Abstract: The present application discloses an inorganic-biohybrid and a preparation method and application thereof, and belongs to the technical field of wastewater treatment. The inorganic-biohybrid is obtained by hybridization of multi-walled carbon nanotubes and activated sludge derived from a denitrification biological filter. When being used in a hydrogen-based membrane bioreactor (H2-MBfR) to perform denitrification of wastewater, the inorganic-biohybrid can be attached to a hollow fiber membrane to form a biofilm, so as to increase diffusion rates of H2 and NO3— in the biofilm, thereby effectively alleviating a dual-substrate diffusion limitation of H2-MBfR, increasing an H2 utilization rate thereof and reducing an explosion risk.
