This study profiled the bacterial community variations of water from four water treatment systems,including coagulation,sedimentation,sand filtration,ozonation-biological activated carbon filtration(O3-BAC),disinfection,and the tap water after the distribution process in eastern *** results showed that different water treatment processes affected the bacterial community structure in different *** traditional treatment processes,including coagulation,sedimentation and sand filtration,reduced the total bacterial count,while they had little effect on the bacterial community structure in the treated water(before disinfection).Compared to the traditional treatment process,O3-BAC reduced the relative abundance of Sphingomonas in the finished *** addition,ozonation may play a role in reducing the relative abundance of *** and ClO2 had different effects on the bacterial community in the finished *** relative abundance of some bacteria(***,Phreatobacter and Porphyrobacter)increased in the finished water after ClO2 *** relative abundance of Mycobacterium and Legionella,which have been widely reported as waterborne opportunistic pathogens,increased after NaClO *** addition,some microorganisms proliferated and grew in the distribution system,which could lead to turbidity increases in the tap *** to those in the finished water,the relative abundance of Sphingomonas,Hyphomicrobium,Phreatobacter,Rheinheimera,Pseudomonas and Acinetobacter increased in the tap water disinfected with NaClO,while the relative abundance of Mycobacterium increased in the tap water disinfected with ***,this study provided the detailed variation in the bacterial community in the drinking water system.
