The invention discloses a green, efficient, convenient, fast and movable kitchen waste fermentation treatment system. The system is characterized in that kitchen waste is conveyed to a smashing devicethrough a kitchen waste conveying device, the kitchen waste is separated into solid-state substances and oil-water mixtures through a solid-liquid separation device, the solid-state substances are fermented and converted into an organic fertilizer through a kitchen waste biochemical degradation device, and the oil-water mixtures are decomposed into grease and reclaimed water through an oil-waterseparation device. According to the system, the equipment is moved to scattered users to enable the kitchen waste to be converted into the organic fertilizer, grease and reclaimed water resources, sothat recycling, harmlessness and reduction of the kitchen waste are realized.
