NOVELTY - Domestic animals excrement disposal system comprises a fecal treatment main body (100) equipped with a space having an inlet and an outlet, a stirring blade, and a ventilation machine; a steam generator (200) for spraying steam through multiple nozzles to the space; a microorganism feeder (400); an air supply unit (500) for supplying air within the space; a cooling water supply unit (300) for lowering temperature of the space; a temperature and humidity sensor for sensing temperature and humidity of the space; and a control unit for automatically controlling each part through sensing valves.    USE - The device/the method is useful for processing cattle excrement.    ADVANTAGE - The device/the method minimizes harmful ingredients by fermentation and drying.    DETAILED DESCRIPTION - Domestic animals excrement disposal system comprises a fecal treatment main body (100) equipped with a space having an inlet and an outlet for accommodating animal excrement, a stirring blade for stirring the animal excrement put in the space through the rotation of a rotating shaft, and a ventilation machine for discharging gas; a steam generator (200) for spraying steam through multiple nozzles to the space; a microorganism feeder (400) for injecting liquid microorganisms to the space through multiple nozzles; an air supply unit (500) for supplying air within the space; a cooling water supply unit (300) for lowering temperature of the space by cooling the fecal treatment main body by cooling water; a temperature and humidity sensor for sensing temperature and humidity of the space; and a control unit for automatically controlling the each part through sensing valves. An INDEPENDENT CLAIM is also included for processing domestic animals excrement comprising inputting animal excrement into the space through the inlet of the fecal treatment main body, sterilizing by supplying steam through a steam supply unit within the space, supplying cooling water to the main body, adding the liquid microorganism for fermenting the sterilized and cooled excrement within the space through the feeder at 35-37 degrees C by supplying steam, drying the fermented excrement by supplying air, and discharging the dried and processed excrement through the outlet.
