description The invention relates to a calcium alginate composite membrane with biofilm resistance and a preparation method and application thereof.The composite membrane is obtained by coating the surface of a micro-filtration membrane with a micro-nano coating and has super-hydrophilic/underwater super-oleophobic performance, the micro-nano coating is a composite material of chitosan, silver nanoparticles and calcium alginate, and the silver nanoparticles are silver nanoparticles. The micro-nano coating has a fibrous three-dimensional porous structure, and silver nanoparticles are densely distributed on the surface and inside the coating. According to the calcium alginate composite membrane with the anti-biofilm performance, the micro-filtration membrane provides a micron hole structure, and the silver nanoparticles wrapped by the chitosan provide a nano structure, so that the prepared composite membrane has super-hydrophilic/underwater super-oleophobic performance, good antibacterial performance and good anti-biofilm
