摘　　要：通过对苏州X水厂的出厂水静态水质、配水管网的水质分析检测,并采用两种培养基分别检测水中菌落总数,考察了苏州市配水管网中菌落总数分布情况。结果表明采用R2A培养基及较长的培养时间得到的菌落总数,能较好地反映饮用水中微生物的水平,也能表达饮用水中的游离余氯与菌落总数之间呈较为明显的负指数相关。The distribution of total bacterial count in drinking water in Suzhou was investigated by static water quality analysis of finished water in Suzhou X waterworks. The result shows that total bacterial count got from R2A medium with longer culture time can reflect the real microbial growth level in drinking water, and there is a significant negative exponential correlation between free residual chlorine and total bacterial count in drinking water.
