摘要
根据济源市浅层地下水具有代表性的十眼监测井的2011年、2015年的水质测试数据,参照《地下水水质标准》(DZ/T 0290-2015)对地下水水质进行单项指标对比分析,并采用内梅罗指数法对其进行综合评价,分析济源市浅层地下水水质变化趋势,得出影响济源市浅层地下水水质的主要因素为总硬度、硝酸盐、硫酸盐、溶解性总固体、亚硝酸盐,同时针对济源市地形地貌、水文地质条件等综合特点找出造成水质污染的原因,并提出防治措施及建议,对地下水保护工作具有指导意义。
According to the water quality monitoring data of 10 representative shallow groundwater wells in Jiyuan City in 2011 and 2015, the groundwater quality was compared with the groundwater quality standard(DZ/T 0290-2015) and was evaluated by Nemerow comprehensive index method. The paper analyzed the changing trend of shallow groundwater quality in Jiyuan. The main affecting factors of shallow groundwater quality in Jiyuan are total hardness, nitrate, sulfate, dissolved total solids and nitrite. The causes of water quality pollution were found out according to topography condition, hydrogeological condition, etc, and the prevention measures and suggestions for groundwater protection were put forward. The study has guiding significance for the future groundwater protection.
