1) water quality classification
水质分级法
1.
Taking Hutuohe area of Shijiazhuang for example,this paper chooses NH+4,SO2-4,NO-3,NO-2,CN-and C6H5OH as evaluation factors,adopts the methods of Nemerow index,fuzzy mathematics and water quality classification to evaluate the water quality,and compares the research results.
以石家庄滹沱河地区为例,选择氨氮、硫酸根、硝酸根、亚硝酸根、氰化物、挥发性酚类(以苯酚计)6个评价指标,采用内梅罗指数法、模糊数学法以及水质分级法进行水质评价,并将评价结果进行对比研究,结果表明:内梅罗指数法过程简单、运算方便,但过于突出最大污染因子,未考虑权重因素;水质分级法没有考虑水质分级的模糊性,受最大浓度的指标因素影响较大,不能客观地反映水体的实际情况;模糊数学法用隶属函数描述水质分级界限,根据模糊聚类法确定因子权重,使评价结果更接近实际。
