Application model in mine water quality evaluation based on double weight
Proceedings of the 3rd International Conference on Environmental Technology and Knowledge Transfer（2010）
Abstract
Based on the illustration of double weight, fuzzy comprehensive evaluation model of water quality was established. Degree weight and factors weight were calculated, after monitoring the water influence factors of total hardness, SO4 2-, Cl-, Cr6+ and Pb. Water quality of 10 sampling points were evaluated by the method of gray fuzzy comprehensive evaluation in Linghuan mine area. The evaluation results indicated that the water quality of 8 sampling points was V, the other 2 was V and III.
