顺德某学校饮用水微生物污染状况调查分析

为了解顺德某学校饮用水微生物卫生质量状况，随机在30个直饮水机的温水出口及6个桶装水饮水机的冷水出口抽取了饮用水进行检测。检测结果显示，30个直饮水机温水出口的细菌菌落总数、大肠茵群、霉菌和酵母茵合格率均为100．0％；6个桶装水饮水机出口冷水根据不同开封时间和清洗状况，均出现不同程度的污染。对3个常用一线品牌桶装水开封后保质期研究发现，桶装水开封后保质期为2～3天。建议为确保师生饮用水安全，应完善饮用水安全管理制度，对饮用水进行定期检测，并加强饮用水卫生安全知识教育。

Investigation and Analysis on Microbiological Pollution of Drinking Water in A School of Shunde

In order to survey the sanitary condition of drinking water in Shunde Polytechnic, samples of 30 direct drink- ing water dispensers and 6 barreled waters with drinking dispensers were tested. The testing result shows that the eligi- ble rate of Bacterial Colonies Number, Coli Group, Mold Colony and Yeast Colony of the 30 direct drinking water sam- ples are 100.0%. But 6 cold water fitting samples of barreled waters were contaminated to different degrees according to their open time and degree of cleanliness. Further study of quality guarantee period after opening of 3 brand barreled wa- ters shows that quality guarantee period after opening is 2 - 3 days. It is suggested that in order to guarantee the health of teachers and students, Water Safety Management system should be established, drinking water in the school should be tested at regular intervals, and knowledge on the safety of drinking water should be popularized.
