超临界水氧化技术及应用发展

Supercritical water oxidation technology and its application development

超临界水能与氧或空气完全互溶,能快速氧化有机废物成为无害的液体或气体等无机小分子化合物。因此超临界水氧化(SCWO)技术近几年来发展迅速,成为一种极具潜力的绿色有机废水处理技术。作者介绍了超临界水氧化技术的特点、原理、工艺流程和装置,当前国内外研究和工业应用现状及应用中存在的问题和研究方向。

The supercritical water and oxygen or air can completely be dissolved with each other, and can oxidize organic waste rapidly, becoming harmless liquid or gaseous inorganic small-molecular compound. Therefore, the supercritical water oxidation （SCWO） technology has rapid development in recent years, and has become a potential and green organic wastewater treatment technology. Its features, principles, process flow and reactor are introduced. Its application is presented in detail. The problems in its application and future research orientation are pointed out.
