针对我国７大水系及湖泊水质日趋恶化有机污染日益严重，氯消毒产生卤代甲烷等强致癌物质而危害人体健康的现实，提出用ＣｌＯ２替代一般氯制剂对饮用水消毒．运用大量数据和实例，论证了用ＣｌＯ２替代一般氯制剂的必要性和可行性．并对使用ＣｌＯ２消毒的安全性进行了论述 In response to the increasing deterioration of the water quality of seven major river systems and lakes in China, organic pollution is becoming increasingly serious. Chlorine disinfection produces strong carcinogens such as halogenated methane and poses a threat to human health. It is proposed that ClO2 be used as a substitute for general chlorine preparations to sterilize drinking water. Using a large amount of data and examples, the necessity and feasibility of using ClO2 as a substitute for general chlorine agents were demonstrated. And discussed the safety of disinfection using ClO2
