摘要
综述了重金属废水的来源、危害及目前常用的处理技术。包括传统方法中的化学沉淀法、电化学法、吸附法和膜分离法;新出现的技术如纳米技术、光催化技术,以及新型介孔材料和基因工程。并对上述方法的机理、研究进展、优缺点进行了评述,同时阐述了处理重金属废水的技术和方法的发展趋势。
The source,harmfulness and treatment technologies currently used for dealing with heavy metal wastewater are summarized. For example,conventional methods include chemical precipitation,electrochemistry,adsorption and membrane methods,and new treating technologies include nanotechnology,photocatalytic technique,new mesoporous materials and gene engineering technique. The principles,research advance,merits and main problems of treatment techniques are reviewed. The trends and application foreground of heavy metal removal technology for wastewater are also elaborated in this paper.
