Abstract: The invention provides a process for treating waste water from an industrial process for producing propylene oxide, which comprises subjecting the waste water to a catalytic wet oxidation treatment comprising: feeding a stream comprising the waste water to a reactor; subjecting the stream comprising the waste water to an oxidation treatment in the presence of oxygen and a catalyst resulting in a treated stream; sending at least part of the treated stream to a separator wherein the treated stream is separated into a gas stream and a liquid stream; and recycling part of the liquid stream to the reactor.
