Organic and inorganic compound fertilizer prepared from kitchen waste, and preparation method of organic and inorganic compound fertilizer

The invention relates to organic and inorganic compound fertilizer prepared from kitchen waste, and a preparation method of the organic and inorganic compound fertilizer. The kitchen waste is not general perishable organic waste. The basic component of the kitchen waste is water; the water causes the kitchen waste to consume a great deal of regulators during corruption, and the physical propertiesof the product are poor, so that dehydration becomes a necessary link for the harmlessness and resource utilization of fertilizer production. In a process of preparing the organic and inorganic compound fertilizers by using the kitchen waste, concentrated sulfuric acid, fertilizer grade ammonium hydrogen phosphate, ammonium sulfate and potassium urea sulfate are successively added, and sterilization, deodorization, conversion and compounding are carried out; the reaction heat in a granulation process enables a large amount of water in the kitchen waste to be evaporated or converted into crystal water, so that harmles
