<p>PROBLEM TO BE SOLVED: To provide device of treating organic waste which enables almost completely extinguishing various organic waste such as garbage which is discharged from general home, restaurant and food factory, etc., and sludge which is discharged from waste water treatment plant of the food factory, etc., and extremely reducing biochemical oxygen demand(BOD), chemical oxygen demand(COD) and SS(solid content, suspended matter). SOLUTION: Porous micro-organism treatment medium and treatment water are supplied into an extinguishing vessel, at the same time, the organic waste is charged, is heated to the optimum temperature of middle or high thermophilic bacterial and is aerated while being stirred with a stirrer, and, thereby, the aerobic fermentation and the facultative anaerobic fermentation are performed. The treatment water which contains the organic material decomposed in the extinguishing vessel is aerated in an aeration treatment vessel and, thereby, the aerobic fermentation and the facultative anaerobic fermentation are performed. The treatment water which contains the organic material treated in the aeration treatment vessel is separated by sedimentation into precipitated solid contents and unprecipitated solid content containing liquid in a sedimentation treatment vessel. The unprecipitated solid content containing liquid which is separated by sedimentation and treated in the sedimentation treatment vessel is subjected to the aerobic fermentation and the anaerobic fermentation treatment in a final reaction vessel in which the porous micro-organism treatment medium is spread all over the bottom part.</p> |
