The invention discloses an iron-carbon material capable of recycling residual asphalt and a preparation method and application of the iron-carbon material, and relates to the technical field of sewage treatment.The preparation method comprises the steps that scrap iron, carbon powder and the residual asphalt are smashed; mixing the crushed scrap iron, carbon powder and residual asphalt according to different proportions, and then putting the mixture into a ball mill for ball milling to homogenize the mixture; respectively putting the obtained mixtures into a pelletizer for pelletizing, and slowly dropwise adding a medium which enables the mixtures to be agglomerated into balls in the pelletizing process; respectively putting the obtained spherical mixture into an oven for baking and shaping; and putting the obtained spherical mixture into a carbonization chamber for carbonization to obtain the iron-carbon material. According to the preparation method and application of the iron-carbon material capable of recy
