ANAMMOX与反硝化协同脱氮反应器的启动特性研究李伙生,　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)　　摘　要:　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。　　关键词:　厌氧氨氧化;　反硝化;　脱氮;　启动特性中图分类号:X703　　文献标识码:A　　文章编号: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,therem
