Abstract

PURPOSE: To enhance a gas-generating efficiency and to reduce an amount of ammoniac nitrogen, by removing a part of the ammoniac nitrogen so that the ratio of carbon to nitrogen in waste material is controlled in a range suitable for anaerobic methane gas-generating fermentation.
CONSTITUTION: Waste material WM to be disposed is reserved in a reservoir 1, adjusted at pH 10 or higher by addition of an alkali from an alkali tank 11, fed to the top part of a dispersing tower 2 by a pump 12, and dispersed from the top part to strip and purge ammoniac nitrogen as ammonia gas. After stripped, the waste material is received in a pH-adjusting vessel 4, neutralized at pH 7W8 or so by addition of an acid, e.g. sulfuric acid or the like, from an acid tank 41, and carried to an anaerobic fermentation vessel 5. Thereafter, the waste material is fermented. The digested liquid is aerated in an aeration vessel 6, and separated into a solid and a liquid in a solid-liquid separation vessel 7. Said ammonia stripping is done preferably under the condition of C:N=10W20:1.
