摘要
监测了安阳县饮用水源地珍珠泉、濮阳水泥厂、水冶炼铁厂和安阳县一中4个监测点地下水的11个水质指标,分析了各监测点水质指标的污染情况,评价了各监测点的水质等级,并分析了安阳县饮用水源地地下水水质年际变化规律。研究结果表明,安阳县地下水中总硬度和硝酸盐氮为重度污染,硫酸盐为中度污染,氰化物和亚硝酸盐为轻微污染。除总硬度和硝酸盐氮明显偏高外,其他水质指标均能达到III类标准。与2012年相比,2013年安阳县饮用水源地地下水质整体上趋于好转。
11 groundwater quality indexes of Zhenzhu Fountain,Puyang Cement Plant,Shuiye Iron Works,and Anyang No.1 Middle School were detected,pollution of water quality indexes was analyzed,water quality level was assessed,and the annual changes of groundwater water quality was analyzed in Anyang County.The results showed that total hardness and nitrate nitrogen pollute seriously,sulphate pollutes intermediately,and prussiate and nitrite pollute slightly.Other water quality index can reach level Ⅲ except total hardness and nitrate nitrogen.In contrast to 2012,groundwater quality of 2013 of drinking water sources tend to improve in Anyang County.
