低碳环保与节能减排77NO.052023节能ENERGYCONSERVATION含油污水生化出水提标改造试验研究龚小芝（中石化（北京）化工研究院有限公司，北京100013）摘要：某石化厂含油污水经“缺氧/好氧+膜生物反应器工艺”处理后，出水需深度降低化学耗氧量（COD）至40mg/L以下。针对该问题对比研究臭氧氧化与催化臭氧氧化工艺，选择“催化臭氧氧化+曝气生物滤池”组合工艺。通过催化臭氧氧化条件试验，确定最佳工艺条件为臭氧投加浓度40mg/L、反应停留时间160min，并在该条件下进行稳定运行试验。结果显示：“催化臭氧氧化+曝气生物滤池”工艺可使含油污水生化出水COD去除至40mg/L以下，其中催化臭氧氧化技术可去除废水中低分子量有机物，部分大分子量有机物亦可被转化继而彻底矿化，该工艺适宜应用于含油污水生化出水的深度处理。关键词：臭氧氧化；催化臭氧氧化；曝气生物滤池；提标改造；深度处理中图分类号：X742文献标识码：B文章编号：1004-7948（2023）05-0077-04doi：10.3969/j.issn.1004-7948.2023.05.020ExperimentalstudyonupgradingbiochemicaleffluentfromoilywastewaterGONGXiao-zhiAbstract：Aftertheoilywastewaterfromapetrochemicalplantistreatedbythe'anoxic/aerobic+membranebioreactorprocess',theeffluentCODneedstobedeeplyreducedtobelow40mg/L.Inviewofthisproblem,thecombinedprocessof'catalyticozonation+biologicalaeratedfilter'wasselectedthroughthecomparativestudyofozonationandcatalyticozonationprocesses.Throughthetestofcatalyticozonationconditions,theoptimumprocessconditionsweredeterminedastheconcentrationofozonedosing40mg/L,thereactionresidencetime160min,andthestableoperationtestwascarriedoutunderthiscondition.Theresultsshowthatthe'catalyticozonation+biologicalaeratedfilter'processcanremoveCODfromthebiochemicaleffluentofoilysewagetobelow40mg/L,inwhichthecatalyticozonationtechnologycanremovelowmolecularweightorganicsinthewastewater,andsomehighmolecularweightorganicscanalsobeconvertedandthencompletelymineralized,whichissuitablefortheadvancedtreatmentofbiochemicaleffluentofoilysewage.Keywords:ozoneoxidation;catalyticozonation;aeratedbiologicalfilter;upgradingandrenovation;advancedtreatment引言石化行业的生产用水与废水排放量较大，废水普遍含有油、硫、酚...
