摘　　要：开发了一种短时游离氯消毒后加氨转化为氯胺的顺序氯化消毒工艺,该工艺可充分利用游离氯灭活微生物迅速彻底、氯胺生成消毒副产物少的优势,安全经济地实现对微生物指标的双重控制。在天津市某水厂的中试表明,该消毒工艺对细菌总数、总大肠菌群的控制效果略好于单纯游离氯消毒,说明游离氯和氯胺可能因为攻击位点不同而存在一定程度的协同效应。The short-term free chlorine plus chloramine can make full advantages of free chlorine＇ s quick inactivation of microorganism and chloramine＇ s low formation of disinfection products （DBPs）, so as to achieve the control of both microbe and DBPs. Pilot-scale test was carried out in a Tianjin water treatment plant, the result shows that this disinfection process is little more effective than free chlorine process in the control of total count of bacteria and total coliforms. It also shows that free chlorine plus chloramine may have some synergistic effect due to the different attacking point.
