摘要
含氯氧化剂在进行消毒或者污水处理应用时,会产生余氯残留的问题。寻求成本节约的高效余氯去除方法,具有重要的实际应用价值。本文对水中余氯去除的研究现状进行了综述,重点介绍了四价含硫化合物法、活性炭法、KDF介质过滤法、紫外光照法和其他几种余氯去除方法的应用,分析了这些技术用于水中余氯去除的机理,指出了各种方法存在的不足,并对后续的研究方向进行了展望。
Chlorine-containing oxidants cause chlorine residues when used in disinfection or wastewater treatment applications.It is of great practical value to seek a cost-effective and efficient method for removing residual chlorine.The research status of residual chlorine removal in water was reviewed,with emphasis on the application of tetravalent sulfur compounds,activated carbon,KDF medium filtration,UV irradiation and several other residual chlorine removal methods.The mechanisms of these technologies for removing residual chlorine in water were discussed,while the shortcomings were pointed out,and the future research directions were prospected.
