Abstract
A method for treating waste gases containing low-concentration volatile organic compounds (VOCs) based on combination of adsorption and in-situ temperature-varying catalytic ozonation, relating to treatment of organic waste gases. In the method, a VOCs-containing waste gas is fed to an adsorption bed for enrichment, which includes a low-temperature regeneration process and a high-temperature regeneration process. A catalyst with high adsorption capacity and catalytic activity is loaded on the adsorption bed.
