Summary:The invention discloses a preparation method of a porous quartz ceramic filter material, which comprises the following steps: by using high-purity quartz sand as a raw material and a silane coupling agent as a surface modifier, preparing a silane coupling agent ethanol solution, spraying the silane coupling agent ethanol solution into high-speed stirred quartz sand in a mist form, and stirring anddrying to obtain surface-modified quartz sand; by taking quartz sand as a raw material and silica sol as a binder, uniformly stirring surface-modified quartz sand and a silica sol aqueous solution, and granulating to obtain a granulated material with a certain granularity; and preparing a porous quartz ceramic green body from the granulated material through compression molding, and calcining thegreen body at 1100-1300 DEG C to obtain the porous quartz ceramic filter material. The porous quartz ceramic filter material prepared by the invention is high in structural strength, not easy to damage, multiple in open pores,
