The invention discloses a garbage treatment box facilitating garbage solid-liquid separation, and belongs to the technical field of garbage treatment boxes. The garbage treatment box comprises a base.A treatment box body is fixedly arranged at the top of the base and comprises a bottom box fixed to the top of the base, and a dewatering and drying part is movably arranged in an inner cavity of a top box. A compression supporting plate mechanism matched with the dewatering and drying part is arranged at the top of an inner cavity of the bottom box, and a cleaning pushing structure matched withthe compression supporting plate mechanism is arranged on the inner wall of the rear side of the bottom box. According to the garbage treatment box, under pressing of a pressing roller, part of liquidin garbage is separated out. Through a driving motor, a rotating wheel, an incomplete tooth section, a rack, a movable column, a stress spring and a rubber corrugated pipe, the pressing roller rollsto achieve uniform compression of the garbage, and residual liquid continues to be compressed out. After compression, through an air blower, a heating element, a telescopic hose, a hollow shell and anozzle, the treatment efficiency and quality are greatly improved, secondary treatment is not needed, and the energy consumption and the cost are reduced.
