| 摘 要： | 研究了木聚糖碱抽提液超滤过程中膜面污染的形成和发展过程,以及膜面污染可逆性;分析了膜面清洗方法、反冲洗对溶剂透过率恢复的影响。结果表明:操作压力越低,进料速度越大,越有利于减轻膜面污染;膜面污染为部分可逆;4% NaOH溶液能有效地恢复溶剂透过率,而反冲洗只能部分地恢复溶剂透过率。

| Abstract: | The membrane fouling and its reversibility during ultrafiltration of xylan extractives were investigated,and the method to clean the fouled membrane was examined.It was found that lower transmembrane pressure and higher feeding velocity were favorable to alleviate the membrane fouling,that 4% NaOH solution could efficiently recover the solvent flux through the membrane,but backwash could only regain the part of the solvent flux. |
