[0027] The present embodiment also provides a process based on the above-mentioned three-phase synchronous treatment system for garbage, which includes the following steps: (1) collecting various types of garbage by a sanitation vehicle and pouring them into a garbage storage tank 100; (2) conveying the garbage in the garbage storage tank 100 and the garbage liquid in the garbage liquid collection tank 12 to the feed hopper of the shaftless screw feeder 31 by the garbage transport device 200 and the first screw pump 13; (3) conveying the garbage and the garbage liquid to the ball mill 32 by the shaftless screw of the shaftless screw feeder 31; (4) The steel balls repeatedly throw and grind the garbage and garbage slurry to form garbage fragments, garbage fine powder or garbage fine slurry.

[0028] As a further improvement of the present invention, in step (4), after the garbage and garbage slurry are repeatedly thrown, smashed and ground by the steel balls of the ball mill 32, combustible materials such as plastics, bamboo, wood and fabrics are turned into fragments, inorganic materials such as metals, glass, ceramics, stones, bones and shells are turned into garbage fine powder, and kitchen waste is turned into garbage fine slurry. At the same time, the inorganic materials play a grinding role, grinding waste with waste. During the grinding process, the ball mill 32 is free of entanglement and jamming, which is energy-saving and environmentally friendly. The garbage fragments, garbage fine powder or garbage fine slurry will undergo Fenton-like reactions, electrochemical reactions, mechanochemical reactions and aeration reactions with scrap iron, carbon and various active substances in the ball mill 32, which can quickly decompose pollutants and greatly reduce the burden of garbage liquid and odor treatment.
