Integrated process for recycling glyphosate mother liquor

The purpose of the invention is to provide an integrated process for processing mother liquor generated in the process of preparing glyphosate to solve the problems of higher cost and resource solution in glyphosate mother liquor processing. The process comprises the steps of: pre-treatment of mother liquor, integrated film separation, oxidation treatment, crystal separation, chemical phosphorus removal, film separation dechlorination and biochemical treatment. According to the sales condition of water aqua, the dosage of the mother liquor going into a film separation system is adjusted; the market demand is adapted; meanwhile, the cost is controlled; the influences of device maintenance and the like are avoided, and normal operation of a glyphosate production device is guaranteed. The glyphosate obtained from integrated film separation can be used for producing 33% of glyphosate ammonium salt agent; organic phosphorus obtained from crystal separation and chemical phosphorus removal can be applied to phosphate fertilizer production; sodium chloride solution obtained from film separation can be applied to chlor-alkali production, and the other parts can go into biochemical treatment and be discharged with standards.
