| titleOfInvention | A kind of method of lactic acid evaporation condensed water recovery |
| abstract | The invention discloses a method for recovering lactic acid evaporation condensed water. It includes the following steps: S1, pretreatment, pretreatment of lactic acid evaporation condensed water; S2, membrane concentration, lactic acid concentration is carried out on the pretreated lactic acid evaporation condensed water using a lactic acid membrane concentration system to obtain concentrated lactic acid and concentrated membrane clear water Phase water, concentrate lactic acid to the lactic acid production line to produce lactic acid products; S3, membrane purification, adjust the pH of the concentrated membrane clear phase water obtained in step S2 to neutrality and then use a membrane purification system to purify, and obtain membrane clear phase water and organic acid salts after purification dope. The invention can realize the recovery and utilization of lactic acid in the evaporation and condensate water of lactic acid, and enrich and concentrate a small amount of residual lactate as the raw material for organic fertilizer production. Waste of resources and environmental pollution, while improving economic efficiency and achieving zero emissions. |
