光合细菌法处理高浓度有机废水工艺探讨

光合细菌法处理高浓度有机废水工艺探讨黄翔峰1,李春鞠2,章非娟1(1.同济大学环境科学与工程学院,上海200092;2.中国水产科学研究院东海水产研究所农业部海洋与河口渔业重点开放实验室,上海200090):介绍了光合细菌的能量与物质代谢过程,并在此基础上探讨了光合细菌应用于废水处理时工艺条件的选择与控制由于光合细菌能高效利用废水中的低分子脂肪酸醇并具有多种代谢途径,因此在高浓度有机废水的处理中具有很大的优势:光合细菌;高浓度有机废水;可溶化;水解:X703.1:B:1000-4602(2005)02-0027-04DiscussiononthePhotosyntheticBacteriaProcessforTreatmentofHighStrengthOrganicWastewaterHUANGXiang-feng1,LIChun-ju2,ZHANGFe-ijuan1(1.SchoolofEnvironmentalScienceandEngineering,TongjiUniversity,Shanghai200092,China;2.KeyandOpenLabofMarinaandEstuaryFisheriesScience,EastChinaSeaFi-sheriesResearchInstitute,ChineseAcademyofFisheriesSciences,Shanghai200090,China)Abstract:Basedonmetabolismpathwaysofphotosyntheticbacteria(PSB),theprocessconditionandcontrolforthePSBintreatmentofhighstrengthorganicwastewaterwerediscussed.SincePSBarecapableofefficientlyutilizinglowmolecularweightfattyacidinwastewater,andsurvivingindifferenten-vironmentthroughvariousmetabolismpathways,PSBprocesswinsgreatsuperiorityintreatmentofhighstrengthorganicwastewater.Keywords:photosyntheticbacteria;highstrengthorganicwastewater;soluble;hydrolysis(PhotosyntheticBacteria,PSB),,1光合细菌的能量与物质代谢,(Bacteriochlorophylls,Bchl),(Purplesulfurbacteria)(Purplesulfurbacteria)(Purplenonsulfurbac-teria)g(Bacteriawithbchlg)(Greensulfurbacteria)(Mult-icellularfilamentousgreenbacteria)(AerobicchemotrophicBacteriawithbchl)CO22在处理高浓度有机废水中的应用127第21卷第2期2005年2月中国给水排水CHINAWATER&WASTEWATERVo.l21No.2Feb.20051Fig.1GeneralflowchartofPSBprocessfortreatmentofhigh-strenthorganicwastewater,,pH,,,,,,,1[1~7]1Tab.1EffectofPSBprocessinwastewatertreatment*/(mgL-1)/(mgL-1)/%/(kgm-3d-1)BOD58020320962BOD54050397900.7COD8020708912,COD16794**10589411.2**,COD5600**840856.7**BOD5628122439966.6UASB,BOD512250325973.1CODMn12100250983.3BOD511200195981.9CODMn13250526962.65BOD521553**1078952.4**COD3328235933.3COD224001247943.7,COD10500**395965.3**BOD510890**719933.6**COD250001450945.4,CODMn3960165960.99BOD51200204830.3FH-4,:*,**,1,,3光合细菌法工艺条件31,,,,,:;,H2S;,28第2期中国给水排水第21卷:,-300mV,-100~-300mV,+50mV;,,,;,,,[6],,,,323.2.1,2[8~11]2Tab.2EffectofPSBprocessunderdifferentluminanceandoxygenationconditionsinwastewatertreatment:,,:,,,;,,,:,H2S,;,,,3.2.21,,,,,,[7]3.2.3,:,0.5~1.0mg/L,[1]Sawada,(0.5%~1%),15%(),29第2期黄翔峰,等:光合细菌法处理高浓度有机废水工艺探讨第21卷,,[8]33,BOD,([12][26]),,,(),,,,(COD1096mg/L,BOD560mg/L),COD70%[13]4光合细菌法的优势,BOD51000mg/L,,,,,,,:[1],.[J].,1997,21(5):432-436.[2],,.[J].,1995,16(3):39-40.[3],,.[J].,1995,21(5):291-294.[4],,,.[J].,1998,18(2):173-175.[5],,.[J].,1999,(5):88-90.[6],,.[J].,1995,14(1):8-10.[7]WuShubin,LiangWenzh.iPurificationofAs-CMPe-ffluentbycombinedphotosyntheticbacteriaandcoagula-tiontreatment[J].JournalofEnviromentalSciences,2000,12(1):81-85.[8],,,.[J].(),1999,22(3):283-286.[9],,.[J].,2000,18(1):5-9.[10],.CMP[J].,1995,3(2):41-49.[11],.[J].,1999,16(2):17-19.[12],,,.[J].,1999,19(1):22-27.[13],.[J].,2001,19(1):6-10.:[phone]E-mail:[e-mail]:2004-09-2230第2期中国给水排水第21卷
