Revien on techniques of catalytic wet air oxidation

催化湿式氧化技术是在高温高压条件下处理高浓度、有毒有害且难生物降解污染物的一种高级氧化技术。本文在检索了国内外大量参考文献的基础上,概述了催化湿式氧化技术的最新进展、机理及动力学,总结了催化湿式氧化技术中催化剂的分类、组成、特点及其在废水处理中的应用,以期对有关研究者提供一定的借鉴作用。本文最后肯定并展望了催化湿式氧化技术是有广阔应用前景的水处理技术。

With the development of modern industry, the species and quantity of wastewater rapidly increase. However, some of them can't be treated by common methods. Gradually, Catalytic Wet Air Oxidation (CWAO) technology came into being. CWAO is an advanced oxidation technology for hazardous, toxic, nocuous and non - biodegradable contamination in the wastewater at high temperature and pressure. At first, the wtiter seached large numbers of references at home and abroad. Based on this, the article summarized this technology's developments, mechanisms and kinetics. Of Catalytic Wet Air Oxidation, the catalysts contain metal salt series, metal/ carrier series, oxide/carrier series, compound-oxide/carrier series. Every kind of catalyst takes on respective different characteristics. What's more, CWAO technology also possesses economic feasibility. Certain use for reference to some rearchers can be expected. We can affirm that CWAO technology is a kind of prospective wastewater treatment technology.
