摘要
超临界水具有通常状态下的水所没有的特异性质 ,它可以与氧以任意的比例相混合而成于一相 ,从而提供了超临界水氧化反应的溶剂环境。将超临界水氧化技术应用于环境保护是一个新的研究方向 ,由于该技术对废物处理具有经济、快速、高效等特点 ,近几年来发展非常迅速。笔者介绍了超临界水的性质和超临界水氧化技术的原理与优点 ,综述了超临界水氧化技术处理有毒有机废物、下水污泥及人体代谢污物等方面的应用 ,并指出了超临界水氧化技术研究中存在的问题 ,最后介绍了超临界水氧化技术在工业上的应用现状。
The supercritical water has some special characteristics that common water has no, and it can mix with oxygen with any ratio and offer solvent condition of SCWO reaction. It is a new research aspect to apply the SCWO technology on environmental protection. The technology has rapid development in recent years because of its many advantages such as low cost, good speed and high efficiency in disposing of wastes. The paper introduces the characteristics of supercritical water and the principles of SCWO, and reviews the applications of SCWO technique in treating poison organic wastes, downflow sludge and human metabolism, and point out the problems of SCWO during the research, and finally the application progresses in industry are introduced.
