摘　　要：采用非均相催化臭氧氧化工艺(自主研制的铜锰氧化物催化剂)处理炼油废水,探索该工艺深度处理炼油废水的不同影响因素和机制,获得最适宜工艺参数,使处理出水满足炼油企业的回用水标准.考察反应前后催化剂的稳定性.废水取自广东某炼油企业.结果表明:最优值为原始pH=6.8,臭氧投加质量浓度为50mg/L,催化剂质量浓度为3.0g/L.在17℃室温条件下反应15min,出水化学需氧量(COD)满足该炼油企业的回用水标准:COD<50mg/L.氨氮有一定的去除.使用前后,催化剂的抗压性能和活性组分未发生明显变化,催化效果稳定.GC-MS分析结果表明:非均相催化氧化工艺可以减少炼油废水中的大分子有机物质,尤其是含氮的杂环物质,能将高沸点大分子有机物降解为低沸点小分子有机物质,提高炼油废水的可生化性.Heterogeneous catalytic ozonation oxidation was applied for treatment of refinery wastewater wastewater with self-developed copper-manganese oxides（Cu-Mn-O）catalysts.Different influencing factors and mechanism of the advanced treatment were investigated to acquire the optimum technological parameters,so that the treated effluent could meet the refinery＇s standard for reuse water.Moreover,the stability of the catalyst before and after the reaction was studied.The wastewater was obtained from a refinery located in Guangdong province.Results showed that the optimum values were ozone dose 50.0mg/L,catalyst dose 3.0g/L,initial pH =6.8.and at under this condition the effluent＇s chemical oxygen demand（COD）could meet the refinery＇s recycling wastewater standard（COD 〈50mg/L）after reaction for15 min at the room temperature（17℃）.Meanwhile,ammonia nitrogen could be removed to some extent.There was no obvious change of the compressive performance and the active components of the catalysts before and after reaction.Therefore,the catalytic effect was stable.From the GC-MS analysis,heterogeneous catalytic ozonation oxidation can reduce the macromolecular organic matter in wastewater,especially the organic nitrogen compounds.It can also degrade high boiling organic molecules into low boiling small ones,improving the wastewater＇s biodegradability.
