SBR工艺脱氮除磷研究进展赵耘挚

SBR工艺脱氮除磷研究进展赵耘挚,　刘振鸿(东华大学环境科学与工程学院,上海200051)　　　:　概述了SBR脱氮工艺中的同步硝化/反硝化、亚硝化脱氮现象,讨论了影响SBR除磷的碳源、聚磷菌与非聚磷菌竞争、pH值、好氧曝气、污泥龄、水力停留时间等因素,并对SBR工艺中脱氮与除磷之间的相互影响进行了探讨,最后给出了可以同时脱氮除磷的一种SBR运行方式。　　:　SBR;　脱氮除磷;　强化生物除磷:X703.1　　:B　　:1000-4602(2003)03-0033-041　对SBR工艺脱氮的研究,,,,SBR;,SBR。[1],,DO0.5～1.5mg/L(),(),。HongWZhao、Lesley[2、3],,,、、,;,,BOD5/N6.9。[4]SBR(DO8mg/L)、MLSS,,,。:,,。,[5、6],、、、;,。、pH7.4～8.3、;,,。Sung-KeunRhee[7]SBR,:,,(,);,85%。2　对SBR工艺除磷的研究(EnhancedBiologicalPhosphorusRemoval,EBPR),,,。:①:(PAOs),(PHA),(ATP),;②:PHA、·33·　　　2003Vol.19　　　　　　　　　　CHINAWATER&WASTEWATER　　　　　　　　　　No.3,PHA。,,(PHA、、)。EBPR,“”,PHA。,PHA,。,SBREBPR,:2.1　,EBPR,COD/P≥35、BOD/P≥20。(VFAs),EBPREBPR;VFAs25mg/L,VFAs400mg/LEBPR;,PHA。2.2　,,,。Liu[8],,(GAOs),CheOkJeon[9],SBR、,EBPR,。Satoh[10],,,;,,PHA,PHA,,,。2.3　pHpH,pH。pH5EBPR,pH8.5～9.0EBPR。CheOkJeon[11],pH,pH7.0(8.0),,EBPR;pH,,pH8.4,EBPR,pH,ATP,,ATP。2.4　,PHA;,,,,EBPR。,PHA,[12]。2.5　,,;,,,。,,EBPR(3d)。2.6　,;EBPR,PHA。,/EBPR。3　SBR脱氮与除磷的相互影响SBR,,,。3.1　EBPREBPR,。,,。,2～5mg/L,,·34·2003Vol.19　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　No.3。,PHA。ChangCH[13],SBR10.9mg/L5.6mg/L,80%98%。Rusten[14],,10mg/L,。Pitman,5mg/L,,≥10mg/L,。Furumai[15],SBR,,。,COD。,,COD/TKN9。Tam[16],,,,。Ruya[17]SBR,COD,CODCOD;,COD、COD,,ASM3—。3.2　(DPAOs)EBPR,EBPR,,[18],,,,SVI[19],。3.3　Meinhold[20]SBR,,4～5mg/L,,,。,5～8mg/L,。4　SBR同时脱氮除磷运行方式的选择SBR,,,,,。,SBR1。1　SBR　　,;,;;,,;,[21]。:[1]　,,,./[J].,1999,15(6):58-60.[2]　HongWZhao,DonaldSMavinic,WilliamKOldham.Control-lingfactorsforsimultaneousnitrificationanddentrificationinatwo-stageintermittentaerationprocesstreatingdomestic·35·2003Vol.19　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　No.3sewage[J].WatRes,1999,33(4):971-978.[3]　LesleyARobertson.Simultaneousnitrificationanddentrifica-tioninaerobicchemostatculturesofthiosphaerapantotropha[J].AppliedandEnvironmentalMicrobiology,1998,54(11):2812-2818.[4]　,,.[J].,2001,27(1):22-24.[5]　.[J].,2000,26(11):21-23.[6]　,,.[J].,2001,21(11):11-13.[7]　Sung-KeunRhee,JayJLee,Sung-TaikLee.Nitriteaccumula-tioninasequencingbatchreactorduringtheaerobicphaseofbiologicalnitrogenremoval[J].BiotechnologyLetters,1997,19(2):195-198.[8]　LiuWT,MinoT,NakamuraK,etal.Roleofglycogeninac-etateuptakeandpolyhydroxyalkanoatesynthesisinanaerobic-aerobicactivatedsludgewithaminimizedpolyphosphatecontent[J].FermentBioeng,1994,77(5):535-539.[9]　CheOkJeon,DaeSungLee,JongMoonPark.Enhancedbio-logicalphosphorusremovalinananaerobic-aerobicsequenc-ingbatchreactor:characteristicsofcarbonmetabolism[J].WaterEnvironmentResearch,2001,73(3):295-300.[10]　SatohH,MinoT,MatsuoT.Deteriorationofenhancedbio-logicalphosphorusbythedominationofmicro-organismswithoutpolyphosphateaccumuluation[J].WatSciTech,1994,30(6):203-211.[11]　CheOkJeon,DaeSungLee,JongMoonPark.Enhancedbio-logicalphosphorusremovalinananaerobic-aerobicse-quencingbatchreactor:effectofpH[J].WaterEnvironmentResearch,2001,73(3):301-306.[12]　CYDassanayaka,RLIrvine.Anenhancedbiologicalphos-phorusremoval(EBPR)controlstrategyforsequencingbatchreactor(SBRs)[J].WatSciTech,2001,43(3):183-189.[13]　ChangCH,HaoOJ.Sequencingbatchreactorsystemfornutrientremoval:ORPandpHprofiles[J].JChemTechBiotechnol,1996,67:27-38.[14]　RustenB,EliassenH.Sequencingbatchreactorsfornutrientremovalatsmallwastewatertreatmentplants[J].WatSciTech,1993,28(10):233-247.[15]FurumaiH,KazmiAA,FuruyaY,etal.Effectofsludgere-tentiontime(SRT)onnutrientremovalinsequencingbatchreactor[J].JournalofEnvironmentalScienceandHealthpartA,1999,34(2):317-328.[16]　TamNFY,WorngYS,LeungG.Effectofexogenouscar-bonsourcesonremovalofinorganicnutrientbythenitrifica-tion-denitrificationprocess[J].WatRes,1992,26(9):1229-1236.[17]RuyaTasli,DerinOrhon,NazikArtan.Theeffectofsubstrateconpositiononthenutrientremovalpotentialofsequencingbatchreactors[J].WaterSA,1999,25(3):337-344.[18]　,,.[J].,2001,20(11):556-557.[19]　KubaT,vanLoosdrechtMCM,HeijnenJJ.PhosphorusandnitrogenremovalwithminimalCODrequirementbyintegra-tionofdenitrifyingdephosphatationandnitrificationinatwo-sludgesystem[J].WatRes,1996,30(7):1702-1710.[20]　MeinholdJ,ArnoldE,IsaacsS.Effectofnitriteonanoxicphosphateuptakeinbiologicalphosphorusremovalactivatedsludge[J].WatRes,1999,33(8):1871-1883.[21]　,.SBR[J].,2000.16(7):23-25.:[phone]E-mail:[e-mail]:2002-09-08·36·2003Vol.19　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　No.3
