The invention belongs to the field of garbage treatment, and especially relates to a food waste treatment system. Aiming at the existing sewage in garbage, sewage is purified by adopting a mode of manually putting activated carbon for adsorption, the method is time-consuming and labor-consuming, delivery efficiency, slow sewage purification, the use requirements cannot be met. Proposed now is thefollowing scheme, the system comprises a treatment box of a hollow structure, a rotating hole, a rotating groove, a rotating column, stirring blades, an L-shaped plate, a motor, a feeding box, a rectangular plate, a limiting groove, a mounting hole, a mounting rod, a cam, a chute and a sliding block. The food waste treatment system has the advantages that the sewage treatment device is simple in structure and convenient to operate, activated carbon can be quickly and conveniently fed into sewage in the treatment box, the sewage and the activated carbon can be uniformly stirred, the purification efficiency can be improved, and the automation can be realized.
