生物脱氮的短程硝化反硝化及影响因素李松良1,林华东2,王鹏1(1.重庆大学城市建设与环境工程学院,重庆400045;2.永川侨立水务有限公司,重庆402160)摘要:简要地介绍了短程硝化反硝化生物脱氮的机理,即控制氨氧化停留在亚硝化反应阶段,不经过硝化直接进行反硝化。总结了短程硝化反硝化的优点,并结合国内外的研究现状,对影响亚硝酸盐积累的主要因素进行了分析和探讨。关键词:短程硝化反硝化;亚硝酸盐积累;生物脱氮;氨氧化;影响因素中图分类号:X703文献标识码:B文章编号:1006-8759(2007)04-0016-04THEANALYSISOFTHEAFFECTINGFACTORSFORSHORTCUTNITRIFICATION-DENITRIFICATIONLISong-liang1,LIHua-dong2,WANGPeng1(1.ChongqingUniversityTheFacultyofUrbanConstructionandEnvironmentEngineering,Chongqing400045,China;2.YongchuanGlobalCreditWaterLimitedCo.,Chongqing402160,China)Abstract:Theprincipalofshort-cutnitrification-denitrificationisbrieflyintroducedinthispa-per,whichiscontrollingammonia-oxidationinthenitritereactionstageandstraightlyintothedenitrificationprocessbutnotthroughnitrificationprocess.Theadvantagesofshort-cutnitrifica-tion-denitrificationareanalyzed,thefactorsaffectingtheaccumulationofnitriteareanalyzedanddiscussedbasedonthepresentresearchliteratureinandbroad.Keywords:short-cutnitrification-denitrification;nitriteacculati
