The invention relates to a device for removing ammonia nitrogen from mine water, and belongs to the technical field of sewage treatment devices. The device mainly overcomes the defects of high operation cost and difficult control of the residual chlorine index of effluent of a traditional technology for removing ammonia nitrogen from mine water by a breakpoint chlorination process. The device forremoving ammonia nitrogen from mine water comprises an anticorrosion box body, a water inlet pipe, a water outlet pipe, a backwashing water inlet pipe, a backwashing water outlet pipe, a backwashing air inlet pipe, a water discharge pipe, a backwashing fan, an aeration fan and a backwashing water pump; and a cavity is formed in the bottom of the inner cavity of the anticorrosion box body, a plurality of long-handle filter heads are arranged above the cavity, a supporting layer, a zeolite filter material layer and an activated carbon filter material layer are sequentially arranged above the long-handle filter heads in
