Phenolic wastewater treatment by catalytic wet air oxidation with fixed bed containing carbon

采取湿法催化过氧化物氧化法,提出独特的碳载固定床装置。通过一定的预处理将钴固载在活性炭上制成炭载钴,研究该水处理剂的湿式催化和吸附富集作用。利用活性炭吸附污水中的有机物对苯二酚和钴的催化氧化作用降低对苯二酚的分解活化能,结合Fenton反应机理探论了C02+非均相催化反应机理,开发出一种很有开发前景的有机废水处理技术,实验结果满意。

Using peroxide oxidation catalyst of wet air oxidation, the fixed bed on active carbon installation is put forward. Through a certain pretreatment, the eobah- activated carbon is made from carbon containing cobalt to study the treatment of the wet adsorption and catalytic role enrichment. Using activated earbon to adsorb organic matter in sewage hydroquinone and cobalt catalytic oxidation af hydro- quinone to lower aetivation energy of the decomposition, combined with Fenton reaction mechanism with the exploration of CO2 ＋ heterogeneous catalytic reaetion mechanism, we developed a very promising development of organie wastewater treatment technology, and the experiment results are satisfactory.
