ABR郭满芹 (,136000) [目的]寻找经济、有效的山梨酸废水的处理工艺。[方法]采用ABR高效厌氧反应器,进行山梨酸生产废水的启动试验。[结果]在35℃条件下,经历190d,成功地完成对ABR反应器的启动。进水COD容积负荷由0.26kg/(m3·d)增加到2.16kg/(m3·d),COD去除率达到93%,挥发性脂肪酸(VFA)和pH值也达到要求。在ABR反应器中形成大量性能良好的颗粒污泥,其尺度介于2~5mm。电镜分析表明,不同隔室内呈现种群配合良好的厌氧微生物分布,且各隔室中的颗粒污泥形状各异,表面凸凹不平,存在气孔。第1隔室存在大量优势发酵细菌,沿水流方向颗粒污泥中的微生物逐渐向产甲烷细菌菌群过渡。[结论]好氧处理前先采用厌氧法进行处理,可以完成ABR反应器处理山梨酸生产废水的启动。 ABR反应器;启动;山梨酸废水;颗粒污泥 X703 A 0517-6611(2010)09-04781-03StartExperimentofTreatingSorbicAcidWastewaterwithABRGUOMan-qin (CollegeofEnvironmentalEngineering,JilinNormalUniversity,Siping,Jilin136000)Abstract [Objective]Theresearchaimedtostudyaneconomicandeffectivesorbicacidwastewatertreatmenttechnology.[Method]Thestartingofanaerobicbaffledreactor(ABR)treatingsorbicacidwastewaterwasstudied.[Result]Thereactorwasmaintainedatahydraulicretentiontime(HRT)of24handatemperatureof35℃duringperformancestudystage.Whenthestart-upoftheABRwasfinishedthrough190days,thevolumetricloadingrate(VLR)waschangedfrom0.26to2.16kg/(m3·d).CODremovalefficiencyreached93%withsuit-ablevaluesofvolatilefattyacid(VFA)andpH.Granuleswereexistedinsixcompartmentsattheendoftheexperiment,whosesizewas2-5mm.Themicroscopicanalysisresultsshowedthatcooperativeanaerobicmicrobialpopulationsdistributedwithindifferentcompartments.Thedominantbacteriainthecompartmentonewerefermentativebacteria.Towardstheendofthereactor,thedominantbacterialpopulationsshif-tedstepwisetoMethanogenicbacteriaingranularsludge.Astosinglegranularsludgewithdifferentshape,theairholeswereinitsunevensurface.[Conclusion]Thetreatmentwithanaerobicmethodbeforeaerobicprocesscouldaccomplishthestart-upofanaerobicbaffledreactor(ABR)treatingsorbicacidwastewater.Keywords Anaerobicbaffledreactor;Start-up;Sorbicacidwastewater;Granularsludge 郭满芹(1967-),女,吉林四平人,助理研究员,从事水处理方面的研究。 2009-12-23 。,,。(ABR,Anae-robicBaffledReactor)[1],(UASB,UpflowAn-aerobicSludgeBed)[2],、、、、[3],,[4]。ABR,[5]。,35~40℃,。,,ABR。1 1.1 ABR,、、30、22、50cm,29.7L。4,、,45°,,,1。,RS0082A(50W)35℃。1.2 。COD90g/L,pH3~4,1 ABRFig.1 SketchpictureofABR450NTU。:6.39%、52.36%、2.09%、16.82%、20.22%、2.13%。,BOD/COD≤0.3。BOD5/COD(0.5~0.8)[6],。UASB。,3~5mm,。1.3 ,COD∶N∶P=100∶5∶1,。,Fe、CoNi,COD,[7]。,NaHCO3,pH6.8~7.5。COD900mg/L,pH7.0,0.3m/h。,,ABR1,,JournalofAnhuiAgri.Sci.2010,38(9):4781-4783,4809 刘月娟 卢瑶DOI:10.13989/j.cnki.0517-6611.2010.09.039。ABR,、pH、VFA、COD,、。1.4 《》(3)[8],1。1 Table1 AnalyticalprojectProjectAnalyticalmethodMainInstrumentCODWMXCODpHpHvaluePHS-3CpHVFApH、、MicrobialCharacteristics2 2.1 COD ABR190d。2,COD。7d,,,,30%。,,,。,,,。