The invention discloses an organic waste and animal excrement harmless treatment method. The method includes the first-stage
fermentation step and the second-stage
fermentation step. In the first-stage
fermentation step, materials needing to be treated are continuously overturned and stirred, hot air is injected in the materials, ventilation is kept, and the materials are fermented for 3-7 days at high temperature under the action of high-
oxygen-consumption microorganisms, so that the materials are deodorized and cured, and the
water content is reduced to 35-45%. In the second-stage fermentation step, the materials are kept in the accumulated state for 5-8 days, and ventilation is continuous, so that the materials are fully cured, the
water content is reduced to 20-30%, and the dried cured materials are formed. The aerobic fermentation mechanism of the microorganisms is used, the treated materials are overturned and subjected to
oxygen adding, and ultrahigh temperature aerobic
microorganism development is used, so that the temperature of the materials is over 70 DEG C, the materials can be quickly evaporated, dehydrated and cured, energy in
organic matter is released, and various kinds of
organic matter are oxidized. By means of the method, breeding waste, organic waste of agricultural
product processing enterprises, waste of
slaughter houses, organic waste generated in production,
urban life waste, and farmer courtyard and farmland waste can be treated.
