Effect of Ammonia-Oxidizing Bacteria (AOB) on Chloraminated Disinfection Attenuation in Drinking Water Distribution System
城市供水管网生物膜中氨氧化细菌对氯胺消毒效果的影响

The growth of microbe and formation of biofilm in water distribution system were important factors affecting the security of water quality.The number of ammonia-oxidizing bacteria(AOB) in biofilm of a chloraminated drinking water distribution system in Shanghai was detected by MPN-Griess method,and the relations among AOB,nitrification and chloraminated disinfection were analyzed.Meanwhile,the effects of AOB on chloraminated disinfection fastness and attenuation by simulation experiment were studied.The res...
