摘要
本文采用膜蒸馏技术分离聚酯废水中的乙醛,通过实验比较了聚四氟乙烯微孔膜和聚偏氟乙烯微孔膜的分离性能,并考察了膜室温度、进料乙醛浓度和冷侧真空度对聚四氟乙烯微孔膜分离性能的影响。
Recovery of acetaldehyde from PET waste Water has been studied by membrane distillation technique. The separation performance of the PTFE microporous membrane and PVDF microporous membrane were compared by experiment. Influence of separation process operation conditions on separation effect was investigated.
