北方寒冷地区SBR设计参数的修正及其探讨韩洪军

SBR＊韩洪军　梁　杰　马文成(,150090)　在城市污水处理系统中,通常的SBR工艺设计参数多适用于常温的环境即15～30℃。而我国北方寒冷地区,冬季水温一般在6～10℃,如果仍按照常规参数进行工程设计,在一定程度上不能满足北方城市污水处理系统的实际情况,出水水质很难达到排放要求。因此,应把温度参数与反应动力学联系起来,通过试验和工程实例对SBR的常规设计参数进行低温下的修正,以适应北方寒冷地区的城市污水处理厂的设计要求。　SBR　低温　设计参数　修正　　　　　　　　＊(2003AA601090)0　SBR,,。,,,[1,2],SBR,,。,,,SBR(BOD5,,、),,,。1　BOD5BOD5、。[3]:,。10℃,BOD50.08kg(kg·d)。,0.11kg(kg·d),0.2kg(kg·d)。,,,BOD5,,,BOD5。,7～9℃,17～19℃。,BOD50.11kg(kg·d),BOD5CODCr,,,。,BOD50.20kg(kg·d),BOD5CODCr,0.30kg(kg·d),BOD570%,0.45kg(kg·d),35%。,,2℃,,4.2～7.7℃,BOD5(0.1kg(kg·d)),,BOD577%～90%,CODCr56%～60%,[5]。SBR,,10℃,、。Ns=KT·Se·fη(1)　Ns———T℃BOD5　kg(kg·d);KT———T℃BOD5　Ld,;Se———5　mgL;f———MLVSSMLSS,0.70～0.75;84　　　20064242DOI:10.13205/j.hjgc.2006.02.030η———5,0.85～0.90。SBRT℃,BOD5KT:KT=K20·θT-20(2)　　K20———20℃5,,0.013～0.019;　　θ———,,、。,。,。θ,。,,θ。,5～7℃,,。θ1。1　℃θ6～211.0316～311.04910～211.01110～17.51.01327.5～17.51.02665～17.51.06937.5～17.51.065610～251.02510～261.022　　,SBR,BOD50.11kg(kg·d),BOD5K20θ,。2　ΔX,,。a(1),20℃a,0.3451,30℃,0.3123,0.33。a。b,,,θb=1.0134,1　ab20=0.0662。bT=0.0662·1.0134T-20(3)　bT———T℃　1d。,,、、、。、、a、b2,。2　a、b℃ab℃ab℃ab40.3940.00760.32830.055560.4310.012110.32780.05738～100.480.0295100.4790.025150.33700.0633150.6070.045200.34510.0695200.6140.058250.32700.069515～200.5120.0630250.5220.091300.31320.0766　　a、b,,。SBR、,,。,,a、b,,。3　SBRSBR,,。:dcdt=kla(Ca-C)(4)　dcdt———dtC;Kla———　1h;Ca———　mgL;C———　mgL。,2,Kla,85　　　20064242(Ca-C),2。,,。,,Ca,Ca-C,,,,,,2。2　,,,,。3,BOD50.2kg(kg·d),20℃5℃2。SBR,,。,[4]。3　　4　SBR,15℃5℃5.51mmmin、3.64mmmin,,。,。,,,,,SVI,。,,,。SBR,Vs:Vs=650(MLSS×SVI)(5)　Vs———　mh;MLSS———　kgm3;SVI———　mLg。,SBR,SS,SVI。70～100mLg,,,SVI。,,150～180mLg[5,6]。5　,[7～9],3。3　　　BOD5(kg·kg-1·d-1)0.15～0.40.03～0.15MLSS(mg·L-1)1500～50003～4214～1215～13cm50(kg·kg-1)0.5～1.50.8～1.0(kg·kg-1)10.75d≥10≥15h4～66～8h1～1.51.5～3SVI(mL·g-1)70～100150～180(m3·m-2·h-1)1.0～1.50.5～1.06　,,SBR。SBR,。,,,BOD50.11kg(kg·d),,,,。[1]　,.().,1984,(1):11-16.86　　　20064242[2]　,.().,1984,(2):19-22.[3]　BasimAzizsaysigh.Temperatureeffectsontheactivatedsludgeprocess.WPCE,1978.4.[4]　,,..,1971.[5]　,..,2002,28(5).[6]　,,,..,2003,19(2):5-7.[7]　.のになよのよゐ.,1977,9.[8]　..:,2002.[9]　..1990.　　