To provide a treatment system suitable for garbage treatment and a garbage treatment equipment for the system.

The garbage treatment system comprises, as its constituent elements, a decomposition vessel provided within it with an agitator; a driving device for the agitator; a dehumidifier, an odor extinction device, an ozone mixer, an ozonizer, and an ozone box, wherein inorganic porous material particles, or in particular, spherical porous casting particles each having a specified diameter are accommodated. This ozone treatment equipment is obtained by connecting these constituent elements of the garbage treatment system to each other with ducts and compactly assembling the elements, wherein each of the two-dot chain lines indicates the gas stream flow and each of the broken lines indicates the water stream flow in Figure 1.
