摘　　要：研究了短时游离氯后转氯胺的顺序消毒工艺．结果表明，该消毒工艺对指示微生物的灭活效果优于游离氯消毒。游离氯和氯胺存在协同消毒作用；对脊髓灰质炎病毒和大肠杆菌f2噬菌体的灭活效果与游离氯相同．相同原水条件下，顺序氯化消毒工艺产生的三卤甲烷浓度比游离氯消毒工艺减少35．8％～77．0％；卤乙酸减少36．6％～54．8％．消毒进水水质越差，顺序氯化消毒工艺在消毒副产物（DBP）控制方面就越具优势．The sequential disinfection technology of short-time free chlorine transformed to chloramine was studied. The inactivation efficiency of this technology on monitor microorganism was better than the free chlorine disinfection, Free chlorine and chloramines had coordinative disincentive action. The efficiency of poliovirus and coliphage f2 was same to the free chlorine. Under the condition of same original water, the THMs and HAAs produced from sequential chlorination disinfection technology was 35.8%～77.0% and 36.6%～54.8% less than those from free chlorination. The more worse water quality of inflow disincentive water, the more prior the sequential chlorination disinfection technology in the respect of disinfection by-product control.
