Abstract: The invention is related to a super-hydrophilic/underwater super-oleophobic attapulgite separation membrane, and a preparation method and use thereof. Monodispersed hydrophilic nanoparticulates are loaded on a surface of nanoparticles, to obtain a super-hydrophilic nanocomposite material with a micro-nanostructure. The nanocomposite material is dispersed in a mixed aqueous solution of polyacrylamide and methyl cellulose, to obtain a membrane-forming slurry after vigorous stirring. A disc-shaped porous support is infiltrated with water and placed on a horizontal surface, and then a certain volume of the membrane-forming slurry is slowly and uniformly drip-coated on a surface of the support, dried and sintered to obtain a super-hydrophilic/underwater super-oleophobic microfiltration membrane layer.
