| 摘 要： | 目的:研究无机陶瓷膜微滤黄芪水提液的污染机制,寻找有效的膜污染防治手段。方法:通过对不同孔径的氧化锆膜在膜微滤过程中的阻力分布、高分子去除率、物理化学参数变化等的测定,分析污染物的存在状态或位置以及形成规律,同时采用反冲、超声2种物理手段强化膜过程,从而探索膜污染的防治方法。结果:0.2μm ZrO2微滤黄芪水提液时污染度较高,达44.9%;堵孔阻力和浓差极化阻力是主要的过滤阻力,表面沉积阻力随膜孔径的减小而增大;微滤后药液浊度显著降低,pH和黏度变化均较小,0.2μm ZrO2膜对电导率的降低作用略高于0.05μm ZrO2膜管。0.2,0.05μm ZrO2膜均对果胶的去除作用最为显著。超声强化膜过程手段更适用于本体系,其通量提高率达41.7%。结论:优化膜过程工艺参数,采用适当膜污染防治手段可以减少膜的污染,使膜的性能有较大恢复,提高滤过效率。
