ABSTRACT:
Waste water containing nitrogen compounds is processed by adding an oxidant to the waste water. The oxidant may be one or more of a chlorine oxidant or hydrogen peroxide. The oxidant breaks down the nitrogen compounds through a breakpoint reaction. The partially processed water then is contacted with a metal peroxide catalyst. The metal peroxide breaks down and removes excess oxidant. The reaction may be carried out at normal temperature and pressure.
