采用阳离子Gemini表面活性剂（CG）和截留分子量为10kDa的聚醚砜（PES）平板膜，对胶束强化超滤处理含酚废水进行了综合研究。考察了GMEUF实际应用中各因素（CG浓度、非离子表面活性剂摩尔分数、电解质浓度和温度）对苯酚和表面活性剂截留率、渗透通量和二次阻力的影响。结果表明，随着进料CG浓度和非离子表面活性剂摩尔分数的增加，苯酚的截留率显著提高。相反，电解质浓度和温度对苯酚截留率有负面影响。此外，进料CG浓度和非离子表面活性剂摩尔分数的增加导致渗透通量的降低和二次阻力的增加显着。这些结果表明，具有特殊结构的CG表面活性剂在胶团强化超滤处理含酚废水中具有广阔的应用前景。
Comprehensive studies were carried on the micellar-enhanced ultrafiltration of phenol for the treatment of phenol wastewater with the help of cationic Gemini surfactant (CG) and Polyethersulfone (PES) flat sheet membranes of a molecular weight cut-off of 10kDa. The effects on the retention (phenol and surfactant), permeate flux and secondary resistance of various factors in the practical application of GMEUF were investigated including feed CG concentration, mole fraction of nonionic surfactant, electrolyte concentration and temperature, respectively. The results presented that the retention of phenol kept evidently increasing with the augment of the feed CG concentration and mole fraction of nonionic surfactant. On the contrary, electrolyte concentration and temperature had a negative influence on the phenol retention. Besides, the addition of feed CG concentration and mole fraction of nonionic surfactant led to the decrement of the permeate flux and enhancement of secondary resistance significantly. These results demonstrated that CG surfactant with exceptional structure had brightly application prospect for the treatment of phenol wastewater in micellar-enhanced ultrafiltration.
