A method and production system for removing impurities from a taurine mother liquor and recovering the taurine mother liquor recovery. The method and system can be used in an ethylene oxide production process for taurine and the treatment of the last mother liquor of taurine. The last mother liquor of taurine is ion-exchanged through an anion exchange resin; then the anion exchange resin is eluted and regenerated with alkaline solution, and the outlet material liquor is collected; (b) the collected outlet material liquor is subjected to ammonia mixing treatment, and the mother liquor is generated after the impunity is removed and the separation of the solid and liquor; (c) the generated mother liquor is then returned to the ammonolysis step of taurine production. After the last mother liquor of taurine is treated by the anion exchange resin, more impurities in the last mother liquor can be removed, and salt is further removed by ammonia mixing treatment to generate a pure taurine mother liquor, thereby realizing the recovery of the mother liquor and improving the product yield.
