The invention discloses a modification treatment method of ZSM-5 zeolite. The method comprises the following steps of: adding a certain proportion of aqueous alkali and a low molecular weight organic solvent into ZSM-5 zeolite, performing ultrasonic treatment on the system, transferring to an enclosed system for alkali treatment, and finally separating and drying to obtain the modified ZSM-5 zeolite.
