摘　　要：目的通过对烟台市近年来农村饮用水卫生监测,了解农村饮用水水质变化趋势,为改善农村饮用水水质提供可靠的科学依据。方法 2012-2015年,对烟台农村地区生活饮用水按照《生活饮用水卫生标准》（GB5749-2006）常规指标进行检测,检测频率：枯、丰水期各1次。结果 2012-2015年共检测2 348份水样,总合格率为30.58%。2012-2015年烟台农村饮用水各年度合格率差异无统计学意义（χ^2=7.361,P=0.061）;枯水期水质合格率显著高于丰水期,差异有统计学意义（χ^2=18.981,P〈0.001）;出厂水、末梢水水样检测合格率差异无统计学意义（χ^2=0.289,P=0.591）;不同水处理方式的水质合格率不同,差异有统计意义（χ^2=557.606,P〈0.001）,其中以水质的完全处理合格率最高,仅消毒次之,仅沉淀过滤和未处理的水质合格率最低。结论烟台农村生活饮用水合格率偏低,毒理学指标、细菌学指标是影响本市农村饮水水质的重要因素。丰水期水质质量较枯水期差,应在丰水期加强水源保护、水质处理。进行饮用水的消毒处理是提高饮水质量的关键。Objective Through monitoring on rural drinking water in recent years in Yantai, the aim of this study was to understand the changing trend of water quality of rural drinking, in order to provide reliable scientific basis to improve the quality of the drinking water. Methods From 2012 to 2015, the sample was monitored in accordance with ＂drinking water health standards＂ （GB5749-2006） . The frequency of the monitor was twice a year, one in the wet season, one in the dry season. Results From 2012 to 2015, 2348 water samples were detected. And the total passing rate was 30.58%. The difference for the passing rates was not statistically significant （E2 =7.361 ,P=0.061）. The difference for the dry and the wet season＇s passing rate was statistically significant （X2 =18.981 ,P〈O.OO1）. The difference for different types of water＇s passing rate was not statistically significant （E2 =0.289,P=0.591）. Different ways for water treatment had different passing rate of water, and the difference was statistically significant （E2 =557.606,P〈0.001 ）. The passing rate of ＂fully processed＂ water was the highest, followed by the ＂ only disinfection＂ water. Unfortunately, the ＂only filtration and sedimentation＂ and the ＂ untreated＂ water had the lowest passing rate. Conclusion The passing rate of Yantai rural drinking water was low, and the toxicology indicators, microbiological indicators were important factors affecting the city＇s drinking water quality in rural areas. In the wet season, the passing rate of water was lower, effective water treatment and conservation were urgently needed in the wet season. To improve the quality of drinking water in Yantai, disinfection of drinking water is the key.
