摘要
杀菌消毒是水处理中至关重要的一个环节,传统的含氯氧化剂在消毒的同时会产生严重危害人体健康的消毒副产物,抗菌性纳米材料以其独有的特性不仅具有良好的杀菌消毒效果,而且不产生对人体有害的副产物。从纳米材料的抗菌原理、基本方法、常用材料种类等几方面对近5年来抗菌性纳米材料在水处理中的应用现状进行了讨论,分析了其目前存在的问题和发展前景,并在此基础上提出了一些新的看法。
Sterilization and disinfection is a significant step in water treatment. In traditional way, oxidants which contain chlorine are widely used as disinfector but with disinfection by-products which do harm to people＇ s health. Antibacterial nanoscale materials have good sterilization effect without harmful by-product due to the particular characteristics. In this paper the development of antibacterial nanoscale materials in water treatment in recently five years is reviewed from the aspects of principle, kinds of material and ways. The advantages and shortcomings are discussed and some original thoughts or suggestions are also put forward about the applications of antibacterial nanoscale materials in water treatment.
