Method for bio-organic dry treatment and recovery of kitchen wastes

The invention discloses a method for bio-organic dry treatment and recovery of kitchen wastes. The method includes steps: (1) preparation of straw cakes serving as kitchen waste carriers; (2) centralized recovery of the kitchen wastes; (3) anaerobe digestive treatment of the kitchen wastes, to be more specific, inputting pretreated kitchen wastes and straws into a high-temperature biogas digester, and sealing the digester to allow anaerobe fermentation in the digester to decompose and transform organics in the kitchen wastes into biogas and water, wherein only a small part of difficult-to-decompose substances and newly generated microorganisms are remained in a form of digested sludge to produce organic biogas residue fertilizers. The method has advantages that recycling in a whole process is realized, generation of waste water and waste gas is avoided, and zero emission is realized; biological digestive treatment in the whole process is harmless and free of transformation pollution, and waste recycling is re
