description The invention relates to the technical field of sewage treatment, and provides a sulfur-based magnetic filler for sulfur autotrophic denitrification as well as a preparation method and application thereof. The sulfur-based magnetic filler comprises sulfur-containing sludge, biomass, a slow-release inorganic carbon source, an alkaline substance, a metal load, a magnetic material and an adhesive, wherein the sulfur-containing sludge can be obtained from a high-sulfate wastewater anaerobic reactor. The prepared sulfur-based magnetic filler for sulfur autotrophic denitrification can greatly promote the sulfur autotrophic denitrification process of microorganisms, a biological filter is filled with the sulfur-based magnetic filler for sewage denitrification nitrogen removal, and a good nitrogen removal treatment effect can be achieved. According to the invention, high-sulfate wastewater treatment, sludge treatment and sewage sulfur autotrophic denitrification nitrogen removal are coupled. The sulfur-containing slu
