To improve the hydrophobicity and maintain a high permeability of the membrane, the molecular simulation of heat and mass transfer and pollution [pollutants were humic acid (HA), L-cysteine (LC) and Ca2+] resistance experiment of the prepared graphene oxide-polyvinylpyrrolidone/polyvinylidene fluoride (GO-PVP/PVDF) composite membrane were carried out. Then, the heat and mass transfer model of the membrane was established by using Materials Studio (MS) software. The higher content of GO resulted in the less cracks on the membrane surface. The permeability and thermal conductivity of the composite membrane with the����ȫվAPP left and right stacking mode was the best, while the performance of the composite membrane with the top and bottom stacking mode was the worst. The hydrogen bonding energy (Eel) was negative, which resulted in negative interaction energy between pollutants and the membrane surface, and was the main force for pollutant enrichment on the membrane surface. Furthermore, the addition of Ca2+ aggravated the membrane fouling.类似文献/References:[1]蒋宝军,孙一文,王新培,等.磁性TiO2/GO复合催化剂处置垃圾渗滤液实验研究[J].中国给水排水,2022,38(3):99.
