<P>PROBLEM TO BE SOLVED: To provide a method for continuously decomposing COD for a long period of time and a COD decomposition catalyst packed tower in which the method is usable. Ž<P>SOLUTION: In the method of decomposing and removing COD by making waste water containing the COD flow into the packed tower including a COD decomposition catalyst layer which is held between an upper dispersion plate and a lower dispersion plate and carries nickel peroxide on an ion exchange membrane, a demister or a filter cloth is installed between the upper dispersion plate and the COD decomposition catalyst layer. A COD decomposition catalyst packed tower for use in the method is also provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
