摘    要:利用湿式相转化方法制备TiO2/聚苯砜(polyphenylsulfone,PPSU)/聚醚亚硫胺(polyetherimide,PEI)催化膜应用于水中腐植酸(humic acid,HAs)的去除及积垢机理研究。结果表明,随着亲水性PEI比例增加,光催化膜的纯水通量和HAs的过滤通量越大,去除效率越低;且随着光照时间的延长去除效率越趋于稳定,且有回复的现象。在0.2MPa操作压力下,制备的TiO2/PPSU/PEI (1%/50%/50%)膜具有最佳的可逆阻抗力比例(Rc/Rt=48.24%);其渗透通量、HAs去除效率及反洗后通量分别为34.0L/(m2·h)、63.2%及22.5L/(m2·h),具有较佳的通量及HAs去除效率。

Abstract:The preparation of TiO2/polyphenylsulfone (PPSU)/polyetherimide (PEI) photocatalytic membrane by using wet phase transformation method was studied. The control of humic acid (HAs) and fouling mechanism from wastewater were also investigated. Results showed that the increasing of PEI ratio, water and filtration flux of humic acid were higher and the removal efficiency of humic acid was lower. With the extension of illumination time, the removal efficiencies were tended to stable and there was a recovery phenomenon. Under 0.2 MPa operating pressure, the prepared TiO2/PPSU/PEI photocatalytic membrane (1%/50%/50%) were the good reversible resistance ratio (Rc/Rt=48.24%), flux and HAs removal efficiency. The permeate flux, photocatalytic removal efficiency of HAs and backwash flux were 34.0L/(m2·h)、63.2% and 22.5L/(m2·h), respectively.
Keywords:titanium dioxide (TiO2)  photocatalytic membrane  humic acid (HAs)  polyphenylsulfone (PPSU)  polyetherimide (PEI)
