dc.description.abstractProvided is a methane fermentation treatment method which is capable of subjecting an organic waste having a low nitrogen concentration to a methane fermentation treatment efficiently. The methane fermentation treatment method includes: supplying an organic waste to a methane fermentation tank to perform a methane fermentation treatment, the organic waste having a ratio of a chemical oxygen demand concentration to a nitrogen concentration (COD/N ratio) of 50 or more; taking out a fermentation liquid from the methane fermentation tank by predetermined amounts; separating the fermentation liquid into a separated sludge and a separated liquid; and returning at least a part of the separated sludge to the methane fermentation tank, characterized in that the method includes: measuring directly or indirectly a concentration of ammonia nitrogen in the fermentation liquid in the methane fermentation tank; and controlling an amount of the separated sludge returned to the methane fermentation tank so that the concentration of the ammonia nitrogen exceeds a predetermined value.id
