摘　　要：超临界水氧化(SCWO)在过去的30年中作为取代焚烧处理高浓度工业有机废水的技术开发取得了巨大的进展。SCWO作为新型废物处理技术存在一些缺陷,如反应器腐蚀与盐堵塞阻碍了其工业进程中的应用。详细描述了超临界水氧化技术存在的几类相关问题,其中,重点对该技术工业化的应用难点进行了阐释并提出了相应的解决方案,最后对超临界水氧化技术领域的未来研究方向提出了展望与建议。In the past thirty years,supercritical water oxidation( SCWO) has made great progress as a substitute for incineration in the treatment of highly concentrated industrial organic wastewater.As a new treatment technology,SCWO has however some defects such as corrosion and salt plugging problems to reactors,which hinder its application in the industrial waste treatment process. The existing problems of SCWO are described in details and the key points for industrial application of SCWO are explained and unscrambled. The future research direction of SCWO is proposed. In addition,the thermal energy utilization of SCWO is also described and the results show that SCWO has some great advantages than normal waste treatment technology.
