NOVELTY - Composting organic waste, comprises (a) introducing organic waste and aerobic fermentation microorganism culture into a sealed high-temperature aerobic fermenter (1), supplying pure oxygen or oxygen enriched in pressure swing absorption process, and performing high-temperature aerobic fermentation at 50-70 degrees C, (b) introducing aerobic fermented product and moisture adjusting agent into a blender, and mixing, (c) introducing the mixture into a secondary fermentation and aging tank, flipping with a rotary mixer (9) or shovel car (10), and performing secondary fermentation and aging.    USE - The method is useful for composting organic waste (claimed).    ADVANTAGE - The method composts organic waste in cost-efficient manner, and reduces odor of the compost.    DETAILED DESCRIPTION - Composting organic waste, comprises (a) introducing organic waste and aerobic fermentation microorganism culture into a sealed high-temperature aerobic fermenter (1), supplying pure oxygen or oxygen enriched in pressure swing absorption process, and performing high-temperature aerobic fermentation at 50-70 degrees C, (b) introducing aerobic fermented product and moisture adjusting agent into a blender, and mixing, (c) introducing the mixture into a secondary fermentation and aging tank, flipping with a rotary mixer (9) or shovel car (10), and performing secondary fermentation and aging, or (d) introducing organic waste and moisture adjusting agent into a blender, and mixing, (e) introducing the obtained mixture and aerobic fermentation microorganism culture into the sealed high-temperature aerobic fermenter, supplying pure oxygen or oxygen enriched in pressure swing absorption process, and performing high-temperature aerobic fermentation at 50-70 degrees C, and (c). The organic waste includes food waste, livestock manure, human waste, waste molasses, alcohol waste, waste discharged from slaughterhouse, waste discharged from food processing plants, excess sludge discharged from wastewater treatment plants or waste discharged from agricultural and aquatic processing.
