摘要
在泾河陕西段选取13个采样点,根据单因子评价法和模糊综合评价法,对水中4种污染指标(高锰酸盐指数(CODMN)、总氮N、总磷P、悬浮物(SS))的进行计算并分析得出,泾河整体水质较差,且注入渭河河段水质为V类,基本丧失水的使用功能,且泾河陕西段上游悬浮物含量过高,应采取相应控制对策尽快改善泾河水质.
Water samples from 13 points along the Jinghe river in Shaanxi province were collected.According to single factor evaluation method and fuzzy comprehensive evaluation,values of major pollutant indicators such as high permanganate index,total nitrogen,total phosphorus and suspended solids were estimated.It was found that the general water quality of the Jinghe river has become worse.Water flowing into Weihe river mainstream was found to be class V,which has become un-suitable for social and ecological utilizations.The concentration of suspended solids in Jinghe river upstream was very high.Some countermeasures should therefore be taken to control this serious pollutant in order to improve the water quality of the Jinghe river as soon as possible.
