Harmless alkalization treatment method of organic waste

The invention provides a harmless alkalization treatment method of organic waste, which is characterized by comprising the following steps: 1) uniformly mixing CaO and organic waste according to a mass ratio of (1-2): 1, and standing for 48-72 hours to obtain a mixture; (2) crushing the mixture to 5-50mm, screening, separating out organic wastes and Ca (OH) 2, spreading and airing the separated organic wastes for 2-7 days to obtain an air-dried substance, calcining the separated Ca (OH) 2 in a kiln to generate CaO, and returning to the step (1) to participate in mixing; and 3) burning the air-dried material at 1000-1400 DEG C, or directly using the air-dried material as an organic fertilizer. The solid state of the easily-decayed organic waste is kept from the source, toxic and harmful waste water and waste gas generated by the organic waste are completely eradicated, the hidden danger of secondary environmental pollution is eliminated, the process is simple, efficient, high in operability, small in equipment
