摘　　要：设计了一种具有光热转换功能及PDS活化性能的聚苯胺/碳纳米管膜,利用其光热转换能力高效活化PDS增强水处理效率。通过扫描电子显微镜、红外、能谱分析、X射线衍射、拉曼等对膜的物理化学特性进行了系统表征,以苯酚为目标物考察了催化膜的性能。光照条件下(波长大于400 nm),催化膜的表面温度、通量和污染物去除效率均显著提升,该催化膜可以在6 834.2 L/(m^(2)·h·MPa)的高通量下实现88.5%的苯酚去除,效率是没有光照条件下催化膜性能的3.1倍,是单独膜分离过程的22.7倍。聚苯胺含量的增加和水力停留时间的延长有助于提高膜性能。A polyaniline/carbon nanotube membrane with photothermal conversion function and PDS activation ability was designed, and its PDS activation efficiency for water treatment could be largely improved by its unique photothermal conversion ability. The physicochemical properties of membrane were tested by scanning electron microscopy, Fourier transform infrared spectroscopy, X ray diffraction and Raman spectroscopy. As the target pollutant, the phenol was chosen to evaluate the performance of catalytic membrane. The membrane permeability and pollutant removal were obviously improved under the light irradiation ( λ >400 nm). The phenol could be removed 88.5% by catalytic membrane at a high flux of 6 834.2 L/(m^(2)·h·MPa), which was 3.1 and 22.7 times higher than that of catalytic membrane without light irradiation and the membrane filtration alone, respectively. The membrane performance could be enhanced with the increase of polyaniline content and hydraulic retention time.
