NOVELTY - Treating kitchen waste resource comprises (i) performing solid-liquid separation to the collected kitchen wastes, (ii) performing hydraulic pulping to the crushed kitchen wastes, (iii) feeding the base materials into a hydrolytic acidification tank for performing anaerobic fermentation, (iv) dehydrating the biogas residues after anaerobic fermentation, placing the biogas residues into a fertilizer making system, adding required nutritional elements according to ingredients of the materials, and regulating the quality of the organic fertilizer, and (v) recycling the oil in the wastewater.    USE - The method is useful for treating kitchen waste resource.    ADVANTAGE - The method: recycles the kitchen waste resources; turns the kitchen wastes into wealth; and is environmental friendly.    DETAILED DESCRIPTION - Treating kitchen waste resource comprises (i) performing solid-liquid separation to the collected kitchen wastes, dividing the materials into solid and liquid parts, sorting the solid part, then extruding and dehydrating the solid part for further solid-liquid separation, placing the solid part into a crushing and sorting device, crushing the large materials to have a particle size of less than 50 mm, and placing the solid-liquid separated liquid part into an oil-water separation system, (ii) performing hydraulic pulping to the crushed kitchen wastes, preparing the materials into uniform slurry having a solid rate of 5-15% and having a solid particle size of less than 10 mm by a hydraulic shear knife, and sorting out the impurities to obtain the base materials, (iii) feeding the base materials into a hydrolytic acidification tank for performing anaerobic fermentation, and converting the organic substances in the materials into biogas, (iv) dehydrating the biogas residues after anaerobic fermentation, placing the biogas residues into a fertilizer making system, adding required nutritional elements according to ingredients of the materials, regulating the quality of the organic fertilizer, and granulating, molding and drying the organic fertilizer to obtain the final products of the organic fertilizer, and (v) recycling the oil in the wastewater by oil-water separation, and using the recycled oil as the industrial raw materials.
