中文摘要：

印染废水因具有高色度、高有机物浓度、难生物降解的独特性质,一直是国内外环境领域关注的重要水体污染源之一。零价铁由于其独特的性质,已成为国内外研究处理印染废水的主要方向之一。介绍了零价铁的研究现状,分析了零价铁降解印染废水的作用机理、动力学及影响因素,着重介绍了近几年新兴的几种零价铁与其他水处理技术联用的复合工艺对印染废水的降解作用。最后,对现存的一些技术问题进行了讨论。

英文摘要：

Printing dyeing wastewater,as one of the main sources of water pollution in China and abroad,has always been a hot research topic in the field of environmental treatment,because of its specific characteristics of highchroma,high concentration of organic matter,and refractory bio-degradation. Zero-valent iron has become one of the principal directions of the research on printing dyeing wastewater treatment in the world for its unique characteristics. The present research on the application of zero-valent iron is introduced. Its degradation mechanism,as well as kinetics,and influencing factors of zero-valent iron,used for the degradation of printing dyeing wastewater are analyzed. The effect of several kinds of newly-developed composite processes of zero-valent iron combined with other water treatment techniques on printing dyeing wastewater degradation are introduced emphatically. At the end,some technical problems existing at present are discussed.
