摘　　要：对事故氯气处理装置进行了工艺改进,当碱液氢氧化钠质量分数16%、氯气流量100kg/h、通氯时间8 h、反应终点ORP值为560 mV时,生产出的A型次氯酸钠产品有效氯质量分数在13%~14%、过碱量质量分数在0.65%-0.70%.氯酸盐质量分数在0.27%-0.28%,满足了用于自来水消毒的要求。The process of the unit for handling accidental release of chlorine was improved.When the mass fraction of sodium hydroxide in caustic solution was 16%,the chlorine flow rate was 100 kg/h,the chlorination time was 8 h,and the ORP value at the reaction end point was 560 mV,A-type sodium hypochlorite was produced.In the product,the mass fraction of effective chlorine was 13%-14%,sodium hydroxide 0.65%-0.70%,and chlorate 0.27%-0.28%.The product met the requirements for disinfection of tap water.
