摘要


    

The water samples in Dajing abandoned lead- zinc mining area and ditch are collected in Shuicheng, Guizhou Province. Taking Surface Water Environment Quality StandardGB 3838 -2002 as the evaluation standard, fuzzy synthetic evaluation and single water quality parameter assessment are used to assess the heavy metal pollution grade of the water. Conclusions of fuzzy synthetic evaluation show that the membership degrees of sampling point W1, W2, W3 corresponding to the Vclass water are 0.107, 0. 511, 0.502, respectively. According to the rule of membership degree maximum, water quality at each sampling point is Vclass water, a serious pollution degree. Conclusions of single water quality parameter assessment show that water quality monitoring points of W1, W2, W3 exhibit a serious Cd pollution, higher than the standard value 9.7, 1.03, 0.92 respectively.
