摘　　要：本文对无机陶瓷膜错流过滤澄清中药提取液进行研究。考察了澄清效果；研究了操作压差、流速等条件对膜通量的影响；对污染机理进行了初步分析；采用多种清洗剂交替清洗使膜通量得到很好的恢复。研究表明，采用陶瓷微滤膜进行中药提取液的澄清是一极有前途的新技术。In this paper, clarification of Traditional Chinese Medicine extract by ceramic microfiltration membrane was studied. The effect of operating parameters, such as filtration pressure, crossflow velocity on membrane flux was investigated. Fouling mechanism of ceramic microfiltration membrane was analyzed with hydraulic resistance model. Membrane was cleaned by using some chemical agents, and the restorations of flux were satisfactory. The results show ceramic microfiltration technology is a promising new one for clarification of traditional Chinese medicine extract.