,,,,。,COD。,COD,COD,;,COD,COD,,。,COD93%,0.26kg/(m3·d)2.16kg/(m3·d)。,,,。2 ABRCODFig.2 RemovalratecurvesofCODatthestart-upstageofABR2.2 pH ,pH,pH5.0~8.5。pH6.5~7.8,pH,pHpH,pHpH[9]。,,pH6.8~7.5,。3,pH6.8~7.5,1、2pH,。1、2,,,,,;,,pH,,。ABR,。4pH。3 ABR60dpHFig.3 ThepHvaluechangecurvesindifferentcompartmentsofanaerobicbaffledreactorbefore160doperating4 pHFig.4 ThepHvalueindifferentcompartmentsafterthetest2.3 VFA 5ABR60dCOD900mg/L1500mg/LVFApH。CODABR,1,VFAs,pH,,VFAs,H2/CO2“”(、、、),pH(6.8~7.2)[10],,VFA,7.8mmol/L。,4782 安徽农业科学 2010,,pH。,VFA。5 VFApHFig.5 RelationshipbetweenVFAofeffluentwaterandpHvalue2.4 ,、。30,3、4。。60,,1,。,。,1,5mm。1234。6,120。,,[11]。ABR,,5000。6,,,,,。1、、,、,、,。2,,,,,。3,,。,:a~d1~4。Note:a-drepresentthegranularsludgefromlstto4thcompartment.6 ABRSEMFig.6 SEMimagesofgranularsludgeafterthestart-upoftheABR。、,,。4,,。3 ,35℃,190dABR。2.16kg/(m3·d),COD(下转第4809页)478338卷9期 郭满芹 ABR反应器处理山梨酸废水的启动试验5 Fig.5 Thefactor-levelchangefigureofultrasonicextractingpeachseedoilexperiment。3 Table3 ThevarianceanalysisofultrasonicextractingpeachseedoilFactorsSumofsquareofdeviationsDegreeoffreedomFFvalueFCriticalvalueofF436.745314.452*9.280UltrasonictreatmenttimeSolid-liquidratio2.76530.0919.2801.20530.0409.280Extractiontime431.625314.283*9.280UltrasonicpowerError30.2203 3,,。,:35min,1∶6.0,1.0h,200W。2.3 5.0g,,,48.3%,20.1%(,)。,,。3 :;:,35min,1∶6.0,1.0h,200W,48.3%。[1]过国南,王力荣,阎振立,等.利用花粉粒形态分析法研究桃种质资源的进化关系[J].果树学报,2006,23(5):664-669.[2]康廷国.中药鉴定学[M].北京:中国中医药出版社,2003:336-337.[3]姜波,沙吾列,范圣第.桃仁油中脂肪酸的GC-MS分析[J].中国油脂,2008,33(11):71-72.[4]李婷,侯晓东,陈文学,等.超声波萃取技术的研究现状及展望[J].安徽农业科学,2006,34(13):3188-3190.[5]罗登林,丘泰球,卢群.超声波技术在油脂工业中的研究进展[J].粮油加工与食品机械,2005(3):48-50.[6]韩军岐,张有林,戴桂花,等.超声波处理提取葵花籽油研究[J].粮食与油脂,2004(9):24-25.(上接第4783页)93%,(VFA、pH)。ABR,pH2134。pH,ABR,。ABR,。1234。15mm,42mm。,,,,。[1]BACHMANNA,BEARDVL,MCCARTYPL.Performancecharacteristicsoftheanaerobicbaffledreactor[J].WatRes,1985,19:99-106.[2]LETTINGAG.Useofupflowsludgeblanketreactorconceptofbiologicalwastewatertreatment,especiallyofanaerobictreatment[J].Biotech.Bio-eng.,1980,22:669-737.[3]沈耀良,王宝贞.废水生物处理新技术———理论与应用[M].北京:中国环境科学出版社,1996:45-61.[4]孙剑辉,张波,彭云辉.新型高效生物处理技术———厌氧折流板反应器[J].工业水处理,2002,22(4):5-8.[5]BOOPATHYR,TILCEHEA.Anaerobicdigestionofhighstrengthmolasseswastewaterusinghybridanaerobicbaffledreactor[J].Wat.Res.,1991,25(7):785-790.[6]温俨,武果香.用BOD–COD相关原理分析排污废水可生化性[J].中国环境监测,1999(4):13.[7]冼萍,潘正现,张萍,等.山梨酸废水在ABR中的基质降解行为[J].环境工程学报,2008,2(5):633-637.[8]贺延龄.废水的厌氧生物处理[M].北京:中国轻工业出版社,1998:56-57.[9]邱波,郭静,邵敏,等.ABR反应器处理制药废水的启动运行[J].中国给水排水
