 Vol.34 No.11 2008175  ··—曹建平 杜 兵 刘 寅 秦永生(, 100037)   采用常温亚硝化—厌氧氨氧化工艺对淀粉废水生物处理出水进行生物脱氮处理,在SBR亚硝化反应器和气提式亚硝化反应器中均实现了稳定的半亚硝化反应。亚硝化—厌氧氨氧化工艺正常运行时,全流程总氮去除率基本维持在80%左右,最高达85.5%。一级亚硝化反应进水容积负荷为0.20kg/(m3·d),平均HRT为1.11d。厌氧氨氧化平均总氮进水容积负荷为1.11kg/(m3·d),最高达1.61kg/(m3·d);平均总氮去除负荷为0.83kg/(m3·d),最高去除负荷达1.29kg/(m3·d);平均HRT为0.20d。淀粉工业废水生物处理后出水中的有机物对亚硝化和厌氧氨氧化反应均未产生显著影响,所含过多的悬浮物和胶体物对亚硝化—厌氧氨氧化反应器存在潜在影响。 淀粉废水 常温亚硝化 厌氧氨氧化 生物脱氮  ,[1]。[3]。[4,5],。,,。—[6~9],。,,,,。,。[10],、,。SHARON[11,12],、HRT、pH,50%,,。SHARON—ANAMMOX[13],。—()参考文献1 HantutaJ,DennisH.Theefficiencyoftheproteindependentfloccu-lationofflavobactriumspissensitivetothecompositiongrowthme-dium.ApplMicrobialbiotechnol,1991,36:100~1042 ,,,..,2003,19(4):1~43 ,,,..,2005,25(11):14924 ,,,..,2007,27(4):68~705 ,,,..,2004,36(6):759~7626 ,..(),2004,(6):23~267 ..,2007,36(7):41~438 ,,,..,2007,29(2):30~359 ..,2006,33(5):10710 ..,2005,4(4):332~334  &:1500902601E-mail:mafang@hit.edu.cn:2008-04-21DOI:10.13789/j.cnki.wwe1964.2008.11.016176   Vol.34 No.11 2008。1 1.1 UASB—A/O,0~5℃。,,。:CODCr176.37mg/L,NH3—N201.41mg/L,NO-2—N2.99mg/L,NO-3—N0.87mg/L,pH8.36,1595.9mg/L,TSS1452.5mg/L,C/N0.88,。1.2 (1)SBR8.5L,200mm,280mm,,,、,。(2)—1,。23.8L,、,,,。(2.1L),。。1 —1.3 SBR,。SBR12h,11h,1h,,20~28℃,DO0.2mg/L。—。,HRT1d。,DO0.1mg/L。HRT0.32d,,HRT0.24d、0.16d、0.14d。,20~28℃。1.4 ,,;,,,2,。1.5 [14],,90%。2 2.1 SBR2.1.1 SBR2SBR(NO-2—N/NO-x—N)。105.51mg/L,120.86mg/L,,0.57%,97.65%,,SBR,,,。2 SBR、2.1.2 3SBRpH(ALK)。ALK/■NO-2—N9.92,,。5~7, Vol.34 No.11 2008177  68%,147.96mg/L,pH6.8~7.1,,,,,pH。3 SBRpH2.1.3 4CODCr。:,,,CODCr。,,,。4 SBR2.1.4 ,16d,,。■ALK/■NO-2—N,,。,CODCr,。,。,,。2.2 —2.2.1 ——(5、6),,1∶1.04,1.21%。,。HRT,,(DO0.1mg/L),,,。80%,83.11%,。7—。,178   Vol.34 No.11 20087 —80%,85.5%;3.57mg/L,6.42mg/L;31.61mg/L,75%。。14~21d:,,,,。。2.2.2 —(1)—。8—。,CODCr,,CODCr,,。97.62%,CODCr。CODCr,,CODCr,,8 —,CODCr。—。,,,—。(2)—。,,,。,,,10dMLSS3.9237g/L5.1613g/L,MLVSS/MLSS0.77630.7094,。,,。,,,,、。,—,。2.2.3 —9—。0.20kgN/(m3·d),0.27kgN/(m3·d);1.11kgN/(m3·d),9 — Vol.34 No.11 2008179  1.61kgN/(m3·d),0.83kgN/(m3·d),1.29kgN/(m3·d)。,HRT1.11d,,HRT0.20d,0.13d,。,,。,,80%。—“”[15]。,50%,0.10mg/L,2~3mg/L,40%。,。,,,,。3 (1)SBR,98%。—,。,80%,85.5%。(2)—,0.20kg/(m3·d),HRT1.11d。74.50%,83.11%;1.11kg/(m3·d),1.61kg/(m3·d);0.83kg/(m3·d),1.29kg/(m3·d);HRT0.20d。(3);—,。(4)—,,,。参考文献1 ,,..,2003,4(2):66~692 ,,.,2004,25():134~1373 ,,,..,2005,27(8):625~6294 ,,,..,2002,33(2):230~2355 .、.,2001,21(2):52~536 ,,..,2005,12(6):22~247 ,..,1999,19(3):139~1428 .UASB.,2000,31(2):31~339 ,,..,2002,21(3):139~14210 vandeGraafAA,deBruijnP,RobertsonLA,etal.Autotroph-licgrowthofanaerobicammonium-oxidizingmicro-organismsinafluidizedbedreactor,Microbiology,1996,142(8):2187~219611 HellingaC,SchellenAAJC,MulderJW,etal.TheSHARONprocess:aninnovativemethodfornitrogenremovalfromammo-nium-richwasterwater.WatSciTech,1998,37(9):135~14212 SchimdtI,SliekersO,SchimdM,etal.Newconceptsofmicrobi-altreatmentprocessesforthenitrogenremovalinwastewater.FEMSMicrobiolRev,2003,27(4):481~49213 vankempenR,MulderJW,UijterllndeCA,etal.Overview:fullscaleexperienceoftheSHARONprocessfortreatmentofrejectionwaterofdigestedsludgedewatering.WatSciTech,2001,44(1):145~15214 ..4.:,1997,252~27415 ,,,.—.,2005,7:64~67  ☆:10003759:(010)88362306E-mail:greenwish2004@126.com:2008-07-30:2008-08-14
