莱芜区上王庄村水文地质参数计算及地下水水质评价

Calculation of Hydrogeological Parameters and Evaluation of Groundwater Quality in Shangwangzhuang Village,Laiwu District

为解决莱芜区地下水开采与使用,水文地质参数与地下水水质是亟待解决的问题.以莱芜区上王庄村为例,通过单孔稳定流抽水试验计算含水层关键水文地质参数——渗透系数K与影响半径R,并采用单因子评价法、综合指数F值评分法和内梅罗综合指数法等对地下水水质进行评价.结果表明:莱芜区上王庄村渗透系数为2.22 m/d,影响半径为120.39 m;不同评价方法对地下水水质评价结果一致,即上王庄村地下水属Ⅴ类水、极差水或差水,不适宜作为居民直接饮用水源.

Hydrogeological parameters and groundwater quality are urgent problems to solve the exploitation and use of groundwater in Laiwu District.Taking Shangwangzhuang Village in Laiwu District as an example,the key hydrogeological parameters of aquifer-permeability coefficient K and influence radius R were calculated through single-hole steady flow pumping test.The groundwater quality was evaluated by single factor evaluation method,comprehensive index F score method and Nemerow comprehensive index method.The results show that the permeability coefficient of Shangwangzhuang Village in Laiwu District is 2.22 m/d,and the influence radius is 120.39 m.The groundwater quality evaluation results of different evaluation methods are consistent,that is,the groundwater of Shangwangzhuang Village is classified as CategoryⅤ,extremely poor or poor water,which is not suitable for direct drinking.
