EGSBSPMBR工艺深度处理高浓度豆制品废水周保昌

EGSB/SPMBR周保昌,　孙　凯,　陆晓峰,　卞晓锴,　李景烨(中国科学院上海应用物理研究所,上海201800)　　　:　采用厌氧膨胀污泥床/浸没式平板膜生物反应器(EGSB/SPMBR)组合工艺深度处理豆制品废水。结果表明:EGSB和SPMBR工艺均具有抗冲击负荷能力强、容积负荷率高、对有机物的去除效果好等特点。在厌氧消化作用下,EGSB对有机物的去除起到主要贡献,为后续单元的运行提供了良好条件;而SPMBR在进一步降解有机物和确保系统稳定运行方面发挥着重要作用,两者的有机结合可获得理想的有机物去除率。在中温(32～37℃)条件下,EGSB的容积负荷可达10kg/(m3·d),对有机物的去除率85%,对总氮的去除率在35%左右;SPMBR在环境温度15℃的条件下对有机物的去除率仍可达95%以上,出水COD50mg/L,对氨氮的平均去除率在35%左右,对总氮的去除率在30%～60%之间。　　:　厌氧膨胀污泥床;　浸没式平板膜生物反应器;　豆制品废水;　深度处理:X703　　:A　　:1000-4602(2010)17-0019-04　　:(08231200300)EGSB/SPMBRProcessforAdvancedTreatmentofHighStrengthSoybeanProcessingWastewaterZHOUBao-chang,　SUNKai,　LUXiao-feng,　BIANXiao-kai,　LIJing-ye(ShanghaiInstituteofAppliedPhysics,ChineseAcademyofSciences,Shanghai201800,China)　　Abstract:　Thecombinedprocessofexpandedgranularsludgebed(EGSB)andsubmergedplatemembranebioreactor(SPMBR)wasusedforadvancedtreatmentofsoybeanprocessingwastewater.TheresultsshowthatbothEGSBandSPMBRhavethefeaturesofgoodimpactresistance,highvolumeloadandhighremovalefficiencyoforganicsubstances.Underanaerobicdigestion,EGSBhasamajorcontri-butiontoremovaloforganicsubstances,whichprovidesgoodconditionfortheoperationofsubsequentu-nits.SPMBRplaysanimportantroleinfurtherdegradationoforganicsubstancesandensuringthestabili-tyofwholesystem.Theintegrationofthesetwoprocessescanachieveanidealremovalefficiencyofor-ganicsubstances.Attemperatureof32to37℃,thevolumeloadofEGSBcanreach10kg/(m3·d),theremovalratesoforganicsubstancesandTNareabove85%andabout35%.Atambienttemperatureandevenlessthan15℃,theremovalratesoforganicsubstances,ammonianitrogenandTNinSPMBRareabove95%,about35%and30%to60%,andtheeffluentCODisbelow50mg/L.　　Keywords:　expandedgranularsludgebed(EGSB);　submergedplatemembranebioreactor(SPMBR);　soybeanprocessingwastewater;　advancedtreatment　　,。COD·19·第26卷　第17期2010年9月　　　　　　　　　　　　中国给水排水CHINAWATERWASTEWATER　　　　　　　　　　　　　Vol.26No.17Sep.201010000～20000mg/L[1],,。(EGSB)(UASB),、[2],。(SPMBR)[3～5],,,、,。EGSB/SPM-BR,COD、BOD5、NH3-NTN,。1　材料与方法1.1　,:COD1000～12000mg/L,BOD5/COD0.45～0.75。1.2　EGSB/SPMBR1。1　Fig.1　FlowchartofEGSB/SPMBRprocessEGSB,200cm,25cm,98L,,32～37℃;SPMBR、,96L,PVDF,1m2,200L/d。1.3　EGSB,12.69g/L,1/3。EGSB,,COD1000mg/L,0.5kgCOD/(m3·d)。80%,,30%。EGSBSPMBR。