摘要
随着水资源的日益紧缺和人们环境保护意识的提高,传统的水处理技术已经逐渐不能满足社会发展的需求。近年来,纳米技术和纳米材料的迅速发展为水处理技术的革新提供了良机,引起了众多环境科研工作者的广泛研究。文章综述了近年来纳米材料在污染物吸附、膜分离、光催化氧化等水处理领域的应用研究进展,系统阐述了各种纳米技术的优势、作用机理、影响因素、对水的处理效果、技术成熟程度等,并对纳米材料在水处理领域的发展进行了展望。
With the severe shortage of water and the fast growing demand of environment protection, traditional water treatment technologies cannot meet the demand of the development of society. Recent advances in nanotechnology offer leapfog-ging opportunities to develop next-generation water treatment, which attract the attention of many researchers. Here an overview of nanomaterials used in adsorption, membrane processes and(photo)catalysis is presented, the discussion covers the advantages compared to existing process, mechanism, influencing effect, etc. By tracing the advances of nanomaterials, their prospects in water treatment are outlined.
