ANAMMOX与反硝化协同脱氮反应器的启动特性研究李伙生

ANAMMOX李伙生,　周少奇,　孙艳波,　彭华平(华南理工大学环境科学与工程学院,广东广州510006)　　　:　向成功启动并已稳定运行2年的ANAMMOX反应器中连续添加有机物(葡萄糖),研究ANAMMOX与反硝化协同脱氮反应器的启动特性。结果表明,在短期内(35d)可成功启动ANAMMOX与反硝化协同脱氮反应器。启动过程可分为迟滞、适应和稳定运行三个阶段,在稳定运行阶段反应器对NH+4-N、NO-2-N、TN和COD的去除率分别高达95%、99%、94%和93%,NH+4-N去除量、NO-2-N去除量与NO-3-N生成量的比值为1∶1.32∶0.03,出水碱度和pH均略高于进水。　　:　厌氧氨氧化;　反硝化;　脱氮;　启动特性:X703　　:A　　:1000-4602(2009)21-0029-04Start-upCharacteristicsofANAMMOX/DenitrificationReactorLIHuo-sheng,　ZHOUShao-qi,　SUNYan-bo,　PENGHua-ping(CollegeofEnvironmentalScienceandEngineering,SouthChinaUniversityofTechnology,Guangzhou510006,China)　　Abstract:　Thestart-upcharacteristicsoftheANAMMOX/denitrificationreactorwereinvestigatedbycontinuousadditionoforganicmatter(glucose)intotheANAMMOXreactorthathasbeensuccessfullystartedupandoperatedstablyfor2years.Afaststart-up(35d)ofthereactorwassuccessfullya-chieved.Thestart-upperiodcanbedividedintothreemainphases,namely,thelagphase,theacclima-tizationphaseandthesteadyphase.Inthesteadyphase,theremovalefficienciesofNH+4-N,NO-2-N,TNandCODare95%,99%,94%and93%respectively.TheratioofNH+4-NremovaltoNO-2-NremovaltoNO-3-Nproductionis11.320.03,andtheeffluentalkalinityandpHareslightlyhigherthanthoseoftheinfluent.　　Keywords:　anaerobicammoniumoxidation(ANAMMOX);　denitrification;　nitrogenremoval;start-upcharacteristics　　:(20377013);　(2006B36703002);　(020959)　　(ANAMMOX),ANAMMOXNO-2-NNO-3-N,NH+4-NN2。[1、2],。ANAMMOX,[3]。[4],,ANAMMOXANAMMOX,·29·第25卷　第21期2009年11月　　　　　　　　　　　　中国给水排水CHINAWATERWASTEWATER　　　　　　　　　　　　　Vol.25No.21Nov.2009。ANAMMOX[5～7],。ANAMMOX。ANAMMOXANAMMOX,。1　材料与方法1.1　(1),3.2L,。,,,UASB(32±1)℃。1　ANAMMOXFig.1　SchematicdiagramofANAMMOXreactor1.2　,(NH4)2SO4NaNO2,,NaHCO3、KH2PO4。Ⅰ:EDTA5g/L,FeSO45g/L;Ⅱ:ZnSO4·7H2O0.430g/L,CuSO4·5H2O0.250g/L,MnCl2·4H2O0.990g/L,NiCl2·6H2O0.190g/L,CoCl2·6H2O0.24g/L,H3BO40.014g/L。Ⅰ、Ⅱ1.0mL/L。pH7.6～8.2。1.3　COD:;:;:N-(1-)-;:;:;pH:。1.4　TN260mg/L,1∶1.32,HRT24h。(),COD260mg/L,,。2　结果与讨论2.1　ANAMMOX2,、TN98%、99%85%,NH+4-N、NO-2-NNO-3-N1∶1.30∶0.26,[1]。,,。2.2　[4],ANAMMOXCO2NO-3-N,;CO2,AN-AMMOX,。ANAMMOX260mg/LCOD,COD2。·30·第25卷　第21期　　　　　　　　　　　　　　中国给水排水　　　　　　　　　　　　　CODFig.2　CODandnitrogenremovalcharacteristicsinthereactor2(a),COD3:(1～2d)、(3～35d)(36～55d)。,COD89%,52%。CODANAMMOX,COD,COD,COD,,,COD,COD。(3～23d)COD,45%～55%,,。,,COD,3589%。,COD93%,COD13～22mg/L。2(b),ANAMMOX,。2d,,96%;3～10,,3.53mg/L36.1mg/L,68.1%,ANAMMOX[3];10～2081.6%,ANAMMOX;,,2020.6mg/L3512.3mg/L,89.8%,95%。2(c),398.6%,,787.1%,ANAM-MOX;7,;1496%,2399%。,,。2(d),TN,7(73.9%),35TN90%,94%。,ANAMMOX(35d)ANAMMOX,:(1～2d)、(3～35d)(36～55d),、95%99%,TNCOD15.516.2mg/L,94%93%,。2.3　ANAMMOX,。Strous[1],ANAMMOXNH+4-N、NO-2-NNO-3-N1∶1.32∶0.26。,:(1～2d)、(3～35d)、(36～55d)。1∶1.33∶0.26,,ANAMMOX,·31·李伙生,等:ANAMMOX与反硝化协同脱氮反应器的启动特性研究第25卷　第21期。(3～16d),(α),1.85;(β)0.20,,。ANAMMOX[8],ANAM-MOX。(17～35d),β0.06,;α1.52,ANAMMOX,。,β0.03,αAN-AMMOX1.32,1.32。1∶1.32∶0.03,ANAMMOX。2.4　pHANAMMOXH+,,pH,ANAMMOX,。,2～7,,ANAMMOX,[4];10d。pH,8.72,,pH,8.32,(8.02),ANAMMOX,。3　结论①　ANAMMOXTN260mg/L,1∶1.32,HRT24h,()COD260mg/L,(35d)ANAMMOX,TNCOD15.5mg/L16.2mg/L,NH+4-N、NO-2-N、TNCOD95%、99%、94%93%,ANAMMOX。。②　,NH+4-N、NO-2-NNO-3-N1∶1.32∶0.03,pH,ANAMMOX,。:[1]　,,vanderStarWRL,.[J].,2007,23(18):15-19.[2]　,,,.[J].,2008,24(23):24-28.[3]　,,,.、pH[J].,2006,27(4):691-695.[4]　.[J].:,2006,34(5):1-4.[5]　BipinKP,FutabaK,YukoS,etal.Presenceandactivityofanammoxanddenitrificationprocessinlowammonium-fedbioreactors[J].BioresourTechnol,2007,98(11):2201-2206.[6]　,,.ANAMMOX[J].,2006,26(7):1087-1092.[7]　,.[J].:,2008,36(3):73-76.[8]　,,.[J].,2008,30(1):37-40.:(1984-　),　,　,　,　。:15913113496E-mail:[e-mail]::2009-04-22·32·第25卷　第21期　　　　　　　　　　　　　　中国给水排水
