318 Vol.35 2009ASBR滕朝华1,2 安惠欣2(1, 710055;2, 100074) 采用恒压浮动盖式ASBR处理啤酒废水的研究表明,在中温35℃、容积负荷为1.5~7kgCODCr/(m3·d)、HRT为1d的条件下,CODCr去除率高于80%,平均沼气产率为410L/kgCODCr,气体中甲烷含量为50%~70%。ASBR运行2个月后污泥实现颗粒化,成熟颗粒污泥的直径为1.5mm,VSS/SS高达91%。试验期间甲酸的最大比产甲烷活性(SMA)达1.2gCODCr-CH4/(gVSS·d),8h后温度骤然升高至65℃,污泥变得松散,活性降低,但温度恢复正常后经过50天运行活性可完全恢复。 啤酒废水 ASBR 甲酸 颗粒污泥 、、、。COD、BOD、SS,。、。。2080,,,,。,、UASB。,、、SS,2090,IowaDague、———(AnaerobicSequencingBatchReactor,ASBR[1])。UASB,,SS,,[2]。ASBR,,,。ASBR,ASBR。ASBR,。,ASBR。3 (1),:pH、、。(2),:pH3.5,4h,60g/L,5∶1。CODCr46.7%。(3),。、,。参考文献1 ,,,.,,2002,(11):55~572 ,,.,,2003,34(6):52~533 ,,..,2007,38(6):28~304 ,,,.,,2003,31(4):47~525 .:[].:,2006 ☆:13032676506E-mail:lvjw3721@126.com:2009-03-04DOI:10.13789/j.cnki.wwe1964.2009.s1.021 Vol.35 2009319 ,。1 1.1 (1)45L,1200mm×330mm。1.3mm,,NaHCO3pH6.5,HRT1d,8h,40min,,440min,30min,10min,。1ASBR 2 3 4 5 6 7 8 9 101 ASBR1.2 ,CODCr12000~40000mg/L,TKN320~450mg/L,TP144~216mg/L,VSS1400~4800mg/L,pH3~3.9。NaHCO3pH6.5。1.3 UASB,SS22.51g/L,VSS8.39g/L,VSS/SS0.37,、、、0.1770gCODCr-CH4/(gVSS·d)、0.1076gCODCr-CH4/(gVSS·d)、0.0819gCODCr-CH4/(gVSS·d)0.0916gCODCr-CH4/(gVSS·d)。1.4 pH、COD、、MLSSMLVSS、,VFA[3],SMA[3]。2 2.1 CODCr2CODCrCODCr。,1.8kgCODCr/(m3·d),HRT1d,CODCr93%,,,CODCr73%,,CODCr,5kgCODCr/(m3·d),CODCr90%。216,5kgCODCr/(m3·d)7kgCODCr/(m3·d),VFA,851mg/L,3d5kgCODCr/(m3·d),CODCr,225CODCr87%。258,,,,8h65℃。50,7kgCODCr/(m3·d),CODCr75%。2 CODCrVFA2.2 VFA(VFA)[4],VFA,VFA,。VFA800mg/L,“”,。320 Vol.35 2009,VFA[5]。300,VFAVFA,300mg/L,100,VFA。216,VFA851mg/L,5kgCODCr/(m3·d)。358VFA1140mg/L,5.3kgCODCr/(m3·d),CODCr81%,VFA,。7.4kgCODCr/(m3·d),VFA1200mg/L,CODCr75%。1200mg/LVFA。2.3 ,,。[6]。3。,,0.41,,410L/kgCODCr。,50%~70%,。3 2.4 2.4.1 ,ASBR。,(4),,、,。,,,。,1.5mm(5)。,,,(6)。,、[7](7)。4 405 6 1307 10000 Vol.35 2009321 8 SVIVSS/SS2.4.2 SVIVSS/SS60d,SVI20mL/g51mL/g,28.9mL/g。,SVI,SVI。65℃,,SVI25mL/g,15.5mL/g;VSS/SS0.37,,VSS/SS,0.91,,,VSS/SS,SS,,,VSS/SS,980.84~0.88。2.4.3 SMA。1,ASBR0.478~1.09gCODCr-CH4/(gVSS·d)。。184SMA,、,,。65℃。1 /gCODCr-CH4/(gVSS·d)0.17700.10760.08190.09161081.21.121.161.011840.950.470.540.580.370.060.040.010.970.660.330.59 ,,,StamsFranck。Boone,(),,,,,,CODCr,CODCr。。3 ASBR,。8h65℃12h。1200mg/LVFA。410L/kgCODCr。1.5mm,VSS/SS91%。SMA1.2gCODCr-CH4/(gVSS·d)。参考文献1 DagueRR,BanikGC,EllisTG.Anaerobicsequencingbatchreactortreatmentofdilutewastewateratpsycrophilictemperatures.WaterEnvironmentResearch,1998,70(2):155~1602 ,.(ASBR).,2002,28(7):23~263 ..:,19984 ,.———.,2000,16(9):24~265 ..,2004,6(1):31~336 ,,.ASBR.,2004,27(3):94~977 MasseD,MasseL,VervilleA,etal.Thestart-upofanaerobicsequencingbatchreactorsat20and25forthetreatmentofslaughterhousewastewater.ChemTechnolBiotechnol,2001,76:393~4000 ☆:100074720134:13581613364E-mail:tengzhaohua77@sina.com:2009-02-18
