表面活性剂吸收法治理含苯废气的中试实验_衣新宇表面活性剂吸收法治理含苯废气的中试实验衣新宇,赵修华,朱登磊(同济大学污染控制与资源化研究国家重点实验室,上海200092)摘要:采用添加表面活性剂的填料塔来吸收治理含苯废气,分析了水-吸收剂的吸收机理。考察了喷淋量、废气入口浓度和表面活性剂添加量这三个因素对苯去除率的影响。结果表明,对苯来说入口浓度对去除率的影响最大,喷淋液体流量次之,表面活性剂的影响最小。条件满足时,含苯废气可以达标排放。关键词:表面活性剂;吸收法;苯;中试中图分类号:TQ123文献标识码:A文章编号:1006-8759(2004)03-0024-04THEMIDDLETESTONTREATINGBENZENEEXHAUSTBYPACKINGSCRUBBERADDEDSURFACTANTYIXin-yu,ZHAOXiu-hua,ZHUDeng-lei(NationalKeyLabonPollutionControl&ResourceResearch,TongjiUniversity,Shanghai200092,China)Abstract:Treatingbenzeneexhaustbypackingscrubberthataddedsurfactants,andanalyzingthewater-additiveabsorptionmechanism.Forthecomplicationoftheexperiment,theoutcomesareanalyzedbyplaning.Throughthecomparisonofthreekindsoffactors(sprayflow、inletconcentra-tion、surfactantadditive)byplanning,wegetthefollowingconclusion:forremovalrateofbenzene,inletconcentrationhasthemaximumeffect,waterflowasthefollowing,andsurfactantshavetheleast.Whentheconditionisfulfilled,thebenzeneexhaustcanbedischargedinproperstandard.Keywords:surfactant
