The invention discloses Bayer-process red mud modified biomass activated carbon for degrading formaldehyde and a preparation method thereof and belongs to the field of resource utilization of solid wastes. The Bayer-process red mud modified biomass activated carbon comprises biomass waste, red mud, phosphoric acid, absolute ethyl alcohol, hydrochloric acid and water. The biomass waste comprises one or more of shells, pits and straws. The red mud is Bayer-process red mud. The Bayer-process red mud modified biomass activated carbon is prepared by compounding the Bayer-process red mud and biomasswaste materials; metal oxide in the Bayer-process red mud is used for carrying out modification treatment on the biomass waste materials and the production cost of the modified activated carbon is reduced by 50 to 60 percent; high-additional-value application of the Bayer-process red mud and the biomass waste materials is expanded and a novel concept of treating dangerous materials with waste isrealized.
