Beschreibung
Zusammenfassung:	The invention belongs to the technical field of photocatalytic materials, and relates to a composite nanofiber membrane as well as a preparation method and application thereof. The preparation method comprises the following steps: preparing a polyacrylonitrile/bismuth tungstate nanofiber membrane by adopting an electrostatic spinning method, loading an aniline polymer on the basis of the polyacrylonitrile/bismuth tungstate nanofiber membrane, and preparing the composite nanofiber membrane which takes polyacrylonitrile as a fiber membrane framework and is loaded with bismuth tungstate crystals and the aniline polymer. The composite nanofiber membrane disclosed by the invention has excellent photocatalytic performance and good reusability, has a remarkable catalytic effect on organic dyes such as methylene blue, can be applied to photocatalytic wastewater treatment, and is beneficial to environmental protection and pollution control. 本发明属于光催化材料技术领域，涉及一种复合纳米纤维膜及其制备方法与应用。本发明采用静电纺丝法制备聚丙烯腈/钨酸铋纳米纤维膜，在此基础上负载苯胺聚合物，制备得
