摘　　要：[目的]了解元江县农村饮水安全工程水质卫生状况,为改善农村饮水安全工程水质卫生质量提供科学依据。[方法]对2008-2013年农村饮水监测结果进行分析,每年的枯水期和丰水期采集出厂水和末梢水各1份水样,按照GB/T5750-2006《生活饮用水标准检验方法》进行检测,按照GB5749-2006《生活饮用水卫生标准》进行评价。[结果]6年共检测农村生活饮用水824份,合格147份,总合格率为17.84%,不合格项目主要为浑浊度、肉眼可见物、锌、菌落总数、总大肠菌群、耐热大肠菌群和大肠埃希氏菌指标。2008-2013年水样合格率分别为12.05%、12.03%、20.71%、23.13%、24.38%、7.50%,基本呈逐年上升趋势(χ2=18.862,P<0.05)。枯水期水质合格率高于丰水期水质,出厂水与末梢水的合格率有显著性差异。[结论]元江县农村饮水安全工程水质总体状况较好,未发现高氟、高砷水,苦咸水的现象。总合格率偏低,主要是受微生物污染严重,水质卫生状况较差。应加强农村饮水安全工程点的监督管理,并对水质进行有效的净化消毒,确保农村生活饮用水卫生安全。Objective To understand the sanitary conditions of water quality of rural drinking water safety project（RDWSP） in Yuanjiang county, so as to provide scientific basis for improving the quality of drinking water. Methods It analyzed the monitoring results of rural drinking water from 2008 to 2013. Detected a sample of treated water and tap water Kan were collected respectively in low-water seasons and high-water seasons each year according to “Standard examination methods for drinking water＆quot;” GB / T 5750- 2006）, and evaluated in accordance with“Standards for drinking water quality”（ GB 5749-2006）. Results A total of 824 rural drinking water samples were tested in 6 years. Among them, 147 samples were qualified, with the qualified rate of 17.84%. The major unqualified indicators were turbidity, visible impurity, zinc, total bacteria colony, total coliform bacteria, thermotolerant coliform bacteria and escherichia coli index. The qualified rate was 12.05%, 12.03%, 20.71%, 23.13%, 24.38%, 7.5%from 2008 to 2013, showed mainly increasing trend year after year. Quality of water in low-water seasons was better than that in high-water seasons. Striking differences could be observed between the qualified rate of treated water and tap water. Conclusions The water quality of RDWSP in Yuanjiang county has a acceptable condition. There is no sign of high fluoride water, high arsenic water and brackish water. Total YIELD was low, and water quality sanitary conditions was poor since of polluted by microbial contamination. It need to strengthen supervision to the sanitary and safety of drinking water of RDWSP, insure safety of drinking water of RDWSP.
