<P>PROBLEM TO BE SOLVED: To provide a treatment method and a system for organic waste where, in treatment for organic waste provided with a methane fermenter, soluble sludge can be removed without causing the reduction of pH, and further, the miniaturization of apparatus is made possible. <P>SOLUTION: In the treatment system for organic waste provided with: a regulation tank 11 for performing the acid production reaction or solubilization of organic waste; a methane fermenter 12 for performing the methane production reaction of the organic waste whose molecules are made low in the regulation tank; and activated sludge treatment equipment 13 for subjecting the treated liquid exhausted from the methane fermenter to activated sludge treatment, an iron electrolytic cell 17 into which the organic waste drawn out from the regulation tank 11 is introduced is provided, iron ions are eluted by electrolytic reaction in the electrolytic cell 17, the iron electrolytic solution containing the iron ions is returned to the regulation tank 11, and soluble sludge such as phosphorous and COD (Chemical Oxygen Demand) contained in the organic waste is subjected to flocculation separation by the iron ion. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
