The invention relates to a treatment method for glycerine concentrated sewage of stearic acid production. The treatment method is aimed at the glycerine concentrated sewage of industrial stearic acid production. The glycerine concentrated sewage in a raw water collection tank sequentially flows through an MBR (Membrane Bioreactor) filtering system, a primary RO (Reverse Osmosis) treatment system and a secondary RO treatment system, a concentrated water output end of the MBR filtering system is connected with an input end of a biochemical treatment system, a plain water output end of the MBR filtering system is connected with an input end of the primary RO treatment system, a concentrated water output end of the primary RO treatment system is connected with an input end of the secondary RO treatment system, and a plain water output end of the secondary RO treatment system is connected with the input end of the primary RO treatment system. The treatment method has the beneficial effects that the water quality of produced water is good, the production process is stable, the treatment cost is low, and the treatment method is environmentally friendly.
