| 摘 要： | 在论述双权重的基础上,建立了水质评价的模糊综合模型。通过监测总硬度、SO42-、Cl-、Cr6+、Pb、Fe等水质影响指标,计算了各指标的程度权重和因素权重,采用灰色模糊综合评价的方法评价了临涣矿区10个采样点的水质。研究结果表明:8个点属于IV类水,1个点属于V类水,1个点属于Ⅲ类水。评价结果为矿区废水处理方法的选择和资源化提供了依据,并为矿区水污染环境的治理提供了基础数据。

| Abstract: | Based on the double weights discussion,the fuzzy synthetic water quality evaluation model has established.Through water quality impact indices monitoring of total hardness,SO42-,Cl-,Cr6＋,Pb and Fe,degree weight and factor weight of each index have computed.Grey fuzzy synthetic evaluation has used in evaluation of water quality from 10 sampling sites in the Linhuan mine area.The result has demonstrated that,water from eight sites belong to Class IV,one Class V and one Class III.The evaluated result has provided basis for mine area waste water processing method selection and reclamation,also basic data for mine area water polluted environment harness. |
