The invention relates to the technical field of textile wastewater treatment, in particular to a nanofiber membrane, a preparation method and application thereof in dye wastewater treatment. The nanofiber membrane is prepared by taking cellulose acetate as a main membrane material through an electrostatic spinning method, has high porosity and large specific surface area, is exposed with a large number of amino and carboxyl active groups on the surface, can adsorb toxic and difficultly-degraded water-soluble substances in dye wastewater, still has high dye adsorption rate in a high-temperature environment, and is excellent in mechanical property and alkali resistance. |
