催化氧化法处理焦化废水研究

         

摘要

As high concentration organic wastewater, coking wastewater is poisonous, harmful and difficult biodegradable. Catalytic oxidation process can decompose organic macromolecular material and reduce coking wastewater toxicity. In this article, research status of catalytic oxidation treatment of coking wastewater was mainly introduced, including electrode catalytic method, electrochemical catalysis method, wet catalytic oxidation, supercritical water oxidation method, catalytic coupling method, titanium dioxide photo catalysis method and ultrasonic collaborative light catalysis, and so on. Various methods were summarized and evaluated. Then, some suggestions of research direction in the future were put forward.%  焦化废水是一种有毒有害、难生物降解的高浓度有机废水,催化氧化法能够分解有机大分子物质、降低焦化废水毒性,近年来国内外学者对其研究较多。介绍了催化氧化法处理焦化废水的研究现状,包括电极催化法、电解催化法、湿式催化氧化法,超临界水氧化法、催化耦合法、二氧化钛光催化法和超声协同光催化等。对各种方法进行了综述和评价,同时对催化氧化法处理焦化废水今后的研究方向提出了建议。
