摘 要:目的了解居民饮用桶装水卫生状况。方法采用调查问卷及整群抽样方法对居民桶装饮用水细菌和理化指标检测。结果居民对饮水机消毒重视不够,从未消毒占到66.7%;细菌总数超标严重,桶装水细菌总数合格率为42.1%,最高超标15.3倍。净水器净化后的自来水细菌总数合格率为57.7%,最高超标12.9倍;桶装矿泉水弱碱性偏多,耗氧量合格率100%,亚硝酸盐合格率偏低,为80.7%。净水器净化后的自来水主要卫生问题是电导率及亚硝酸盐超标,其电导率均值是桶装矿泉水1.9倍,亚硝酸盐是桶装矿泉水5.3倍,净水器净化后的自来水呈弱碱性偏多,耗氧量合格率76.9%。结论桶装饮用水存在许多卫生质量问题。Objective To understand the hygiene status of family drinking water. Methods A clustered sampling method was used to select the samples, and a questionnaire survey, and physical and chemical inspections were performed. Results Up to 66.7% watering was never disinfected, which meant most of the citizen ignored the hygiene of the drinking water. The qualification rates of the total number of bacteria in bucket mineral water and cleaner water were only 42.1% and 57. 7%, respectively. The highest total number of bacteria were 15.3 and 12.9 times of the standard in the above two kinds of water. Most of the bucket mineral water and cleaner water were alkalescent. The percentages of pass of oxygen-consumption of the bucket mineral water and deaner water were 100% and 76.9%, respectively. The percent of pass of nitrite of the mineral water was 80.7 % and the nitrite of the cleaner water was 5.3 times of that of the mineral water. Conclusions There were many hygiene quality problems in the packing drinking water.
