Abstract

A method for processing an organic solvent-containing air capable of being operated in spite of a rapid fluctuation of the concentration of organic solvents in the air to be processed and capable of using a combustion furnace exhaust gas as an air for regenerating dehumidifying member is provided. The method comprises carrying out simultaneously and continuously a dehumidification step (a), an adsorption-removing step (b), an adsorbing member-regeneration step (c), a combustion step (d), and a dehumidifying member-regeneration step (e) comprising mixing the adsorption-treated air produced in the adsorbing-removing step (b) with a combustion furnace exhaust gas produced in the combustion step (d) to obtain a mixed gas, decomposing the organic solvents in the mixed gas by oxidation, and causing the resulting purified gas to flow through the dehumidifying member which has adsorbed moisture, thereby regenerating the dehumidifying member.
