中文摘要	在中试规模试验中,研究了“短时游离氯后转氯胺的顺序氯化消毒工艺”对微生物、消毒副产物和生物稳定性指标的控制效果.该顺序氯化消毒工艺综合利用了游离氯消毒灭活微生物迅速彻底,氯胺消毒副产物生产量低的特点,通过氯化消毒技术的组合,安全经济地实现了消毒卫生学和消毒副产物指标的双重控制.该消毒工艺对细菌总数、异养菌平板计数、总大肠菌群指标的控制效果略好于传统游离氯消毒,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,顺序氯化消毒工艺比游离氯消毒工艺产生的三卤甲烷浓度减少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控制方面就越有优势.该工艺对生物稳定性指标的控制效果明显高于游离氯消毒.; A new safe chlorination disinfection process,the sequential disinfection process with short-term free chlorine plus chloramines was investigated its efficiency on control of indices of microorganism,disinfection by-products and bio-stability.This disinfection process may take the advantage of free chlorine's quick inactivation of microorganism and chloramines' low DBP yield and long term residual.Thus,both control of microorganisms and DBPs can be achieved effectively and economically.The pilot test results show that safe chlorination disinfection process has a little better efficiency on total bacteria count,HPC and total coliform count than free chlorination disinfection,which indicate that free chlorine and chloramines might have the synergetic disinfection effect for their different attacking targets.It also had the same inactivation efficiency on polio virus and coliphage f_2 as free chlorination in 120 minutes contact time.Sequential chlorination disinfection process could reduce 35.8%～77.0% yield of trihalomethane and 36.6%～54.8% yield of haloacetic acids.The poorer quality the water had,the more advantage the safe-chlorination disinfection had than free chlorination disinfection one.Moreover,sequential chlorination had better efficiency on bio-stability control than free chlorination.; 国家高技术研究发展计划(863)项目(2002AA601140); 国家自然科学基金重点项目(50238020)
