摘　　要：为避免液氯消毒中潜在的安全隐患,江东水厂将其消毒工艺改造成次氯酸钠消毒,并对消毒效果进行了研究。结果发现,江东水厂采用次氯酸钠消毒后,出厂水余氯的稳定性更好,消毒副产物含量更低,并有一定的助凝效果。次氯酸钠投加系统构成简单、操作方便,但成本略高于液氯。To control safety risks, Jiangdong Water Plant changed the disiniectlon process trom liquid chlorine to sodium hypochlorite, and researched the subsequent effects. The results showed that when disinfected by sodium hypochlorite, the residual chlorine was more stable, and less disinfection by- products were found in the effluent. Sodium hypochlorite also promoted the coagulation effect. The sodi- um hypochlorite disinfection system was simple and easy to operate, but the cost was slightly higher than that of the liquid chlorine disinfection system.
