次氯酸钠替代液氯消毒在水厂的应用与优化

Application and Optimization of Disinfection Process with Sodium Hypochlorite in Place of Liquid Chlorine in WTP

使用次氯酸钠代替液氯消毒可以从源头上消除使用液氯带来的安全隐患,在保障供水水质生物安全的前提下,对比汕头市月浦水厂使用液氯与次氯酸钠消毒的实际效果,研究次氯酸钠溶液有效氯成分的稳定性。经试验对比研究,论证实际制水生产中使用低浓度次氯酸钠溶液的可行性与必要性。

Potential safety problems of chlorination can be reduced by application of disinfectant sodium hypochlorite in place of liquid chlorine.Under the premise of ensuring biological safety of water supply,effect of liguid chlorine and hypochlorite on disinfection in Yuepu water treatment plant(WTP)was compared.The stability of sodium hypochlorite solution and the optimization of its use in actual production was studied,in order to standardize waterworks using sodium hypochlorite disinfectant.Laboratory study proved that it's feasible and necessary to use low concentration of sodium hypochlorite solution in WTP.
