NOVELTY - Use of microbial composition for processing fecal sewage, which involves incubating fecal sewage under anaerobic condition, stacking fermenting materials into bottom layer, middle layer and top layer, spraying microbial composition on stacked layers, incubating mixture, mixing Aspergillus oryzae, Saccharomyces cerevisiae and Bacillus subtilis, mixing pretreated fecal sewage, agricultural waste, fermented mixture and microbial liquid, fermenting mixture, crushing fermented product and granulating crushed product to obtain organic fertilizer.    USE - The microbial composition is useful for processing fecal sewage which is used for obtaining an organic fertilizer (claimed).    ADVANTAGE - The microbial composition enables effective treatment of the fecal sewage, and hence prevents environmental pollution. The processing method saves energy as fermented product is allowed to dry naturally without requirement of additional energy source.    DETAILED DESCRIPTION - Use of microbial composition for processing fecal sewage, which involves (a) incubating the fecal sewage under anaerobic condition for 24-48 hours to obtain pretreated fecal sewage, (b) stacking fermenting materials into bottom layer up to a thickness of 100-160 cm, middle layer and top layer up to a thickness of 8-20 cm, spraying microbial composition on the stacked layers at a rate of 0.5-2 kg/m2, mixing the microbial composition inoculum with the stacked material in a mass ratio of 3-6:1, again spraying the microbial composition at a rate of 0.3-1 kg/m2, incubating the mixture for 60-90 hours to obtain fermented mixture, mixing Aspergillus oryzae, Saccharomyces cerevisiae and Bacillus subtilis to obtain microbial liquid such that concentration of each microorganism reaches more than 10 hundred million colony-forming units (cfu), density reaches 0.096-0.16 g/cm3 and water absorption rate reaches 15-60%, and obtaining agricultural waste containing cellulose, starch and protein and having litter density of 0.2-0.4 g/cm3, water absorption rate of 15-65% and total density of 0.45-0.55 g/cm3, and (c) mixing the pretreated fecal sewage, fermented mixture, agricultural waste and microbial liquid in a volume ratio of 1:45-55, fermenting mixture for 30-100 days, crushing fermented product, and granulating crushed product to obtain organic fertilizer.
