The invention discloses a preparation method of an adsorption photocatalytic separation multifunctional membrane based on a polydopamine bionic coating, wherein the multifunctional membrane is used for performing more than one layer-by-layer modification on the surface of a base membrane, so that the problem that a catalyst is covered or functional particles are easy to fall off in other modification methods is avoided, photocatalytic nanoparticles can be exposed to a light source as far as possible, and adsorption enrichment of nano polysaccharide fibers and GO/TiO are realized 2 The catalytic degradation and the membrane separation are carried out synchronously, and the high-efficiency treatment of the printing and dyeing wastewater is realized. Compared with the prior art, the preparation method is simple, easy to operate, economical, efficient and easy to industrialize. |
