摘　　要：对比研究了2座自来水厂采用次氯酸钠消毒后的消毒效果和消毒副产物生成情况,并分析了次氯酸钠消毒系统的安全管理和运行成本。结果表明:改造前后的消毒效果无显著性差异,采用次氯酸钠消毒后出厂水余氯可稳定保持在原有水平,微生物安全性可以得到保障,各种消毒副产物均可稳定达标,吨水运行成本仅增加0.001元左右。改造既消除了液氯这一危险源,又确保了出厂水和管网水稳定达标。The disinfection effect and by-product formation of two waterworks after the application of sodium hypochlorite disinfection were compared and investigated,and the safety management and operation cost of sodium hypochlorite disinfection system were analyzed.The results showed that there was no significant difference in disinfection effect before and after modification.The residual chlorine in the treated water after disinfection with sodium hypochlorite could be maintained at the original level,the microbial safety could be guaranteed,all kinds of disinfection by-products could reach the standard steadily,and the running cost per ton of water increased by only 0.001 yuan.It not only eliminated the dangerous source of liquid chlorine,but also ensured the stability of treated water and pipeline network water.
