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
