description The invention discloses a method for harmlessly treating electrolytic manganese residues, and relates to the technical field of solid waste treatment and environmental protection application. The manganese slag treatment method comprises the following steps: (1) adding manganese slag and water into a backwashing filter press according to a solid-to-liquid ratio of (1.5-3.5): (0-1), and treating to obtain first treated manganese slag; (2) crushing the first treated manganese slag in a soil crushing machine to obtain a material of which the particle size is less than 2mm, namely secondary treated manganese slag; (3) transferring the secondary treated manganese slag into a double-shaft mixer, synchronously atomizing and spraying an activating agent and spraying a treating agent, stirring and reacting at the temperature of 30-100 DEG C, and absorbing ammonia gas by using an ammonia absorber in the reaction process; and (4) atomizing and spraying a pH back adjusting agent into the material obtained by the reaction
