Viruses and coliform bacteria were detected in untreated hospital sewage water. The amount of viruses reaches 6-78PFU/L. Viruses were detected from treated hospital sewage water samples which mets acceptable limits for total coliform bacteria and residual chlorine. The amount of viruses is 5.12-51PFU/L in the treated sewage water. The efficiency of virus removal is 34.07%. The sewage water from treated hospital sewage water which meets water Quality Quidelines can not be assumed to be virus free. 医院污水 次氯酸钠 肠道病毒 大肠菌群 hospital sewage water enteric virus coliform bacteria sodium hypochlorite 1989-01-01 2021-04-01 1
