METHOD FOR PROCESSING WASTE WATER CONTAINING POLYETHER POLYOL |
摘要 |
A method of treating wastewater containing water-insoluble high molecular weight polyether polyol impurities comprises reacting the aqueous waste stream with an oxidizing agent and optionally with a transition metal catalyst. The molecular weight of the polyol impurities is reduced to less than about 1,000, thereby improving the biodegradability of the stream. |
