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 ?m Al_2O_3 and 50 nm ZrO_2 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.
