Thetheoreticalanalysiswasalsogiveninordertoexplainthoseperformancedifferencesoftwomembranesinthispaper. TheevaluationresultsindicatedthatthePPmembranepossessedthecharacteristicsofgoodhy-drophobicbehavior, largeoxygenmasstransfercoefficient, betterresistancetomembranefoulingandlowcost. Therefore, thePPmembraneishighlysuitabletothemembraneabsorptionprocesses. Keywords: membraneabsorption; polypropylenemembrane; polyvinylidenedifluoridemembrane; masstrans-fer; porosity; hydrophobicity; membranefouling \easy to produce fruits of industrialization and the universal significance of the transformation results. On a national, provincial Ministry of Natural Science Foundation project, priority scientific and technological projects related papers reported. \12 yuan per copy, the annual 144 yuan.
