摘　　要：铬作为重要的战略金属元素,在工业领域应用极广,因此涉铬行业众多,造成了严重的环境污染。在环境中铬主要以三价铬和六价铬形态存在,其中六价铬毒性大,致癌致畸变作用强,其污染源和污染防治技术复杂,是国家重点控制的五大重金属污染物之一。文章介绍了六价铬污染的特性、污染现状和含六价铬废水不同处理技术的工艺特点及应用情况,概述了国内外六价铬废水处理技术的研究进展,为六价铬废水处理技术的选择提供了依据。Chromium, as important strategic metal elements, is widely used in industry fields. There are great quantities of industry sectors involving chromium, causing serious environmental pollution. The most common existing forms of Cr are Cr(Ⅲ)and Cr(Ⅵ). Cr(Ⅵ), which has been identified as one of the top five focus control heavy metal pollutants, is highly toxic, carcinogenic and mutagenic. This paper introduced the characters of chromium pollution, the contamination status and the process features and applications of different treatment technologies. It also reviewed the research progress of chromium wastewater treatment technology both at home and abroad, looked forward to provide the basis for the choices of treatment technologies.
