摘要
目的：了解阳泉市平定县农村生活饮用水水质情况，对2009-2012年平定农村生活饮用水监测结果进行分析，为改善平定县农村生活饮用水的卫生质量提供依据。方法：每年在枯水期和丰水期分批采集水样，按照《生活饮用水标准检验方法》（ GB/T5750-2006）《生活饮用水卫生标准》进行检验和评价。结果：4年共检测农村生活饮用水484份，合格125份，总合格率为25．83％，不合格项目主要为浑浊度、总硬度、硫酸盐、氨氮、菌落总数、总大肠菌群。2009-2012年平定县生活饮用水合格率分别为：10．9％、21．43％、28．75％、34．46％，经统计学分析差异有统计学意义（χ2=27．45，P﹤0．05）；枯水期和丰水期合格率分别为34．3％、17．36％，经统计学分析差异有统计学意义（χ2=18．13，P﹤0．05）；出厂水和末梢水合格率分别为26．45％、25．21％，经统计学分析差异无统计学意义（χ2=0．09，P﹥0．05）。结论：平定县农村生活饮用水的总体合格率逐年提高，但总体合格率较低，因此，要加强农村生活饮用水的供水系统建设、监督管理、净化消毒工作，为农村生活饮用水安全提供保障。
Objective： To obtain some information about the rural drinking water quality in Pingding County, Yangquan City, from 2009 to 2012 with the further analysis of the monitoring results in order to provide a strong basis for the hygienic quality of rural drinking water. Method： Water samples were collected each year in the low water period and high water period to inspect and evaluate, in accordance with the “ standard examination methods for drinking water” （GB/T5750-2006） and ＂ the sanitary standard for drinking water ＂ Results： 484 parts of rural drinking water were detected during 4 years, of which 125 samples were qualified and the overall qualification rate was 25.83%. The unqualified items were mainly turbidity, total hardness, sulfate, ammonia nitrogen, total bacteria, total coliforms. From 2009 to 2012, qualified rates of drinking water in Pingding County were respectively： 10.9% ,21.43% ,28.75%, 34.46% ; there were statistically significant differences （ X^2 = 27.45, P 〈 0.05 ） ; in the low water period and high water period the qualified rates were respectively 34.3% , 17.36% ; There were statistical significant differences （X^2 = 18.13, P 〈0.05）; qualified rate of factory water and peripheral water were respectively 26.45%, 25.21%; There were no statistically significant differences （ X^2 = 0.09, P 〉 0.05 ）. Conclusion： The overall qualification rate of rural drinking water in Pingding County has been increasing year by year, though the overall qualified rate is low. Therefore, it is time to improve water supply system, strengthen the supervision and management of construction work and achieve the purification and disinfection to rural drinking water. Furthermore, the rural drinking water safety would be provided.
