摘　　要：文章以某水处理厂饮用水升级改造项目为例,通过对比NaClO消毒剂替代液氯消毒剂前后水质指标变化和余氯变化情况,结果表明,以NaClO消毒剂替代液氯消毒剂,对饮用水出水水质影响不显著,NaClO消毒剂投加量为20 mg/L时,即可满足饮用水出厂咋余氯控制在0.70~0.90 mg/L控制要求。当长距离出水管线余氯指标偏低时,可通过补氯工艺提高管网余氯含量。NaClO消毒剂成本高于液氯,但安全性较高。Taking the drinking water upgrading project of a water treatment plant as an example,by comparing the changes of water quality indexes and residual chlorine before and after replacing liquid chlorine disinfectant with NaClO disinfectant,the results show that replacing liquid chlorine disinfectant with NaClO disinfectant has no significant impact on the quality of drinking water outlet.When the dosage of NaClO disinfectant is 20 mg/L,It can meet the control requirements of residual chlorine in drinking water at 0.70~0.90 mg/L.When the residual chlorine index of long-distance water outlet pipeline is low,the residual chlorine content of pipe network can be improved by chlorine supplement process.The cost of NaClO disinfectant is higher than that of liquid chlorine,but its safety is higher.
