摘　　要：通过研究操作压强、错流速度等参数对膜的通量的影响,测定了氧化锆(ZrO2)陶瓷动态膜对Lyocell纤维溶剂的回收效果;提出了优化的操作条件;对回收过程中的膜污染,采用了物理方法对膜进行反冲洗。In this paper, the effect of reclamation of Lyocell Cellulose Solution by ZrO2 ceramic dynamic membrane was investigated through studying the influences of the operating parameters, such as filtration pressure, crossflow velocity on membrane flux. The optimized operating conditions were advanced. Aiming at the membrane fouling appeared in reclamation process, a physical method was utilized to wash the membrane.
