摘要

制备了亲水微滤膜和疏水微滤膜两种类型的平板膜,用于处理苯酚污染的水溶液。采用聚砜、聚氧聚乙烯、二甲基乙酰胺和n -甲基-2-吡咯烷酮四种合成聚合物制备膜。利用扫描电子显微镜对所制备膜的顶表面和横截面图像进行了物理表征。以蒸馏水和苯酚污染水为研究对象,根据压力、苯酚浓度和温度等变量对膜的通量结果进行了评价。同时,对苯酚污染的水溶液进行了过滤性能评价。结果表明,随着压力和温度的升高,通量增大,随着苯酚浓度的增加,通量减小。蒸馏水的结果远远高于被苯酚污染的水。亲水性蒸馏水通量为52.18 ~ 73.15 L/m2/h,疏水性蒸馏水通量为72.27 ~ 97.46 L/m2/h,亲水性蒸馏水通量为26.58 ~ 61.55 L/m2/h,疏水性蒸馏水通量为29.98 ~ 80.55 L/m2/h。同时,亲水性膜对苯酚溶液的去除率为60%,疏水性膜对苯酚溶液的去除率仅为45%。疏水膜具有高通量、低排斥的特点。因此,通过该膜的输运比通过亲水性膜的输运更接近于具有粘性行为;相比之下,亲水性膜的渗透性较小,因为孔隙大小降低了粘性流动机制。

The Performance of Microfiltration Using Hydrophilic and Hydrophobic Membranes for Phenol Extraction from a Water Solution
Two types of membranes, for hydrophilic and hydrophobic microfiltration, were prepared as flat sheets to treat a phenol-contaminated water solution. The membranes were fabricated using four synthetic polymers: polysulfone, polyethylene oxide, dimethylacetamide, and N-methyl-2-pyrrolidone. Scanning electron microscope measurements of the top-surface and cross-section images of the produced membranes were used to characterize them physically. Distilled water and water contaminated with phenol were used to evaluate the membrane’s performance based on the flux results depending on pressure, the concentration of phenol, and temperature variables. Meanwhile, the rejection performance was evaluated using the phenol-contaminated water solution. The results show that the flux increased with increases in pressure and temperature and decreased with increases in phenol concentration. Distilled water gave far higher results than water contaminated with phenol. The flux of distilled water ranged from 52.18 to 73.15 L/m2/h for the hydrophilic type and from 72.27 to 97.46 L/m2/h for the hydrophobic type, whereas the flux of water contaminated with phenol solution ranged from 26.58 to 61.55 L/m2/h for the hydrophilic type and from 29.98 to 80.55 L/m2/h for the hydrophobic type. Meanwhile, the phenol solution’s rejection was 60% when using a hydrophilic membrane, whereas it was only 45% when a hydrophobic membrane was used. The hydrophobic membrane showed high fluxes and low rejection. Thus, transport through this membrane is closer to having viscous behavior than that through the hydrophilic membrane; in contrast, the permeability through the hydrophilic membrane is less because the pore size decreases the viscous flow mechanism.
