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. In the present application, by subjecting the tar generated during the process of microwave co-pyrolysis to in-situ catalytic cracking, the subsequent coking problem of a pyrolysis device is ameliorated; and compared with conventional pyrolysis conditions, the energy consumption of pyrolysis is reduced, and the content of pyrolytic oil is reduced, which are conducive to the rapid implementation of resource recycling during the subsequent treatment process of the waste carbon fiber wind turbine blades.
