摘　　要：超临界水氧化技术(SCWO)是一种新型的有机废水处理技术,具有反应速率快、处理效果好、不形成二次污染和去除效率高等优点。文章介绍了超临界水的特性和国内对难降解有机污水的超临界氧化处理试验成效,反应系统材料腐蚀研究,催化剂开发研究,并指出了国内技术开发面临的突出问题。Supercritical water oxidation （SCWO） is a new technology for treatment of organic wastewater with characteristics of fast reaction rate, no new pollution and high removal efficiency. Characteristics of superficial water as well as results of SCWO treatment of refractory to degradation organic wastewater with high concentration were introduced, and material corrosion of reactor and development of catalyst were reviewed. Problems during R ＆ D of SCWO were also proposed.
