摘　　要：目的了解新干县农村饮用水卫生状况及其影响因素,为农村实现安全供水提供科学依据。方法对2012-2014年新干县的农村生活饮用水水质监测点分别进行丰水期和枯水期水样的采集与检测。结果共监测水样730份,合格172份,合格率为23.56%,不同年度的枯水期水质合格率均明显高于丰水期(P<0.05)。该县农村生活饮用水以分散式供水为主,集中式供水水质合格率及微生物指标合格率均高于分散式供水(P<0.05),但丰水期和枯水期两种供水方式的水质合格率差异均无统计学意义(P>0.05)。感观性状、一般化学指标、毒理学指标、微生物指标水样监测合格率分别为94.11%、83.29%、100.00%、29.59%,微生物指标合格率低是影响水质的主要因素。结论微生物污染是新干县农村生活饮用水的主要卫生问题,加强该县农村饮用水的消毒显得尤为重要。Objective To understand the hygiene status and influencing factors of rural drinking water in Xingan county,and provide the scientific basis for the realization of safe water supply in rural areas. Methods During 2012 -2014, the wet and dry seasons water samples were collected and detected from the rural drinking water quality monitoring stations in Xingan county. Results A total of 730 water samples were detected,while 172 samples were qualified,and the percent of the pass was 23.56%. The qualified rate of water quality in dry seasons was significantly higher than that in wet seasons in different years（ P 〈 0.05 ） . Drinking water in rural areas of the county was dominated by decentralized water supply. The qualified rates of centralized water supply and the microbial index were higher than that of the decentralized water supply （ P 〈 0.05 ） , but the qualified rates in wet and dry seasons of two water supply were not statistically significant （ P 〉 0.05 ）. The water monitoring qualified rates of sensory properties, general chemical indicators,toxicological indexes, and microbial indicators were 94. 11% , 83.92% ,100% and 29.59% ,respectively. What＇s more, the low qualified rate of microbial indicators was the main factor affecting water quality. Conclusion Microbial contamination is a major health problem of the rural drinking water in Xingan county, and it is very important to strengthen the disinfection of drinking water in rural areas.
