摘要
目的了解农村幼儿园饮用水卫生学状况,为预防饮水传染病提供依据。方法 2017年8月对青岛市即墨区农村幼儿园的饮水卫生状况进行调查,对幼儿园的饮用水进行了细菌总数、总大肠菌群、硝酸盐氮、氟化物监测。结果调查299家幼儿园的盛水容器,218家(72.91%)为不锈钢保温桶,均有盖。每周洗刷并消毒5次以上的仅有179家(59.86%),均用含氯消毒剂进行浸泡消毒。其他为电热壶兼用容器。有158家(52.84%)幼儿园,都是先烧开,然后用容器把开水接出来,再倒入保温桶中,待冷却后或不烫人后,再提供给孩子们喝。所采299家幼儿园的饮用水中,不合格43家,不合格项目均为细菌总数。总体合格率为85.62%。结论不当的饮水方式是造成细菌总数超标的原因。细菌总数是水质清洁度和净化效果的重要指标。
