高浓度难降解有机废水的催化氧化技术发展

在催化氧化法的研究发展中，产生的湿式催化氧化法，光催化氧化法，均相催化氧化法和多相催化氧化法４个分支，在实质上，它们都对氧化剂的分解产生催化作用，以加快放心水中与氧化剂之间的化学反应。由于某些强氧化可要催化作用下产生更强氧化性的基团，能够使一些高浓度难解的有机物氧化分解，因此催化氧化法成为处理高深度难降解有机废水一项重要的新技术。本文将对催化氧化法的研究发展，应用情况分类予以介绍。

Development of Catalytic Oxidation Technology for the Treatment of Highly Concentrated and Refractory Organic Wastewater

Four branches of the catalytic oxidation process have been formed, i. e., wet catalytic oxidation;photocatalytic oxidation; homogeneous catalytic oxidation and heterogeneous catulytic oxidation.substantially, they all catalyze the decomposition of oxidant so as to speed up the chemical reactions between organic matters and oxidant in wastewater.Some powerful oxidants can produce much stronger radicals by catalysis to oxidate and decompose some highly concentrated and refractory organic matters.Therefore, catalytic oxidation becomes important as a new technology for the treatment of highly concentrated and refractory organic wastewater.
