摘　　要：采用生物接触氧化—臭氧氧化—锰砂过滤组合工艺对化工厂二级出水进行深度处理,出水回用于循环冷却水。运行结果表明,处理出水能够满足《城市污水再生利用工业用水水质》(GB/T 19923—2005)中敞开式循环冷却水系统补充水标准要求。该工程运行后,节约了大量新鲜水,减少了COD排放,带来可观的经济效益和环境效益。The combined process of biological contact oxidation-ozonation-manganese sand filtration has been used for advanced treatment of the secondary effluent in a chemical plant. The results show that the treated effluent can meet the requirements of make-up water for the open-type circulating cooling water systems in the Reuse of Urban Recycling Water：Water Quality Standard for Industrial Uses （GB/T 19923--2005）. Since the project began to run, a large quantity of fresh water has been saved, and the discharge amount of COD has decreased, bringing obvious eco- nomic benefit and environmental benefit.
