水厂饮用水肠道病毒工艺控制与污染防范

Process control of enterovirus and prevention of virus contamination in drinking water in waterworks

介绍了饮用水中肠道病毒的控制标准和指示物、工艺控制和防控措施。饮用水中的病毒以大肠杆菌噬菌体作为指示物,以EPA的病毒去除率为标准。从工艺方面可以采取控制滤后水浊度、提高消毒CT值、强化工艺组合等措施,同时水厂可从水源地、工艺废水和污泥、生产环境、接触人员等方面开展病毒污染防控。

The control standards and indicators of enterovirus in drinking water,process control and control measures were introduced. E. coli was used as the indicator of virus in drinking water,and the EPA virus removal rate as standard. For process operation,measures such as controlling the turbidity of filtered water,improving the disinfection CT value,and strengthening the process combination could be taken,and at the same time,the waterworks could carry out virus contamination prevention and control from the aspects of water source,process wastewater and sludge,production environment and contact personnel,etc.
