摘　　要：介绍了浙江省某集团化纤有限公司油剂废水预处理工程的设计、调试及运行结果。采用隔油+Fenton氧化+混凝沉淀工艺处理高浓度纺丝油剂废水(COD<30g/L),COD去除率达到了70%以上,油去除率达到了83%。工程实践表明,该预处理工艺能够有效地破乳、沉淀去除该废水中的油污和有机物;当操作参数控制适宜时,处理效率稳定。The process design, debugging and operation effect of spinning oil wastewater pretreatment project in a chemical fiber company are introduced. The combined process, separation＋Fenton oxidation＋coagulation precipitation,has been used for treating the spinning oil wastewater whose COD is lower than 30 g/L. Its COD removing rate reaches 70% and oil removal rate 83%. The engineering practice shows that this pretreatment process could efficiently remove COD and oil from the spinning wastewater by demulsification and coagulation precipitation. The treatment efficiency is stable, when the operation parameters are controlled suitably.
