摘　　要：选用成品桶装纯净水为研究对象,成品分别在下线6 h、12 h、24 h、48 h、96 h后进行菌落总数检测,并对其微生物类别进行鉴定,目的是对桶装纯净水中的微生物有针对性地进行预防和控制。结果表明,成品下线6 h后,检测样品时几乎没有微生物的存在,然而随着时间的延长,菌落总数明显的增多。分别对不同的菌落进行分离、纯化并进行鉴别,结果显示有细菌(主要是大肠杆菌)和真菌。The total bacterial count was detected and microorganism categories were identified in bottled purified water after online production for 6 h, 12 h, 24 h, 48 h, 96 h. The main detection purpose was to prevent and control microorganism in pure water process. Test results showed that total bacterial count of samples after online production for 6 h almost had no microorganisms, however, with the extension of time, the total number of colonies increased obviously. After separation, purification and identification of different colonies, the results showed that bacteria （mainly Escherichia coil） and fungi were founded.
