浸没式膜生物反应器的同步硝化反硝化效应齐　唯,　李春杰,　何义亮(上海交通大学环境科学与工程学院,上海200240)　　摘　要:　在浸没式膜生物反应器(SMBR)中,以人工配制的含氮废水作为原水,考察了在HRT为6h、SRT为50d、不同碳氮比(C/N)和DO条件下系统的同步硝化反硝化效应。结果表明:①在原水TN容积负荷为0.17kg/(m3·d)、C/N值为15、DO为1.0mg/L条件下,可获得81.2%的NH+4-N去除率和83.6%的TN去除率;②在原水TN容积负荷为0.36kg/(m3·d)、C/N值为10、DO为1.5mg/L条件下,可获得76.5%的NH+4-N去除率和52.8%的TN去除率。　　关键词:　SMBR;　C/N;　DO;　同步硝化反硝化中图分类号:X703.1　　文献标识码:A　　文章编号:1000-4602(2003)07-0008-04StudyonSimultaneousNitrificationandDenitrificationinSubmergedMembraneBioreactorQIWei,　LIChun-jie,　HEYi-liang(SchoolofEnvironmentalScienceandEngineering,ShanghaiJiaotongUniversity,Shanghai200240,China)　　Abstract:　Investigationwasmadeonthesimultaneousnitrificationanddenitrificationinasubmergedmembranebioreactor(SMBR)fedwithsyntheticwastewaterundertotalnitrogen(TN)volumetricloadingof0.17kg/(m3·d)and0.36kg/(m3·d)withdifferentcarbon-nitrogen(C/N)ratio.Thesludgeandhydraulicretentiontime(SRTandHRT)were50dand6hrespectively.Theresultshowedthat:(1)fortheTNvolu-metricloadingof0.17kg/(m3·d)ininfluent,removalrateofN
