The present application relates to a method for a resourceful treatment of waste carbon fiber wind turbine blades. The method comprises the following steps: (1) separating balsa wood from waste carbon fiber wind turbine blades, then pyrolyzing same, and modifying same with an alkali liquor, so as to obtain a pyrolyzed balsa wood catalyst; and (2) subjecting the waste carbon fiber wind turbine blades from which the balsa wood is separated and the pyrolyzed balsa wood catalyst obtained in step (1) to a microwave co-pyrolysis treatment, so as to obtain pyrolysis gas, pyrolytic oil and pyrolytic carbon.
