摘　　要：丙烯腈废水中含有大量难降解聚合物,具有一定的生物毒性,增加了废水的处理难度。本文着重介绍了臭氧催化氧化工艺在中石油大庆炼化公司丙烯腈废水深度处理中的工程应用情况。在系统运行初期,处理效果良好,出水COD去除率可达54%。但由于系统长期处于高负荷连续运行状态,使得部分催化剂板结失活,致使设备处理效率下降,COD平均去除率仅为16%。在装置进行定期反洗后,COD去除率平均为50%。There are a lot of non-biodegradable and biotoxic organics in the acrylonitrile wastewater,increasing the difficulty of wastewater treatment. It was focused on the application of ozone catalytic oxidation process in advanced treatment of acrylonitrile wastewater in Oil Refinery Chemical Co.,Daqing CNPC. At the beginning,the result was good with an effluent COD removal rate of 54%. However,due to the long-term continuous operation under the high loads,catalyst deactivating occurred,leading to a decreased COD removed rate of 16%. Finally,COD removal rate could achieve50% with a periodic backwashing.
