Abstract

Coliphages were monitored in conjunction with indicator bacteria and enteroviruses in a drinking-water plant modified to reduce trihalomethane production. Coliphages could be detected in the source water by direct inoculation, and sufficient coliphages were detected in enterovirus concentrates to permit following the coliphage levels through different water treatment processes. The recovery efficiency by different filter types ranged from 1 to 53%. Statistical analysis of the data indicated that enterovirus isolates were better correlated with coliphages than with total coliforms, fecal coliforms, fecal streptococci, or standard plate count organisms. Coliphages were not detected in finished water.

摘要

在一个为减少三卤甲烷生成而改造的饮用水处理厂中,对大肠杆菌噬菌体与指示菌及肠道病毒进行了联合监测。通过直接接种可在原水中检测到大肠杆菌噬菌体,并且在肠道病毒浓缩物中检测到了足够数量的大肠杆菌噬菌体,以便追踪不同水处理过程中的噬菌体水平。不同类型过滤器的回收效率在1%至53%之间。数据的统计分析表明,肠道病毒分离株与大肠杆菌噬菌体的相关性比与总大肠菌群、粪大肠菌群、粪链球菌或标准平板计数微生物的相关性更好。在成品水中未检测到大肠杆菌噬菌体。
