“消毒”路漫漫一百多年前,自来水行业开始采用氯气消毒,氯气消毒有着价格低、操作使用简单、消毒持续性好等优点,一度成为使用最广泛的消毒方式。但是氯气本身有剧毒,而且液氯在运输、存储和操作过程中存在安全隐患,随后二氧化氯以其强氧化能力在欧美被采用。然而二氧化氯不稳定,难以保障安全运输,在二氧化氯制备的过程中,大量未参与反应的有毒原料(氯酸盐等)对水质也会造成了二次污染。此外,二氧化氯的运行成本很高, “Disinfection ” Road Long 100 years ago, the water industry began to use chlorine disinfection, chlorine disinfection has the advantages of low price, simple operation, good disinfection and so on, was once the most widely used disinfection. However, chlorine itself is highly toxic, and there is a safety hazard in the transport, storage and handling of liquid chlorine. Chlorine dioxide is subsequently used in Europe and the United States for its strong oxidizing power. However, chlorine dioxide is unstable and it is difficult to ensure safe transportation. In the process of preparing chlorine dioxide, a large amount of toxic raw materials (chlorate and the like) that are not involved in the reaction can also cause secondary pollution to water quality. In addition, the cost of running chlorine dioxide is high,
