| Abstract: | A kind of green water treatment technique- vacuum membrane distillation (VMD) is used to treat polyphenol pharmacy wastewater and recover ethanol thereby. The effect of the experiment condition on the membrane separation performance is investigated. Under optimized conditions, the concentration of the recovered ethanol solution is 34.5%, the ratio of polyphenol mixture interception is 99.67%. Theoretical analysis and experiment data show that as a new green technique of wastewater treatment, VMD has large flux, low cost, good separation effect and will play an important role in treating industrial organic wastewater and recovering organic solvent. |
