Recycling method of surface treatment wet process cleaning fluid

The invention relates to a recycling method of surface treatment wet process cleaning fluid, comprising the following steps: pre-processing to-be-processed cleaning fluid by using a carbon fiber filter and an ozone generator, and removing impurities and hydroxy organics from the cleaning fluid; performing reverse osmosis treatment by using a nano molecular level reverse osmosis film, and forming concentrated solution containing high sodium ions, and penetrating fluid containing low sodium ions; performing post-level treatment by using a post-level treatment unit, absorbing anions and cations, generating regenerative deionized water with grade of deionized water so as to recycle; storing concentrated solution by using a concentrated solution storage tank, performing electrolyte dialysis treatment by using a bipolar electric dialysis unit to generate dialysis water, and conveying the dialysis water to the molecular level reverse osmosis film. Therefore, the method provided by the invention can increase recyclin