SPMBREGSB,6000mg/L,1/3。,,。2　结果与讨论2.1　CODEGSBCOD1000mg/L,180d,EGSB/SPMBR100。,EGSB,,COD70%～80%,EGSB,85%。160COD12000mg/L,COD1500mg/L,88%。,COD,COD,,10kg/(m3·d)。SPMBR、COD2。2　SPMBR、CODFig.2　VariationsofCODconcentrationsininfluenteffluentofSPMBR,SPMBRCOD,COD1000～1300mg/L,COD25～50mg/L;·20·第26卷　第17期　　　　　　　　　　　　　　中国给水排水　　　　　　　　　　　　。。,SPMBRCOD,,。2.2　BOD5EGSBBOD585%。BOD5,BOD5,EGSB。166,BOD57000mg/L,,BOD5,1802100mg/L,3.5kgBOD5/(m3·d)。EGSBSPMBR,EGSBBOD57000mg/LBOD520mg/L。,EGSB/SPMBRBOD599%。2.3　NH3-N、、,。EGSBNH3-N(80～300mg/L),,,NH3-N(200～320mg/L)。SPMBR,30%～60%,:①,,,;②,15℃,。,,[6]。2.4　TNEGSBSPMBR,TN,3。EGSB,,。3(a),EGSBTN30%～40%,,。3　EGSB/SPMBRTNFig.3　TNremovalefficienciesinEGSBandSPMBR,BOD5/TKN5,0.054%[7]。SPMBRBOD5/TKN5,30%～60%。SPMBR(20d),,[8、9]。3(b)SPMBR,,。3　结论①　EGSB/SPMBR,。②　EGSB/SPMBR,,SPM-BR。:[1]　,,.·21·周保昌,等:EGSB/SPMBR工艺深度处理高浓度豆制品废水第26卷　第17期[J].,2007,23(3):461-464.[2]　LettingaG,FieldJ.Advancedanaerobicwastewatertreat-mentinnearfuture[J].WaterSciTechnol,1997,35(10):5-12.[3]　,,.[J].,2005,23(6):13-15.[4]　,,,.[J].,2008,24(19):55-57.[5]　,,,.SMBR-IVCW[J].,2008,28(9):1785-1792.[6]　FuZhimin,YangFenglin.Simultaneousnitrificationanddenitrificationcoupledwithphosphorusremovalinanmodifiedanoxic/oxic-membranebioreactor(A/O-MBR)[J].BiochemEngJ,2009,43(2):191-196.[7]　,.()[M].:,1989.[8]　StephensonT,JuddS,JeffersonB,etal.MembraneBio-reactorsforWastewaterTreatment[M].London:IWAPublishing,2000.[9]　TanTW,NgHY.Influenceofmixedliquorrecycleratioanddissolvedoxygenonperformanceofpre-denitrificationsubmergedmembranebioreactors[J].WaterRes,2008,42(4-5):1122-1132.:(1981-　),　,　,　,　,　。E-mail:[e-mail]::2010-04-22(上接第18页)2002B。4　TPTab.4　TPremovalefficiencyatthirdphase/(mg·L-1)4.24.77.56.78.78.95.67.78.65.8/(mg·L-1)0.630.700.670.450.620.700.500.680.590.53/%85.085.191.193.392.992.191.191.293.190.93　结论①　A2/O,0.278gMLSS/gCOD,A2/O37.9%,。②　A2/O,TN≤14.6mg/L、TP≤1.31mg/L,A2/O,TN3.84%,TP2.87%。③　A2/O,COD≤55mg/L、TN≤14.6mg/L、TP≤0.70mg/L,《》(GB18918—2002)B。A2/O,TN3.84%,TP2.42%,0.278gMLSS/gCOD,37.9%。:[1]　,,,.LSPPNR[J].,2007,23(3):35-39.[2]　,./[J].,2005,25(2):34-37.[3]　,.[J].:,2008,31(12):2038-2040.[4]　,,.[J].,2006,25(1):74-78.[5]　,,,.[J].,2008,24(24):83-86.:(1969-　),　,　,　,　。E-mail:[e-mail]:2010-03-15·22·第26卷　第17期　　　　　　　　　　　　　　中国给水排水
