【摘要】 目的:摸索无机陶瓷膜分离地龙匀浆液中药效物质的最佳操作条件。方法:以膜通量为指标,筛选合适的膜材质,优化压力、温度、浓度等操作条件。结果:显示膜通量随过滤压差、温度增加而呈现上升趋势,随浓度的上升而下降。结论:通过比较膜通量的大小和膜通量的衰减速度,分级分离时一级膜管选择0.2μm Al2O3、二级膜管选择50 nm ZrO2,最佳操作条件:0.15 mPa、50℃、33.3%的料液浓度。更多还原

【Abstract】 AIM: To aim to seek the best operation conditions of the inorganic ceramic membrane in the separation of effective matters from the homogenate of earthworm. METHODS: The homogenate flux was adopted as index,to select the membrane material,filter pressure、homogenate temperature and concentration. RESULTS: The experiment showed that the filter flux had a significant positive correlation with pressure difference and liquid temperature,and negative correlation with liquid concentration. CONCLUSION: In the separation of earthworm homogenate,0.2 μm Al₂O₃ and 50 nm ZrO₂ film pipe were respectively selected as primary and secondary separating unit on the condition of 0.15 mPa pressure,50 ℃ and 33.%（w/w） homogenate concentration.更多还原
