摘　　要：湿式催化氧化法是一种有效处理高浓度、高毒性以及难生物降解有机废水的方法。作者对湿式催化氧化法进行了总体概述,重点介绍了湿式催化氧化法的分类,不同种类催化剂的优缺点及国内外研究进展和该方法在废水处理中的应用。对该技术的研究方向进行了展望,指出该领域催化剂的研究方向,为在铜系催化剂的研制基础上结合稀土类元素,在保证非均相催化剂高活性的前提下,减少活性组分的溶出,以提高催化剂的稳定性。Catalytic wet oxidation （CWO） is an efficient method for treating organic wastewater that is highly con- centrated, toxic, and difficult to be biodegraded. The technology of catalytic wet oxidation is summarized. Emphases is placed on the introduction of the categories of catalytic wet oxidation, advantages and disadvantages of different catalysts and their research progress in China and abroad, as well as its application to wastewater treatment. It is prospected that the copper-based catalysts combining with rare-earth-type elements are the research direction of the catalysts in the CWO technology. On the basis of keeping high activity of heterogeneous catalyst, it is necessary to reduce the dissolution of active components in order to enhance the stability of the catalyst.
