摘要:
以氧化石墨烯(GO)掺杂聚偏氟乙烯(PVDF)制备的GO/PVDF平板膜为研究对象,研究膜的过滤特性和过滤阻力分布,并考察不同孔径的膜对造纸废水的处理效果。结果表明:随着GO掺量的增大,膜的亲水性以及抗污染性增强,膜的热稳定性增强。添加2% GO的膜的接触角为63.1°,纯水通量和牛血清蛋白(BSA)通量分别达到595 和121 L/(m2·h),对BSA的截留率为74%; BSA溶液过滤过程中表面沉积阻力占主导,物理清洗后,膜的纯水通量恢复率低于55%; 化学清洗后,膜的纯水通量恢复率大于96%。大孔径(1和2 μm)膜处理造纸废水,因膜孔堵塞,通量迅速衰减,小孔径(0.15、0.3和0.55 μm)膜的稳定通量随孔径的增大而增大。
Abstract:
Graphene oxide(GO)blended polyvinylidene fluoride(PVDF)membranes were explored to investigate the filtration behavior and resistance distribution.Papermaking wastewater was treated with the membranes in various mean pore sizes.Results showed that the hydrophilicity,anti-fouling property and thermostability were enhanced with the increase of GO dosage. When the content of GO was 2%,the contact angle of the membrane was 63.1°,pure water flux and bull serum albumin(BSA)flux were 595 and 121 L/(m2·h),respectively.The retention of the membrane towards BSA solution was 74%.The surface deposition resistance was dominant during BSA solution filtration,and the recovery ratio of pure water flux of the contaminated membrane was smaller than 55% after physical cleaning.However,the figure was above 96% after chemical cleaning.During papermaking wastewater treatment,the flux of membranes with large mean pore sizes(1 and 2 μm)decreased dramatically because of pore blocking. Owing to enhanced anti-fouling ability,the stable flux of membranes with smaller ones(0.15,0.3 and 0.55 μm)increased with increasing mean pore sizes.
