Treatment method of M resin

The invention belongs to the technical field of waste treatment, and discloses a treatment method of M resin. The treatment method comprises the following steps: (1) soaking M resin with a solvent to obtain a mixture, then carrying out suction filtration to obtain a solid insoluble substance and a first filtrate, and drying the solid insoluble substance; (2) mixing the solid insoluble substances in the step (1) with alkali liquor, then carrying out suction filtration to obtain solid residues and second filtrate, and drying the solid residues; and (3) mixing the second filtrate in the step (2) with an acid solution to obtain a turbid liquid, filtering to obtain a filter cake and a third filtrate, washing the filter cake with water, and carrying out suction filtration to obtain a solid product. According to the treatment method, M resin does not need to be incinerated, the environmental protection property is good, the treatment efficiency is high, the treatment cost is low, even the M resin can be recycled, th
