▎ 摘　　要

NOVELTY - The method comprises (1) mixing graphene and polyacrylonitrile and performing electrospinning to obtain graphene-polyacrylonitrile nanofibers, (2) weaving the graphene-polyacrylonitrile nanofiber and the plant fiber to obtain the graphene-polyacrylonitrile-plant fiber film, (3) subjecting the graphene-polyacrylonitrile-plant fiber film to hydrothermal carbonization treatment to obtain graphene-polyacrylonitrile nanofiber-carbon composite material, and (4) adding graphene-polyacrylonitrile nanofiber-carbon composite material to the microbial suspension, and carrying out the enrichment culture of microorganisms to obtain a microbial-loaded nanomaterial film. USE - Method for preparing nanomaterial film loaded with microorganisms, which is used in sewage deodorizing device used for deodorization of sewage. ADVANTAGE - The nanomaterial film is convenient for attachment of microorganism, and has high chemical resistance, heat stability and wettability, and improved efficiency and effect of deodorization of sewage. The method has simple preparation technique, relatively low energy consumption, and lower cost of graphene, and can treat heavy metal, dye, small molecular organic matter and other pollutants. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a nano-material film loaded with microorganisms; and a sewage deodorizing device containing the nanomaterial film loaded with microorganism. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an internal structure of a sewage deodorization device. 1Deodorization box 2Adjacent nano-material films 3Water outlet pipe 4Limiting plate 5Rotating rod 6Diameter-changing spiral conveying mechanism 7Second microorganism film 8Driving wheel 9Driven wheel 10Circulating pipe 11Circulating pump 12Solid-liquid separating box 13Filter plate 14Inclined plate 15Connecting pipe 16Sewage inlet 17Garbage receiving box 18Motor
