Abstract
PURPOSE: To alleviate the load and to miniaturize the equipment, by subjecting a liquid desulfurization waste to wet oxidation treatment to precipitate formed ammonium sulfate and then to an active sludge process.
CONSTITUTION: A liquid waste from wet desulfurization of coke oven gas is subjected to wet oxidation treatment so as to selectively oxidize and decompose ammonium thiosulfate in a weakly acid or alkaline pH range at a temperature lower than 200°C. Thereafter, formed ammonium sulfate is precipitated and separated, and the treated waste water is purified in an active sludge process. That is, the active sludge-process is carried out after precipitation and separation of ammonium sulfate. Consequently, the load for that part can be alleviated.
