摘要： A process for treating waste water from an industrial process for producing propylene oxide, which process involves the steps of: (a) subjecting the waste water to a multi-effect evaporation treatment resulting in a vaporous top fraction and a liquid bottom fraction containing the non-volatile contaminants; and (b) condensing at least part of the vaporous top fraction into a liquid stream which is subject to a stripping treatment resulting in an overhead stream containing volatile waste organic material and purified water as the liquid bottom stream.
