Abstract

PURPOSE: To neutralize slaked lime in high alkaline sludge in a preprocess and activate fermenting treatment in an after-process by a method wherein water in carbonic acid gas generated in a fermenting process is removed, and the gas is flowed back, and utilized when fermenting the sludge.
CONSTITUTION: A gas body containing carbonic acid gas, ammonia and water generated from an intermediate stage portion R3, in which fermentation is active, and a lower stage portion Rn is contacted with nater or an acidic solution in a multistage type fermenting tank 1, water is removed by lowering the temperature of the gas body, ammonia is removed by dissolving it in water or reacting it with an acid, the gas body is flowed back into sludge in an upper stage R2, in which fermentation is inactive due to high alkalinity, and alkalinity is neutralized by the carbonic acid gas contained in the gas body.
