The invention discloses a recycling method for cellulose ether production wastewater, relates to the technical field of production wastewater treatment, and provides the following scheme aiming at the problems that an existing recycling method for the production wastewater is relatively large in limitation, causes resource waste, increases the treatment cost of hazardous wastes and causes harm to the environment. The method comprises the following steps: S1, cooling the cellulose ether production wastewater resource, and filtering after cooling to remove visible particles; s2, feeding the filtered cellulose ether production wastewater resources to a membrane separation system to generate the concentrated liquid and filtrate through membrane separation; s3, performing evaporation, flash evaporation / cooling, solid-liquid separation and drying on permeate liquid after membrane separation to generate condensate water, crystal salt and mother liquor; s4, mixing the concentrated liquor and the mother liquor, treating the liquid by adsorptive resin, and returning the liquid to the membrane separation system after adsorption. The wastewater recycling method is low in treatment difficulty, and the additional value of resources is increased, so that the cost is reduced, and the discharge of mother liquor is reduced.
