VERMICOMPOSTING METHOD TREAT SEWAGE SLUDGE BY COMPOUND MICROORGANISM USING WITHOUT PRETREATMENT PROCESS

摘要

A method for vermicomposting sewage sludge is provided to reduce composting term, cost, and space largely, enable stable earthworm treatment, and decrease a bad smell generated during a vermicomposting step. A method for vermicomposting sewage sludge includes the steps of: culturing four kinds of composite strains to x10^8, respectively; mixing the every microorganism in an equal amount to prepare a microorganism culture medium; innoculating 10 L of the culture medium onto 1 ton of sewage sludge and mixing the resultant; and feeding the sewage sludge to earthworms without a separate pretreatment process. Further, the composite strains are Rodobacter capsulata, Bacillus megaterium, Geobacillus stearothermophilus and Rhodococcus sp..
