摘要
自来水中人肠道病毒的存在已引起人们极大的关切和忧虑。本文报道了武汉东湖水和以东湖为水源的自来水中病毒和指示细菌的存在水平。水源水经过预加氯消毒、絮凝沉淀、砂滤和最后加氯消毒处理而成的自来水中细菌总数检测范围是41—500/升,总大肠菌是2—13/升、粪大肠菌为0—4/升、大肠菌噬菌体是0—13.6PFU/升,平均2.48PFU/升,肠道病毒为0—78PFU/升,平均为6.7PFU/升。水源水经制水工艺处理去除指示细菌、大肠菌噬菌体和肠道病毒的效率分别为97.95—99.99％,90.63％和53.18％。这种结果说明自来水制水工艺能有效地降低指示细菌,大肠菌噬菌体,而去除肠道病毒效率较低,揭示肠道病毒对环境压专的耐受性明显地比指示细菌强。

Abstract
The presence of any pathogenic viruses in tap water has always been considered a potential public health concern. This study reports the presence levels of viruses and indicator bacteria in the water body of East Lake and treated tap water. During a year s work,indicator bacteria and viral analysis were performed on each sample, we found that total plate count is 2×10~3—6.8×10~8/L, total coliforms is 130—5.5×10~4/L,fecal eoliforms is 10—960/L, coliphage is 0.35—65CFU/L, average is 26.48CFU/L, enteroviruses ...
