The invention discloses a treatment method of resin regeneration wastewater, which comprises the following steps: adding calcium oxide into the resin regeneration wastewater to remove part of sulfate radicals, phosphate radicals, magnesium ions and the like in the wastewater and reduce the subsequent addition amount of aluminum salt; adding aluminum nitrate to remove residual sulfate radicals; filtering to obtain filtrate and filter residues, filtering the filtrate by adopting a reverse osmosis membrane, intercepting residual ions in a system, evaporating and concentrating intercepted liquid, further using the intercepted liquid and solid residues as a plant fertilizer, and recycling reverse osmosis membrane permeate liquid for preparation of resin regeneration liquid, so that comprehensive treatment and resource utilization of the resin regeneration wastewater are realized.
