摘要

为响应政府“工业废水零排放”政策，煤化工水处理领域通常采用臭氧催化氧化技术对含盐废水进行深度处理，使出水COD满足后端工艺单元，如膜处理单元、蒸发结晶单元的进水要求，从而保证装置的整体稳定运行。着重介绍了臭氧催化氧化降解有机物的反应机理、该技术的分类及不同技术的反应方式、当前研究水平下制备催化剂的常用材料，并阐述了不同材料作催化剂时的优劣，总结了对氧化过程影响较大的六类因素，探讨了该技术的发展方向。

Abstract： In response to the policy of “zero discharge of industrial wastewater”, the catalytic ozonation technology is usually used in the advanced treatment of brine wastewater in the coal-chemical industry to make the effluent COD meet the requirements of following processes such as the membrane craft and evaporation crystallization to ensure the overall stable operation of the equipment. The reactive mechanism of the organism degrading by the catalytic ozonation, the classification of this technology and reactive ways of each, the materials commonly used to prepare the catalyst under current research level were mainly introduced.The merits and demerits of different materials to prepare the catalyst; were elaborated. Six major factors in the oxidation process were summaried. The prospect of the catalytic ozonation technology was explored.

Key words： brine wastewater ozone catalyst oxidation factor
