近年来,城市自来水安全越来越受到人们的重视,随着新型自来水处理工艺——臭氧-生物活性炭工艺(O3/BAC)的应用普及,自来水的安全性在得到提高的同时,还发现该工艺存在自来水生物安全隐患。文章在总结分析国内外学者相关研究和借鉴国内外关于水污染风险评价理论的基础上,建立了自来水处理工艺中生物安全的时序风险评估体系。从事前、事中和事后三个阶段评估自来水生物安全风险,并提出了相应的应急管理对策,以控制和减少自来水中无脊椎动物生物的数量,从而提高居民生活用水质量,防控自来水水质突发事件的发生。
In recent years, more and more attention has been paid to the safety of tap water in urban areas. With the popularization of the new tap water treatment technology, O3 / BAC, the safety of tap water has been improved. At the same time, There are tap water biological safety problems. Based on the analysis of the domestic and foreign scholars related research and drawing lessons from domestic and foreign water pollution risk assessment theory, this paper established a time risk assessment system of biosafety in tap water treatment process. Evaluate the risk of tap water biological security in the three stages before, during and after the event, and put forward the corresponding emergency management countermeasures to control and reduce the number of invertebrate organisms in tap water, so as to improve the quality of domestic water and prevent the quality of tap water The incident occurred.
