超临界水氧化法进行废水处理的研究进展

Progress on Waste Water Treatment of SupercritiCal Water Oxidation

超临界水氧化法是一种新兴且非常有效的废水处理方法。当水处于临界点以上时 ,溶解在超临界水中的O2 或H2 O2 可以将超临界水中的有机物氧化生成H2 O和CO2 等物质。本文介绍了超临界水的特点、SCWO的流程及其特点和反应机理 ,论述了该法存在的问题和解决的方法。

Supercritical water oxidation(SCWO) is a recently developed technology for waste water treatment by which the organic compounds are oxidized by an oxidant in the presence of water above its critical point.SCWO is an environmentally benign process which produces a disposable clean product H 2O,CO 2 and etc.This rewiew introduces the characteristics of supercritical water(SCW),the process and reaction mechanism.Finally the existing problems and solving methods related to SCWO are discussed.
