摘　　要：微生物安全是饮用水处理面临的主要问题之一,在发生水源微生物污染时确保供水的水质安全意义重大。文中结合国内外饮用水水质标准的指标要求,探讨了水厂几种常用工艺对病原微生物的去除效果及消毒副产物控制效果,在此基础上提出3种典型工艺流程的水厂在应对水源病原微生物污染时的应急水处理措施,重点分析水源存在有机物、氨氮等物质影响下的处理措施,以期为几种典型工艺流程水厂应对水源病原微生物污染提供参考。Microbiological safety is one of the major issues of drinking water treatment,it is of great significance to ensure the microbial safety of drinking water in water pollution accidents.In this paper,the microbiology requirement in drinking-water quality standard at home and abroad are introduced,and the technologies of removing the pathogenic microorganisms and controlling the disinfection by-products are discussed.The water treatment measures of ensuring the drinking-water safety are pointed out with a focus on three typical processes.The influences of organic matter and ammonia nitrogen are analyzed,and the solution are put forward.It provides suggestions of controlling pathogenic microorganisms for WTPs with several typical processes.
