城市污水除磷脱氮MSBR工艺试验研究＊　　　　　　　　＊(96-909-01-02-05)李春鞠　顾国维　杨海真(,200092)　MSBR系统是一种新型的生物脱氮除磷工艺,它介于连续流和序批操作之间。采用容积2.6m3的MSBR系统中进行了3个工况的水力负荷试验,研究了系统的除磷脱氮效果及其影响因素。由于系统的特点,当进水碳磷比较低时,系统仍有良好的除磷效果。但遇持续降雨时,大量雨水进入合流污水,进水中有机物浓度急剧下降会导致除磷效果恶化。由于采用后置反硝化形式,MSBR系统的反硝化阶段无法得到充足的外碳源,脱氮率受到限制。　MSBR　生物脱氮　生物除磷1　,。1998———MSBR(ModifiedSequencingBatchReactor)。Bardenpho、UCT,,、、,。2.6m3MSBR6,。2　2.1　试验装置及主要设备(1)MSBR　。1。1　MSBR(2)/L350860570×218070　　(2)　。,PLC;,。(3)　。(4)　,,。2.2　工艺流程和周期运行情况　MSBRMSBR2:(1)SBR1,A,“-SBR1----”((a),R1、R2)。,,,SBR1,,C,。SBR2,。(2)SBR1,,、19　　　200012186DOI:10.13205/j.hjgc.2000.06.006SBR2((b)),SBR1,。,SBR2、,SBR1。,22h,MS-BR。2。2　MSBR/min504030504030SBR1SBR2ACB2.3　试验水质。,CODCr/TKN4.87,CODCr/TP51.3,,CODCr/TKN9,CODCr/TP60。,,,3。3　CODCrBOD5/mg·L-1200～400100～13020～5030～802～7.5/mg·L-11005015151.52.4　试验内容MSBR,。4。4　12399.3.2～99.4.3099.5.1～99.6.199.6.2～99.7.1/℃10.6～20.321.5～24.620.4～29.3/L·h-1205288375/h12.689.036.93/mg·L-10.10.2～0.31.0～1.50.3～0.5/mg·L-13926299131012.62.11.61.61.20.8:,,,。3　3.1　CODCr的去除效果,CODCr,CODCr50mg/L。,,,(5)。5　CODCr()123CODCr/mg·L-1331.0243.9205.8CODCr/mg·L-143.934.623.9%86.183.986.8/kg·(kg·d)-10.210.290.30/kg·(m3·d)-10.830.860.95　　,CODCr。,。16.5℃、CODCr373.6mg/L,17.14mg/L,25.71mg/L,9.60mg/g·h。,PHB(β),CODCr。60%～90%[1～3]。6,MSBRCODCr0.14mg/g·h,CODCr0.086～0.19mg/g·h[4、5]。6　、CODCr/mg·L-1251.027.36251.0251.026.56251.0251.042.66251.0/mg·L-127.3619.3216.1026.5617.7112.6842.6617.5019.11:1.。2.、CODCr。MSBRCODCr(),(PHB),,,20　　　200012186。3.2　总氮的去除效果,。2.3h(3),5mg/L,90%。1,MSBR。,,,。(7),。7　()　　　23/h9.036.93/h0.300.30/mg·L-155.436.2/mg·L-112.013.3%76.859.9:,1。,MSBR,。MSBR。[6]3.3　总磷的去除效果,(8)。,,,。8　()　　123/mg·L-15.504.973.99/mg·L-10.500.930.81%90.275.475.9(CODCr/TP)60.248.851.6　　CODCr/TP60,。1,。2、3,。,(1mg/L),;,4～5d。:、,。PHB,PHB,。,CODCr,,,[7]。,,,PHB,。,[8]。(GlycogenAccumulatingOrganisms,GAOs),。,,[9]。。MSBR。、,,,0.6mg/L。,MSBR,。60,1mg/L。4　(1)MSBR。0.23～0.30kg/kg·d,6.9～12.7h,CODCr,20mg/L1mg/L。(2)MSBR。,。,。(6.9～9.0h),,MSBR60%～78%。(3)()。CODCr/TP60,,90%;CODCr/TP60,。21　　　200012186,,。(4),,,,MSBR。CODCr/TP60,1mg/L。1　.-COD.,1997.23(6):12～15.2　AnaMunoz-Colungaetal.EffectsonPopulationDisplacementsonBio-logicalPhosphorusRemovalinaBiofilmSBR.Wat.Sci.Tech,1996.34(1～2):303～313.3　A.Caruccietal.DifferentMechanismsfortheAnaerobicStorageofOrganicSubstratesandTheirEffectonEnhancedBiologicalPhospho-rusRemoval(EBPR).Wat.Sci.Tech,1999.39(6):21～28.4　PamirBrnjaoovicetal.InfluenceofTemperatureonBiologicalPhos-phorusRemoval:ProcessandMolecularEcologicalStudies.Wat.Res,1998.32(4):1035～1048.5　