摘　　要：催化超临界水氧化技术是在超临界水氧化技术基础上,借鉴催化湿式氧化技术发展起来的一种高效环保的有机废弃物处理技术,可以提高有机污染物的氧化速率,降低工艺条件,拥有十分广阔的应用前景。综述了近年来催化超临界水氧化技术在处理工业污水中催化剂、反应机理、反应动力学、反应器的研究进展。提出了催化超临界水氧化技术的研究方向,以期为催化超临界水氧化技术处理难降解有机污水的发展提供参考。Catalytic supercritical water oxidation technology is an efficient and environmentally friendly organic waste treatment technology. The technology is developed on the basis of supercritical water oxidation technology and borrowed from catalytic wet oxidation technology. Adding the catalyst in the process can reduce the process conditions and thus increase the oxidation rate of organic pollutants. The technology has a broad application prospect.This paper reviewed the research progress of catalysts,reaction mechanisms,reaction kinetics and reactors in the treatment of industrial wastewater by catalytic supercritical water oxidation technology. The advantages of heterogeneous catalysts were analyzed,and the research direction of catalytic supercritical water oxidation technology was proposed. This study is expected to provide a reference for the development of catalytic supercritical water oxidation technology to treat refractory organic wastewater.
