Problems solved by technology

[0004] In order to solve the problem that on the one hand, activated carbon is generally prepared by wood and bamboo, which leads to high cost and is not conducive to the sustainable development of the ecological environment; on the other hand, the service life of activated carbon is short, which easily causes secondary pollution of the indoor environment; and the use of metal oxides Modification of activated carbon can improve the service life of activated carbon and the performance of formaldehyde degradation, but it will lead to the problem of increased preparation cost

Abstract

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.

Description

technical field [0001] The invention belongs to the field of solid waste resource utilization, and specifically relates to a method of grinding biomass waste and Bayer process red mud, and using Bayer process red mud powder to modify the biomass waste micropowder to obtain Bayer process red mud modification. Biomass activated carbon. Background technique [0002] About 80% of people's life is spent indoors, so the indoor environment is the place where people are most frequently in contact with, and the quality of the air quality will directly affect the health of the people who live there. At present, with people's requirements for building thermal insulation performance and interior decoration beautification, the concentration of volatile organic compounds in the indoor environment has increased, leading to increasingly serious problems with indoor air quality. The focus of quality. [0003] Activated carbon is a carbonaceous material with developed porous structure and r...
