摘　　要：随着经济的快速发展和人民生活水平的不断提高,铬在工业领域的应用极其广泛,其排出的含铬废水必对环境造成了严重的污染。铬通常以三价或六价形态存在于环境中,其化合物的价态决定了它的毒性。含铬废水的污染源及污染防治技术较复杂,因此,研究含铬废水的处理是一个热点问题。结合国内外的研究成果,本文主要综述了内电解法、活性污泥法、钡盐法、光催化法以及木质纤维素废弃物吸附法等方法和工艺对含铬废水的处理研究,并为其处理技术的选择提供了依据,以及未来的前景发展进行了展望。With the rapid development of economy and the continuous improvement of people＇s living standard,chromium is widely applied in the field of industry,and the discharge of chromium- containing wastewater will cause serious pollution to the environment. Chromium is usually present in the environment of trivalent or six valence,and the valence state of its compound determines its toxicity. The pollution source and pollution prevention technology of chromium- containing waste water is complex,therefore,the research of chromium- containing wastewater treatment is a hot issue. Combined with the research results at home and abroad,the purpose of this article is to review the internal electrolysis,active sludge method,barium salt method,photocatalysis method,and adsorption method of lignocellulosic wastes and processes research on treatment of chromium- containing wastewater,and offers references to the choice of its processing technology,as well as the prospect of future development was prospected.
