NOVELTY - Method for rapidly processing organic solid waste, involves controlling carbon-to-nitrogen ratio of the organic solid waste at 15-35, regulating concentration of nutritional components in the organic solid waste to 5.5-6.5%, adding fermentation strain, carrying out fermentation, adding heat-resistant enzyme and thermophilic strain, carrying out enzymatic fermentation, drying obtained product, cooling dried product to 30-35 degrees C, spraying microbial agent on the product, continuously cooling the product, and sieving obtained product.    USE - The method is useful for rapidly processing organic solid waste (claimed).    ADVANTAGE - The method is suitable for industrial production, consumes less energy, accelerates water loss of the organic solid waste, and simply and cost-effectively processes organic solid waste having good stability.    DETAILED DESCRIPTION - Method for rapidly processing organic solid waste, involves (a) controlling carbon-to-nitrogen ratio of the organic solid waste at 15-35, regulating concentration of nutritional components in the organic solid waste to 5.5-6.5%, adding fermentation strain to the organic solid waste in greenhouse, controlling water content of obtained mixture at 45-55%, and carrying out fermentation to obtain semi-finished product, (b) adding the semi-finished product to reactor, stirring and mixing the semi-finished product for 5-10 minutes, adding heat-resistant enzyme and thermophilic strain, and carrying out enzymatic fermentation at 75-95 degrees C for 5-8 hours under stirring condition, where humidity of mixture is controlled at 60-70% during enzymatic fermentation, air inlet quantity is regulated at 100-900 m3/hour/ton of mixture, air inlet time is controlled for 5-8 hours, and the stirring speed is maintained at 1-20 revolutions/minute (rpm), (c) drying product obtained in step (b), (d) cooling dried product to 30-35 degrees C, spraying microbial agent on the product, and continuously cooling the product, and (e) sieving obtained product.
