摘　　要：以南方某净水厂臭氧活性炭工艺段出水为研究对象,考察次氯酸钠对微生物的灭活效果以及消毒副产物的生成规律。结果表明,当次氯酸钠投加量为12～20 mg/L,反应60 min时,可使菌落总数降至低于20 CFU/mL,此时总大肠菌群未检出,反应后余氯达到0.51 mg/L以上,消毒副产物总量不超过1,可确保饮用水质安全。Based on the effluent of ozone/activated carbon process in a drinking water plant in South China, the killing effect of sodium hypochlorite and the formation rule of disinfection by-products were investigated. The results showed that when 12~20 mg/L sodium hypochlorite was added with 60 min reaction time, the total numbers of bacterial colony could drop to 20 CFU/mL, the total coliform was not detected, the residual chlorine reached more than 0.51 mg/L, and the total disinfection by-products were more than 1, ensuring the safety of drinking water quality.
