The invention provides a method for preparing biomass fuel by using cephalosporin residues, and relates to the technical field of biofuel. The method comprises the following steps: carrying out high-pressure plate frame filtration treatment to obtain filter residues with the halogen content of less than or equal to 0.3% and the alkali metal content of less than or equal to 0.4%, and drying the filter residues until the water content is lower than 25% to obtain the biomass fuel. The biomass fuel has a very high heat value and good combustion performance; meanwhile, the biomass fuel is high in calcium content, can play a role in sulfur fixation under the condition that a sulfur fixation agent is not added, and is beneficial to reducing the desulfurization load of combustion tail gas; moreover, the biomass fuel is low in halogen content and alkali metal content and small in damage to equipment during combustion, and the problem that the combustion equipment is corroded when the cephalosporin residues are combust
