多种水质评价方法在喀左地区的应用分析

Application Analysis of Various Water Quality Evaluation Methods in Kazuo County

采用单因子指数评价方法、综合污染指数法、模糊综合评判法、主成分分析法以及水污染指数法等对于辽宁省喀左县第二牤牛河地区水质进行了评价与分析。其中,采用较适宜的水质评价分析方法,可以更好地掌握当地的水质情况,进一步为当地水环境管理提供依据。结果表明,综合污染指数法更能简洁直观地体现出当地的水质情况及污染物含量。其中,左岸地下水的溶解氧为26.55%,镉含量为0.49%,汞含量为0.64%;右岸地下水的溶解氧为26.65%,镉含量为0.49%,汞含量为0.64%;上游地表水的溶解氧为25.55%,镉含量为0.59%,汞含量为0.74%;下游地表水的溶解氧为25.56%,镉含量为0.59%,汞含量为0.74%。

The water quality of the second Muniu River area in Kazuo County,Liaoning Province was evaluated and analyzed by single factor index evaluation method,comprehensive pollution index method,fuzzy comprehensive evaluation method,principal component analysis method and water pollution index method.Appropriate water quality evaluation and analysis methods are used to better grasp the local water quality and further provide basis for local water environment management.The results show that the principal component analysis method can more concisely and intuitively reflect the local water quality.Among them,the dissolved oxygen in the groundwater on the left bank is 26.55%;the cadmium content is 0.49%,and the mercury content is 0.64%;the dissolved oxygen in the groundwater on the right bank is 26.65%;the cadmium content is 0.49,and the mercury content is 0.64%;the dissolved oxygen in the upstream surface water is 25.55%;cadmium content is 0.59%;mercury content is 0.74%;dissolved oxygen in downstream surface water is 25.56%;cadmium content is 0.59%and mercury content is 0.74%.
