摘　　要：分析评价催化臭氧氧化技术在污水三级(深度)处理领域的应用效果,对炼化企业污水提质技术的选择具有重要意义。对工业化运行的含油污水和含盐污水两套典型的非均相催化臭氧氧化装置进行现场调查、运行水质数据收集和取样分析,装置的进出水化学需氧量(COD)统计和分析结果表明:非均相催化臭氧氧化对含油污水和含盐污水COD具有一定的去除作用,但催化剂失活较快;运行一段时间后COD平均降低约10 mg L,与无催化的臭氧氧化效果相当,对改善生化需氧量(BOD)基本无效。Analysis and evaluation of catalytic ozonation technology in the third-stage(deep)treatment of wastewater is of great significance to the selection of wastewater quality improvement technology in refining and chemical enterprises.Through on-site investigation,operational water quality data collection and sampling analysis of two typical heterogeneous catalytic ozonation units for oily and saline wastewater in industrial operation,the results of statistics and analysis of chemical oxygen demand(COD)in inlet and outlet water showed that the catalytic ozonation had a certain effect on the removal of COD in oily and saline wastewater,but the deactivation of the catalyst was faster.After a period of operation,the average removal concentration of COD was only about 10 mg L,which was similar to that of non-catalytic ozonation and had little effect on improving biological oxygen demand(BOD).
