PROBLEM TO BE SOLVED: To provide a fermentation apparatus which prevents intrusion of bacteria into an anaerobic fermentation tank, and allows to have a temperature suitable to hydrogen fermentation and methane fermentation. SOLUTION: This fermentation tank 1 comprises: a pretreatment apparatus 2 for pretreatment of organic waste; a hydrogen generation device 3 forming hydrogen by hydrogen forming bacteria; a methane generation device 4 forming methane by methane forming bacteria; a sterilizing means 100, 200, 300; and a waste water treatment device 6. The sterilizing means 100, 200, 300 perform heating sterilization and cooling of the organic waste. COPYRIGHT: (C)2005,JPO&NCIPI