D.Brdjanovicetal.ImpactofExcessAerationonBiologicalPhospho-rusRemovalfromWastewater.Wat.Res,1998.32(1):200～208.6　.MSBR.,2000.1.7　HansCarlssonetal.InteractionbetweenwastewaterQualityandPhos-phorusReleaseinAnaerobicReactoroftheEBPRProcess.Wat.Res,1996.30(6):1517～1527.8　..,1997.15(6):13～16.9　Wen-TsoLiuetal.GlycogenAccumulatingPopulationandItsAnaero-bicSubstrateUptakeinAnaerobic-AerobicActivatedSludgewithoutBiologicalPhosphorusRemoval.Wat.Res,1996.30(1):75～82.　,,19742。20003,。2000-05-20　　　　　　　　＊(59708005);采油废水中硫酸盐还原菌的二氧化氯杀灭实验研究＊黄廷林(,710055)　张　刚(,710048)裴润有　马忠孝(,745100)　废水中硫酸盐还原菌(SRB)所造成的注水系统的腐蚀、结垢和阻塞严重影响着原油的开发与生产。以二氧化氯作为氧化型杀菌剂杀灭SRB的实验结果表明,ClO2对SRB具有很强的灭菌能力;ClO2投量C1.0mg/L时就能满足回注水的要求;适宜的接触反应时间为t4.0min;相应地有Ct4.0;对ClO2的杀菌机理进行了探讨,研究成果将为今后油田水处理工艺的改造提供理论依据和技术支持。　采油废水　硫酸盐还原菌(SRB)　二氧化氯　灭菌1　、11[1],4(SRB),SRB,。,SBR。,、[2]。,,SRB,,ClO2SRB。2　SRB[3～6],()、、、,SRB22　　　200012186theexperimentalresultsindicatedthattheinternalloopcouldbebeneficialtogas-liquidtransferandefficientforbrewerytreatment.Keywords　bioreactor,brewerywastewater,contactaeration,internalloopandairliftPILOTSTUDIESONBIOLOGICALNUTRIENTREMOVALBYSIX-ZONEMSBRLiChunjuetal(19)……………………………………………………………………………………………………………………Abstract　MSBR(ModifiedSequencingBatchReactor)isanewdevelopedBiologicalNutrientRemovaltech-nology,whichisquitedifferentfromtheothertransformationsofSBR.Itsstructuremadeithasthecharacteristicsofsmallplotarea,moreflexibilityinoperationautomaticcontrolandetc.Experimentshaveconductedina2.6m3six-zoneMSBRsystemsoastoinvestigateitsefficiencyundervarioushydraulicloads.Thesystemisprovedtohaveareliableperformance,evenwhenaninfluenthasalowerCODCr/TP.Howevercontinualrainledtoatemporaryin-creasedphosphorusconcentrationintheeffluent.Duetothepost-denitrificaionstructure,nitrogenremovalislimitedbytheinsufficientcarbonsource.Keywords　MSBR,biodenitrificationandbiologicalphosphorusremovalANEXPERIMENTALSTUDYONKILLINGSULFATE-REDUCINGBACTERIA(SRB)BYCHLORINEDIOXIDEINOILPRODUCTIONWASTEWATERHuangTinglinetal(22………………………………)Abstract　Sulfate-ReducingBacteria(SRB)inwatercancausecorrosion,scaleandbarricadetothewaterin-jectionsystem.Sointheprocessofoilproductionwastewatertreatment,thedisinfectionsofSRBbecomeveryim-portant.OnthebasisofexperimentalstudyondisinfectionsofSRBbychlorinedioxide,theoptimumoperationcon-ditionsareobtainedas:ClO2dosageC1.0mg/L,reactiontimet4.0minandCt4.0.AlsotheconcernedmechanismofkillingSRBbyClO2isfurtherexpounded.Keywords　oilproductionwastewater,SRB,chlorinedioxideanddisinfectionsEMERGENCEOFACTIVATEDSLUDGEFLOATATIONANDITSCONTROLINAC
