The invention discloses a treatment method adopting cellulose ether solvent to recycle vinasse, which comprises the following steps: during the production process of cellulose ether, an organic solvent medium is adopted to distill the vinasse generated during the recycling process to a supersaturated solution or until the moisture is completely evaporated to dryness, ethyl acetate is adopted to perform first extraction so as to filter and separate lost cellulose ether, the ethyl acetate is distilled for recycling, and the leftover after distillation is a secondary product of etherifying agent; first extraction is performed on the subnatant, quantitative hydrogen chloride is added for acidification, then ethyl acetate is added for secondary extraction so as to recycle acetic acid or glycollic acid, the ethyl acetate is distilled and recycled for recycling, the leftover after distillation is acetic acid or sodium glycollate, secondary extraction is performed on the subnatant, alkali is adopted for neutralization, concentration is performed continuously, and sodium chloride is filtered and recycled. According to the invention, as less organic solvent in the concentrated solution is evaporated, and the organic solvent can be used together with a washing solution in the production technology of cellulose ether, zero emission of the three wastes during the production process of the cellulose ether is realized, waste material is changed into things of value, and higher economic benefit is obtained.
