摘要
超临界水(SCW)具有与常态下的水截然不同的性质,由此导致了超临界水的多种用处。超临界水氧化(SCWO)作为一种以超临界水为介质的新的废物处理技术以其完全快速等优点而日渐成为研究的热点。本文介绍了超临界水的特性和超临界水氧化的基本原理,反应器的装置,综述了超临界水氧化的动力学、应用、工艺改进、工程问题等方面的研究进展情况。
The critical point of water is 374℃,22.1MPa.In a supercritical environment,water has many different properties from that of normal condition,which results to its multiple uses.Supercritical water oxidation is a new waste treatment technology.It has the characteristics of complete and quick oxidation of toxic material.This paper discussed the special properties of SCW,the basis of the SCWO process and reactor.It also reviewed the progress of research and application in this field.
