流和点源污染;整个倭肯河流域CCME-WQI值在84.85~97.19,水质质量为优良。
Based on the monthly measured data from 2020 to 2021,6 water quality indexes of 4 monitoring sections were adopted to analyze the spatio-temporal distribution characteristics of water quality,analyze the source of pollutants and comprehensively evaluate water quality health using CCME-WQI.The results show that the water quality of the Woken river is time-classified into dry season(November-January),medial season(February-June),plentiful season(July-October).The main pollution sources in the three periods are endogenous release,point source pollution such as industrial and livestock breeding wastewater discharge,domestic and industrial wastewater,and agricultural non-point source pollution.The main influencing factors of spatio-temporal distribution difference of water quality are rainfall,surface runoff and point source pollution.CCME-WQI values are 84.85~97.19 in the whole Woken river basin,and the water quality is excellent.
