| 摘 要： | 在氯消毒研究的基础上,研究氯胺对消毒副产物的控制,将氯与氨氮的比值降至5,能够使单独氯消毒所生成消毒副产物减少89%,二溴一氯甲烷也不再检出;消毒副产物的生成量与氯胺的投加量呈很好的线性关系;接触时间对消毒副产物的生成量影响很小,24 h增加缓慢;pH升高至8消毒副产物的总量比pH为7时减少82.3%,一溴二氯甲烷不再检出;氯胺代替氯消毒能够很好地控制溴代消毒副产物种类和总量.

| Abstract: | Using monochlosamine to study how to control disinfection by-products based on the research of chlorine disinfection.Decreasing the ratio of chlorine to ammonia to 5 can reduce DBPs by 89 percent and no dibromochloromethane was detected;the amount of DBPs had a good pertinence to the monochloramine dose;contact time had little effect on DBPs,and DBPs had little slow increase after 24 hours;increasing pH value to 8 can decrease DBPs by 82.3 percent and there was no bromodichloromethane was detected and using monochloramine in place of chlorine help control bromo-DBPs variety and quantity. |
