摘　　要：目的了解北京市丰台区饮用水自备井的供水情况、水质卫生状况,为加强水质管理和改进提供依据。方法采用统一设计的调查表对自备井进行卫生学调查并采集水样,按照GB/T 5750-2006《生活饮用水标准检验方法》进行检验,用GB 5749-2006《生活饮用水卫生标准》对水质状况进行评价。结果共调查119口自备井,采集水样116件,合格16件,总体合格率为13.8%。检测水质的27项指标中,7项出现超标情况,分别为锌、浑浊度、氯化物、硫酸盐、硒、总硬度和硝酸盐,合格率分别为98.3%、97.4%、94.0%、89.7%、89.7%、17.2%和16.4%。87.4%的自备井有泵房,84.0%的自备井有卫生管理制度,66.4%的管网从未更新,21.0%的自备井有消毒处理。自备井的建井时间、井深是水质的可能影响因素。结论丰台区自备井水质部分指标未达到国家规定的饮水标准,应加强管理,采取针对性的改善措施。[Objective]To investigate the water supply situation and sanitary condition of self-contained draw-wells in Fengtai District of Beijing,provide basis for strengthening management and improving water quality.[Methods]The hygienic investigation of rural self-contained draw-wells was conducted by the unified questionnaire.Water samples were analyzed according to the National standard determination methods for drinking water quality（GB/T 5750-2006）.The assessment was made with the National hygienic standard for drinking water Quality（GB 5749-2006）.[Results]A total of 119 self-contained draw-wells and 116 water samples were investigated,and 16 samples were qualified with the qualified rate of 13.8%.Among the27 indicators of water quality,7 indicators exceeded the standard,which was zinc,turbidity,chloride,sulfate,selenium,total hardness and nitrate,and the qualified rate was 98.3%,97.4%,94.0%,89.7%,89.7%,17.2% and 16.4%,respectively.87.4% of self-contained draw-wells had pumping station,84.0% had health management system.66.4% of the pipe network had never been updated and 21.0% of wells were equipped with disinfection device.Drinking water quality was related to the construction time and depth of well.[Conclusion]The detection results of some indicators of self-contained draw-wells in Fengtai District do not meet the national standard for drinking water.It is necessary to strengthen the management and take the targeted improvement measures.
