<P>PROBLEM TO BE SOLVED: To provide an organic wastewater treatment apparatus and treatment method, capable of facilitating treatment of methane generated during methane fermentation treatment and dissolved in methane fermentation treatment water without diffusing the methane to the atmosphere. <P>SOLUTION: The organic wastewater treatment apparatus 101 includes a methane fermentation treatment tank 10 for performing methane fermentation treatment of organic wastewater; an immersion type reaction tank 20 which is filled with methane fermentation treated water 2 treated in the methane fermentation treatment tank 10 to perform aerobic biological treatment of the methane fermentation treated water 2; and a solid-liquid separator 30 which separates solid from liquid, the solid and liquid being contained in mixture 3 stored in the reaction tank 20. The methane fermentation treatment tank 10 includes a lid section for preventing the methane dissolved in the methane fermentation treated water 2 stored in the methane fermentation treatment tank 10 from diffusing to the atmosphere and a supply section 13 for supplying the methane fermentation treated water 2 to the reaction tank 20 while keeping the state where the dissolved methane is prevented from diffusing to the atmosphere. <P>COPYRIGHT: (C)2012,JPO&INPIT |
