双SBR脱氮除磷工艺的启动、特性试验与动力学分析(学位)

西安建筑科技大学硕士论文值)的值接近最大值O．5，造成吸磷反应停止。模拟分析的最佳碳氮比为3．75左右，低碳氮比造成反应器内聚磷菌与普通异养菌之间的比例降低，影响了系统的除磷效果。系统的碳磷比应大于15，碳磷比低于15时除磷效果恶化，是由XPt,／XpAo的值较高(接近于O．5)导致。关键词：双SBR、脱氮除磷、启动、污泥负荷、ASM2／Delf代谢模型、动力学分析II西安建筑科技大学硕士论文Researchonatwo-SBRsystemofdenitrifyingandBiologicalphosphorusremovalSpecialty：EnvironmentalEngineeringAuthor：HeXinghuiAdvisor：prof．wangzhiyingABSTRACTAtwo·SBRdenitrifyingandphosphorusremovingsystemwasstudiedinthisresearch．Theprocessehasmanyadvantages，suchashighefficiency，energysavingandlesssludgeetc．Sothenewtechnologyisbeingpainedmoreandmoreattentionbyenvironmentalengineeringexperts．FromtheexperimentsIgetthemainconclusionsasfollows．1．Duringthestart—upprocessoftwo—SBRsystemofdenitrilyingandBiologicalphosphorusremoval，TheinfluentconcentrationfilledofammoniumnitrogenshouldbeaccordingtothedenilrifyingabilityoftheDPB(Denitrifyingphosphorusremovingbacteria)，30～40mgN／Lisanappropriaterange．Consideringthestart—upprocessoftwO—SBRsystemofdenitrifyingandbiologicalphosphorusremoval，continuousfollowatA—SBRisbetterthantransientinfluent．2．Whenthesludgeloadingofsystemislow(0．5～0．69COD／gMLSS．d)，theoptimalC／Nvalueis3．75．Theremovalefficiencyofphosphorousis93．5％---100％．Whenthesludgeloadingishigh(1．26--0．969COD／gMLSS．d)，theopfimalvalueofC／Nis3．41．Theremovalefficiencyofphosphorousis700／o--96．6％．3．Thehi曲orpollutionloadofsludgemadethesystembecomemoresensitivetotheC／N．4．BasedontheASM2andDelftmetabolicallymodel，thepapersimulatedtheprocessofthetwO—SBRsystemofdenitrifyingandbiologicalphosphorusremoval．ThisstudyusedtheDelftmodeltOsimulatebio·PremovalandactivatedsludgemodelNo．2tosimulateCODandNremoval．ThefollowingsimulationsconfirmedexperimentconclusionthataninfluentbiodegradableC／N=3，75mgCOD／mgN，C／P>I5mgCOD／mgPand9～12disanidealrangeofSRT．Keywords：two·SBR；denitri母ingandphosphorusremoving；start-up；sludgeloading；ASM2／Delflmodel；kineticsanalysisIII声明y9'70618本人郑重声明我所呈交的论文是我个人在导师指导下进行的研究工作及取得的研究成果。尽我所知，除了文中特别加以标注和致谢的地方外，论文中不包含其他人已经发表或撰写过的研究成果，也不包含本人或其他人在其它单位已申请学位或为其它用途使用过的成果。与我一同工作的同志对本研究所做的所有贡献均已在论文中作了明确的说
