The invention relates to a method for treatment of glutamic acid processing waste liquor in monosodium glutamate production, and the method applies the bipolar membrane electrodialysis technology to reduce concentrations of acid ions and NH4+ ions in ion exchange waste liquor of glutamic acid, simultaneously, corresponding acids and NH3 are regenerated respectively. The method in the invention effectively overcomes the defects that the ion exchange waste liquor generated in the prior production of glutamic acid is difficult to treat and utilize, in addition, the method realizes resource utilization of the ion exchange waste liquor and clear production. |
