Abstract
A catalyst for the treatment of a waste water comprises an oxide and/or a composite oxide of manganese, the oxide and/or the composite oxide of at least one metal selected from the group consisting of iron, titanium, and zirconium, and optionally a precious metal. A method for the production of this catalyst is also disclosed. A method for the treatment of a waste water comprises subjecting the waste water to wet oxidation treatment with an oxygen-containing gas by the use of a catalyst under pressure such that the waste water retains the liquid phase thereof.
