The invention discloses a photocatalytic nanofiber membrane and sewage equipment. The raw materials of the photocatalytic nanofiber membrane include, in parts by weight, 3-5 parts of nanocellulose, 15-20 parts of polyvinyl alcohol, and 0.3-20 parts of chitosan. 0.8 parts, 0.1-0.3 parts of cetyl trimethyl ammonium bromide and 150-200 parts of distilled water; the invention organically combines nano-cellulose and polyvinyl alcohol to prepare a high-performance photocatalytic nano-fiber film, which can efficiently Filters pollutants such as bacteria, viruses, heavy metal ions and other pollutants in sewage, and the treated wastewater can meet the environmental requirements and be discharged directly; the photocatalytic nanofiber membrane also has the advantages of good surface hydrophilicity, long service life, easy cleaning and recycling, etc. advantage. |
