【摘要】 目的分析南昌市农村地区饮用水安全工程水质卫生状况,为行政部门制定干预措施提供科学依据。方法分别于2009年枯水期、丰水期采集水样,按照标准方法进行检测、评价、分析。结果超标率较高的指标分别为总大肠菌群(49.71%)、耐热大肠菌群(45.35%)及菌落总数(8.43%)。以井水为源水的水样总大肠菌群、耐热大肠菌群超标率均高于以江河水为水源的水样(P<0.05)。结论我市部分农村地区饮用水卫生仍然存在较多问题,尤其是微生物污染严重,消毒工作未有效开展是其主要原因。更多还原

【Abstract】 Objective To analyze the sanitary condition of drinking water in some rural areas of Nanchang and provide scientific evidence for the preventive measures.Methods water were sampled in dry season and wet season respectively in 2009,and were tested evaluated and analysed according to standard methods.Results The over-limit ratio of the total coliforms (49.71%),thermotolerant coliforms(45.35%) and bacteria count(8.43%) were higher than others. The total coliforms group and thermotolerant coliforms of water samples from shallow well and deep well were higher than water samples from rivers(P<0.05).Conclusion There are many problems of drinking water quality in rural areas.Microbial contamination is especially serious because of uneffective disinfection.更多还原
