市政供水中耐氯菌的风险与控制研究

Research on the risk and control of chlorine resistant bacteria in municipal water supply

耐氯菌是当前饮用水安全保障研究中的一个热门话题,当饮用水中存在常规氯消毒无法灭活的有害细菌时,公众的健康和安全将会受到威胁.从常见的耐氯菌种类、耐氯菌的耐氯机理以及耐氯菌的风险控制三个方面探讨了市政供水中耐氯菌的风险问题.在分析了大量消毒、微生物和医学领域的研究后发现耐氯菌的风险虽然存在,但经过强化消毒处理以及末端控制后其风险是可控的.

Chlorine resistant bacteria is a hot topic of drinking water safety research.The public's health and safety are likely to be jeopardised if harmful bacteria cannot be inactivated by conventional chlorine disinfection.This study explores the risk of chlorine resistant bacteria in municipal water supply systems from three aspects:Types of chlorine resistant bacteria,chlorine resistant bacteria resistance mechanisms,and chlorine resistant bacteria risks control.After analyzing a large amount of research in the fields of disinfection,microbiology,and medicine,chlorine resistant bacteria are controllable after enhanced disinfection treatment and end control.
