摘　　要：通过模拟水厂消毒工艺,比较了氯气与氯胺两种消毒方式的消毒效果及消毒副产物三卤甲烷(THMs)生产量。结果表明,氯胺消毒能有效灭活水中的细菌和致病微生物,氯胺消毒较氯气产生THMs等致癌致突变的化合物明显降低;氯胺的稳定性好,在管网水中持续时间长,可以有效控制管网中的有害微生物的繁殖和生物膜的形成,杀菌持久性强,可以更好地满足管网余氯量的要求。According to the simulation of disinfection process in waterworks, the disinfection effect and generation of disinfection by-products trihalomethanes （THMs） were compared between chlorine and chloramine disinfection. The results indicated that chloramine disinfection could inactivate bacteria and pathogenic microorganism in water effectively. Compared with chlorine disinfection, the generation of THMs was decreased obviously by chloramine disinfection. Chloramine had satisfied stability, the duration time was long in pipelines, and could control the propagation of harmful microorganism and the formation of biofilm in pipeline effectively. Sterilization persistence of chloramine was good which could ensure the residual chlorine in pipeline.
