摘要

氯消毒通常用于灭活饮用水处理厂中的致病病毒。然而，水质在氯消毒病毒中的作用尚未得到深入研究。在这项研究中，我们使用从日本四家大型饮用水处理厂收集的实际水样，在12个月的时间里，在严格的浊度管理下（低于0.14NTU），研究了游离氯对柯萨奇病毒B5（CVB5）的灭活效率。结果表明，CVB5的氯消毒可能不受水质的影响。日本的浊度管理可能在控制氯消毒效率方面发挥间接作用。

Inactivation of coxsackievirus B5 by free chlorine under conditions relevant to drinking water treatment.

Chlorine disinfection is commonly applied to inactivate pathogenic viruses in drinking water treatment plants. However, the role of water quality in chlorine disinfection of viruses has not been investigated thoughtfully. In this study, we investigated the inactivation efficiency of coxsackievirus B5 (CVB5) by free chlorine using actual water samples collected from four full-scale drinking water treatment plants in Japan under strict turbidity management (less than 0.14 NTU) over a 12-month period. It was found that chlorine disinfection of CVB5 might not be affected by water quality. Japanese turbidity management might play an indirect role in controlling the efficiency of chlorine disinfection.
