Adsorption-catalytic oxidation degrading method for phenol in waste water

The invention relates to an adsorption-catalytic oxidation degrading method for phenol in waste water, and belongs to the technical field of water treatment. The method is characterized in that active carbon fibers which are loaded with ferroferric oxide are used as an adsorption agent and filled in an adsorption tower so as to adsorb the waste water containing phenol; hydrogen peroxide aqueous solution is added into the adsorption tower, air is also blown into the adsorption tower, and the mixed system is oxidized for 1h to 3h, so that the adsorption agent is regenerated, and then the waste water containing phenol is inputted to be circularly adsorbed. By adopting the method, the desorption regeneration problem of the active carbon fibers after adsorbing phenol, the degradation problem of the desorbed phenol and the high energy consumption problem of the catalytic wet-type hydrogen peroxide oxidation technology in treating the waste water containing a great amount of phenol can be solved. The method has the advantages of simple process, easiness in operation, no secondary pollution on the environment and the like.
