Abstract
PURPOSE: To reduce COD of waste water contg. PVA to lower than a normal value, by bringing the waste water contg. PVA into contact with oxygen or an oxygen-generating substance in the presence of Raney copper catalyst to oxidize and decompose PVA.
CONSTITUTION: An alloy of Cu with Mg, Al, Zn or the like is reacted with an aqueous alkali or acid solution to prepare Raney copper catalyst. The catalyst is brought into contact with waste water contg. PVA in a reaction vessel, and one or more selected from pure oxygen, air, oxygen-contg. gas, hydrogen peroxide and the like is added to the water to carry out the reaction. Thus, PVA in the waste water is decomposed, its COD is reduced to a value lower than a normal value, and the treated water can be drained to outside.
