NOVELTY - Integrated technique comprises preprocessing the glyphosate mother liquor, carrying out integrated membrane separation and oxidation process, cooling and crystallizing the mother liquor, separating out phosphate, and filtering to obtain phosphate, combining the permeate liquid of the separation system with the clear liquid obtained by cooling crystallizing and separating, adding calcium hypochlorite solution, and filtering to obtain phosphate, filtering the filtrate, processing the permeate liquid obtained by the reverse osmosis membrane in a biochemical processing system, and discharging.    USE - The method is useful for recycling glyphosate mother liquor (claimed).    ADVANTAGE - The method adjusts the amount of the mother liquor conveyed to the membrane separation system based on the sales status of the aqueous agent, adapts to the market demand, controls the cost, avoids the influence of device maintenance, and guarantees the normal operation of the glyphosate production device.    DETAILED DESCRIPTION - Integrated technique comprises: (a) preprocessing the glyphosate mother liquor; (b) carrying out integrated membrane separation by conveying the preprocessed glyphosate mother liquor to an integrated membrane separation system according to the weight of 1-99%, and using the closure liquid which contains glyphosate and has not passed through the integrated membrane for producing ammonium glyphosate aqueous agent (33%); and carrying out oxidation process by conveying the balance amount of the glyphosate mother liquor after conveying to the separation system to an oxidation system, oxidizing the impurity containing phosphorus to phosphate radical ion, and oxidizing nitrogenous organic impurity to ammonia radical ion by using an oxidant; (c) cooling and crystallizing the glyphosate mother liquor oxidized in the step (b), separating out the phosphate and filtering to obtain phosphate which is used for producing phosphate fertilizer; (d) combining the permeate liquid of the separation system with the clear liquid obtained by cooling crystallizing and separating, adding calcium hypochlorite solution for further removing the organic phosphorus, and filtering to obtain phosphate which is used for producing phosphate fertilizer; (e) filtering the filtrate of the step (d) through a nanofiltration membrane, filtering to obtain permeate liquid, filtering through a reverse osmosis membrane, adopting closure liquid which has not passed through the reverse osmosis membrane as sodium chloride solution, and adopting the impurity with phosphate and nitrogen content below 1 parts per million for producing chloralkali; and (f) conveying the permeate liquid obtained by processing in the reverse osmosis membrane to a biochemical processing system, where the permeate liquid salt content is less than 1%, the chemical oxygen demand (COD) is less than 1200, and matches with the water inlet requirements of the biochemical processing system, and processing and discharging when the standard is attained.
