<p>PROBLEM TO BE SOLVED: To provide a methane fermentation treatment apparatus for realizing methane fermentation at a low cost by placing an interest in the fact that a methane fermentation treatment apparatus employing a UASB(upflow anaerobic sludge blanket) method is high in cost because it is a tower type and converting this treatment apparatus to a horizontal type one. SOLUTION: A bag 3 is floated in an anaerobic tank 1 and a pretreated liquid containing an organic acid is allowed to flow in the bag 3 from one end thereof to perform methane fermentation in the bag 3. Treated water subjected to methane fermentation treatment is discharged from the other end of the bag 3 and the methane gas formed in the bag 3 is taken out of the bag 3.</p> |
