<p>PROBLEM TO BE SOLVED: To dispose crude sludge, animal feces, etc., especially sludge from municipal wastewater by mixing a specific aerobic bacterium, etc., belonging to Bacillus with crude sludge, etc., during hot, and fermenting the mixture while it is hot under aerobic conditions. SOLUTION: Sludge obtained from municipal wastewater or crude sludge such as animal feces is mixed with at least one kind of aerobic bacterium selected from a group consisting of FERM P-15536, FERM P-15537, FERM P-15538, FERM P-15539, FERM P-15540, FERM P-15541 and FERM P-15542 belonging to Bacillus, a mixture of them or its cultured body while the cultured body is hot, and the resultant mixture is fermented while it is hot under aerobic conditions to convert the crude sludge to an organic fertilizer.</p> |
