【摘要】 为了消除污染、控制废水水质,开发了电渗析处理糠醛废水的新方法。中间试验表明,通过电渗析可以回收浓度为20%的乙酸。再经过萃取、精馏工艺得到工业一级的乙酸,废水可回用。更多还原

【Abstract】 To eliminate pollution and contol water quality,a new method of recover-ing acetic acid from furfural wastewater containing 1—2.5w% acetic acid by elec-trodialysis has been developed.In the pilot plant-scale operation,concentrationof recovered acetic acid reached 20%wt.The quality of the wastewater is improvedand can be reused.更多还原
