摘　　要：目的了解宁夏山区某县农村窖水水质卫生学状况,为改善窖水水质提供实验室依据。方法采用分层随机抽样的方法,按不同经济状况,选取宁夏山区某县以窖水为饮用水的两个乡镇,随机采集窖水水样,参照生活饮用水卫生标准(GB5749-2006),对所检测指标进行分析。结果总硬度没有超标,溶解性总固体超标率为4.5%;锰超标率为3.0%;铁超标率为56.7%;pH值超标率为7.5%;氨氮超标率为29.9%;COD超标率为8.96%。两种不同径流来源窖水超标率比较,差异无统计学意义。结论宁夏山区某县农村窖水部分感官指标和理化指标都有不同程度的超标,应加强宣传教育,提高农民的饮水安全意识,仍需加大农村的改水力度。Objective To explore the pit water quality in the rural areas of Pengyang county in Ningxia Province and to provide experimental basis for improve water quality. Methods stratification sampling method was used, according to economic states, selecting water sample from two towns where the residents regard pit water as main drinking water randomly. Sensory index were measured in situ. Another were taken into experiment, determining general chemical index, compared with the national standards, to assess the pit water hygiene quality. Results comparing with the National Hygienic Standard for Drinking Water （GB5749 -2006）, the indexes that exceeded the related standard limit were total dissolved solids, Mn, Fe, pH, ammonia nitrogen and chemical oxygen demand（COD）, The over standard rates were 4.5% ,3.0% ,56.7% ,7.5% ,29.9% them. Conclusion the quality of pit water sample in the rural areas of Pengyang county in Ningxia Province exceeds standard in varying degrees. Health education should be strengthened in order to improve awareness for drinking safety. Water improvement in the rural areas should be enhanced in the future.
