The invention discloses an advanced oxidation organic wastewater treatment system and method based on resource utilization of waste lithium iron phosphate materials. The system comprises an advanced oxidation reaction pool, a detachable LFP filler cavity, an [S(IV)] liquid storage tank, a wastewater pool, a water outlet pool and the like, wherein the LFP filler cavity is assembled in the advanced oxidation reaction pool, wastewater and a sulfite solution are pressurized respectively, mixed and conveyed to the bottom of the advanced oxidation reaction pool through a wastewater inlet pipeline, then the wastewater passes through the LFP filler cavity, and wastewater purification is realized on the basis of species with high oxidation activity generated by inducing S(IV) by LFP. According to the invention, the waste power battery LFP material with low value is smartly recycled through the thought of'treating waste with waste; and the filler cavities can be flexibly reduced or increased according to wastewater tre
