反硝化除磷工艺及其微生物学原理张宝

反硝化除磷工艺及其微生物学原理　(唐山市规划设计研究院,河北唐山063000)　:反硝化除磷是通过反硝化聚磷菌的代谢作用,同时完成过量吸磷和反硝化过程,在达到同步生物脱氮除磷的目的同时,解决了生物脱氮和生物除磷之间相对独立的、相互竞争的矛盾。就此项新技术的微生物学原理及其新工艺进行了重点介绍。:反硝化除磷;反硝化聚磷菌;缺氧;厌氧:X703　　:A　　:1009-3230(2007)08-0005-03ResearchProgressandMicrobiologyPrincipleonDenitrifyingDephosphorizationTechnologyZHANGBao(TangshanInstituteofUrbanPlanningandDesign,HeBei,063000)Abstract:ThetechnologyofdenitrifyingandphosphorusremovalcarriesouttheprocessofPhosphateex-cessiveuptakeanddenitrificationbymetabolismofdenitrifyingphosphate-accumulatingorganisms.ItachievedbiologicaldenitrifyingandphosphorusremovalandresolvesaproblemthatCompetitionexistsinthecourseofdenitrifyingandphosphorusremovalsimultaneously.Itsmicrobiologyprincipleandnewlyde-velopeddenitrifyingdephosphatationprocessisdiscussedindetail.Keywords:Denitrifyingandphosphorusremoval;Denitrifyingphosphate-accumulatingorganisms;Anoxic;Anaerobic0　引言,。,,。,———,。,,()()[1]。,,30%50%[2],,(VFAs)。1　反硝化除磷微生物学原理:2007-06-15　　:2007-07-10:(1974～),,,。,()、12。1　,PHB,。CoA,,,;PHB,520078(116)　　　　　　　　　　　　　　　　　　　　　　　　　,NO-3。,,,,[3]。O22/3,,;,。,。,,[4]。2　TCA　　2,,HAc[5]:TCA。,(),,,PHB。,,。PH,HAc。,HAcCoAATP,。,TCA。PH,HAc,,。,TCA。,。,ATP。。,,PH。,,,。,,ATP,CoA。APHB。,PHB。Mino(1987)EMP(),PHB,:CH2O+0.083C6H10O5(CH)+0.44HPO32-+0.023H2O※1.33CH1.5O0.5(PHB)+0.17CO2+0.44H3PO4,PHB,。,,ATP,。,PHB,TCAATP,。,,6　　　　　　　　　　　　　　　　　　　　　　　　　　20078(116),PHB。,PHB,。PHB,。,,。2　反硝化除磷工艺介绍2.1　BCFSKluyveUCTBCFS,3,BCFSUCT2,UCT,,COD。,UCT,,。,BCFS2QeQc,Qe,,Qc,,。BCFS,,,BCFS。3　BCFS2.2　DEPHANOXBCFS,,,BCFSBCFS。KUBADEPHANOX,4。,-β-(PHB),。NH-3-N;4　DEPHANOXPHB。,;。,。;。,。,,,。3　结语,COD。,,。[1]　KubaT,SmolderG,vanLoosdrechtMCM,etal.Biolog-icalPhosphorusRemovalfromWaste-waterbyAnaerobic-AnoxicSequencingBatchReactor.WaterSciTech-nol.,1993,27(5-6):241-252.[2]　MMerzouki,NBernet,JPDelgenes,etal.BioloicalDenitrifyingPhosphorusRemovalinSBR:EffectofAddedNitrateConcentrationandSludgeRetentionTime.Wat.Sci.Tech,2001,43(3):191-194.[3]　SmoldersGJD.ModeloftheAnaerobicMetabolismoftheBiologicalPhosphorusRemovalProcess:StoichiometryandPHInfluence,BiotechnologyandBioengineering,1994,1(43):461-470.[4]　Arvin.E.,Kristensen,G.H.ExchangeofOrganics,Phos-phateandCationsBetweenSludgeandWaterinBiologicalPhosphorusandNitrogenRemovalProcesses.Wat.Sci.Technol.,1985,1(7):147-162.[5]　TomonoriMatsuo.MetabolismofOrganicSubstancesinAnaerobicPhaseofBiologicalPhosphateUptakeProcess,Wat.Sci.Tech.,1992,25(6):83-92.720078(116)
