The invention provides a comprehensive processing technology of organic wastes, belonging to the technical field of environmental protection, and in particular relates to resourcing comprehensive processing technology of organic wastes. The invention comprises the following steps: a. preparing materials: placing liquid or solid organic wastes into different storing tanks; b. pretreating: crashingthe organic wastes to particles with the granuality of being equal to or less than 30 mm, conveying the well-crashed materials into a stackretting tank for stackretting; c. mixing and matching various organic wastes and process water, wherein, the carbon nitrogen ratio (C/N) of the materials is 20-30:1, and the concentration of TS is 30%-35%; d. adding the inoculum, adopting high temperature dry anaerobic fermentation to carry out anaerobic fermentation on pretreated materials; and e. manufacturing from the biogas residues generated in step d into efficient multifungus composite ecological organic fertilizer, backflowing the generated biogas liquid to adjust the state of the anaerobic fermentation system or ensure the biogas liquid to enter the aerobic composting process flow, and introducing the generated biogas to a thermoelectricity cogeneration unit to provide electrical energy and thermal energy required by the process system. In the invention, composite microorganism agent and biogas residues and other base stocks are adopted for composite preparation, thus greatly improving fertilizer efficiency, lowering cost, having effects of diversification of nutrients, stable fertilizer efficiency and non pollution, and being suitable for being applied for various crops.
