摘要
课题组采用单因子指数法和综合污染指数法分析评价了2016—2022年萍水河三田断面水质动态特征。结果表明,研究期内萍水河19项水质指标均达到地表水环境质量Ⅲ类水标准;从单因子污染指数来看,高锰酸盐指数和COD较高,说明该断面主要的污染是有机污染;从综合污染指数来看,该断面的综合污染指数在0.3~0.5之间,2017年和2022年的综合污染指数较低,水质相对较好。
The characteristics of water quality in Santian section ofPingshui River from 2016 to 2022 were assessed by using Single Factor Index method and Composite Pollutant Index.The results showed that 19 water quality indicators of Pingshui River during the research had met the water standard of ll class of surface water environmental quality.From the perspective of Single Factor Index,the index of permanganate and COD are higher,which indicates that the organic contamination prevails this section.According to the Composite Pollutant Index,which range from 0.3 and 0.5,the water quality was relatively good especially in 2017 and 2022,when the index were lower.
