[0030] The filtration membrane has high porosity and strong hydrophilicity. Convex formed by multiple shark-scale shield micro-blades on the filter membrane of shark-scale shield micro-blades
[0032] The initial adhesion of free bacteria on the surface of the membrane material is a necessary condition for the formation of biofilms to cause membrane fouling. Book
[0040] A plurality of hexagonal shield groups 2 are complementary and connected along the same plane to form a filter membrane.
[0044] Further, the seven shark-scale shield micro-blades 1 in the hexagonal shield group 2 are gradually reduced in height from the middle to both sides.
[0045] Further, the material of the filter membrane includes polyacrylonitrile, polyethersulfone, polyvinylidene fluoride and polystyrene.

Abstract
A shark-scale shield micro-blade filter membrane of the present invention relates to a filter membrane with a micro-blade structure obtained through a bionic shark-scale shield, the purpose of which is to overcome the need for post-processing after pollution of the existing filter membrane and reduce the use of the filter membrane The problem of lifespan includes multiple shark-scale shield micro-blades; adjacent shark-scale shield micro-blades are connected by connecting ribs, and multiple shark-scale shield micro-blades are arranged parallel to each other along the same plane to form a filter membrane; and adjacent There are gaps between the micro-blades of the shark-scale shield; the middle part of the micro-blade of the shark-scale shield is a triangular prism, and the back is raised as a blade; the front end of the micro-blade of the shark-scale shield is a tip; the rear end of the micro-blade of the shark-scale shield is concave to form a gap, forming a swallowtail shape.
Description
A Shark Scale Shield Microblade Filter Membrane technical field The present invention relates to a kind of filtration membrane, be specifically related to a kind of filtration that obtains with micro-blade structure by bionic shark scale shield membrane. Background technique Traditional filtration membranes are widely used in water purification and sewage treatment industries, and have made great contributions. The serious membrane fouling problem has become a bottleneck that inhibits the development of filtration membrane technology in the water treatment industry. The main constraints are During the treatment process of the filtration membrane, a large number of pollutants such as microorganisms are trapped on the membrane surface and in the membrane pores, causing the membrane surface to be ineffective. Reversible adsorption and blockage greatly reduce the membrane flux and membrane rejection rate, and the reduced membrane flux cannot be recovered, that is, the f...
