| 中文摘要: |
| 以都匀市杨柳街河为研究对象，采用取样分析以及水质指数(WQI)与重金属污染评价指数(HEI)等方法对杨柳街河矿井水污染特征进行分析，并对其水质进行评价。研究结果显示，矿井水汇入杨柳街河流后，水体以呈淡黄色、铁锈色等及PH值低、SO42－、总硬度及TFe含量高为主要标志；研究区水质指数(WQI)与重金属污染评价指数(HEI)变化趋势相似，河流源头处水质级别为优、好，矿井水汇入后，水质变为差、不宜饮用，经过一系列治理措施后，水质级别变为好，但是整体水质仍劣于源头处。 |
| 英文摘要: |
| In this paper, Taking the Yangliujie river in Duyun city is taken as an example, it uses sampling analysis and water quality index (WQI) along with heavy metal pollution assessment index (HEI) to analyze the characteristics of mine water pollution in the Yangliujie river and evaluate its water quality. The results show that after mine water enters the Yangliujie river, the water body is primarily marked by its light yellow or rust color, low pH, high SO42-, total hardness, and TFe content; the changing tendency of the water quality index (WQI) and the heavy metal pollution evaluation index (HEI) is similar, the water quality at the river source is excellent and good. After the mine water inflow, the water quality becomes poor and unsuitable for drinking. After a series of treatment measures, the water quality level becomes good, but the overall water quality is still inferior to the source. |