150090　　2082005-05-16万金颖　纪玉琨　巨振海(,065000)　李广贺(,100084)　通过对北运河香河段污灌区不同深度土壤重金属Cu、Pb、Zn、Cd含量的监测分析,评价污灌对土壤重金属含量造成的影响。结果表明,土壤中重金属含量和土壤理化性质、土壤深度以及污灌时间、污灌水重金属含量直接相关。　污水灌溉　重金属　　,20.4km,237.5km2,30[1],670m3hm2,[2]。,、,[3],,,、、、、、、、[4-6],,。,,Cu、Pb、Zn、Cd。1　1.1　采样方法,100m,1990《1∶50》“,10～40cm,km22”。0～20cm20～40cm。1.2　样品前处理2g,100mL,,15mL,,,4mL,,,,(,,),,1%,25mL,。,5%、10%10%。2　2.1　土壤重金属随空间变化特征分析,,,———,———。,,、———(87　　　20064242TECHNICALINNOVATIONDESIGNOFMULTIPURPOSEUSEOFASHWATERANDCHEMICALREGENERATEDWATERFORATHERMALPOWERPLANTFangXi　ZhangGehong　HanYaoxiaetal(77)……………………………………………………………………………………………………………Abstract　Ithasbeencompletelydiscussedthemultipurposeuseofbothashwaterandchemicalregeneratedwatercomingfromathermoelectricplant.Throughoptimizingtherunningwayofashwaterandchemicalregeneratedwater,theindustrialwatersupplycanbereduced,andnodischargecanberealizedtoo.Savingthecostandprotectingenvironmentwillbeachievedatlast.Aftertechnicalinnovation,thewaterof684,830m3canbesavedyearlywithabenefitof890,830yuanperyear.Keywords　ashwater,chemicalregeneratedwater,industrialwatersupplyandtechnicalinnovationTREATINGHIGH-SALINITYWASTEWATEROFPROCESSINGMARINEPRODUCTSBYSBRQiuQiaojun　YinWei　LǜMouetal(79)……………………………………………………………………………………Abstract　Sequencingbiologicalreactorisadoptedtotreathigh-salinitywastewaterofprocessingmarineproducts.Theresultsshowthatitisfeasibletotreatthewastewaterinwhichtheproportionofseawaterisnomorethan50percentandsequencingbiologicalreactorcanresistthehigh-salinityimpactload.WhentheinfluentCODCr=700～1000mgL,NH3-N=80～120mgLand[Cl-]≤8000mgL,theremovalratesofbothCODCrandNH3-Nintheeffluentare77.9%～81.2%and69.5%～76.6%respectively.Withtheincreasingof[Cl-],theSBRsystemisaffectedseriouslyandtreatingeffectisworsened.Keywords　high-salinity,wastewaterofprocessingmarineproductsandsequencingbiologicalreactor(SBR)RESEARCHONPRESSUREREGULATIONANDENERGYCONSUMPTIONINCIRCULATEDFLUIDFIELDSYSTEMSGuoAiqing(81)……………………………………………………………………………………Abstract　Aseriesofexperimentswascarriedoutwithfluidmechanicsexperimentalmethodstostudythegaspressure,theregulationoffluidflowvariation,energyconsumptionoftheventilatorintheverticallycirculatedwindtunnel.Researchonpressureregulationandenergyconsumptionincirculatedfluidfieldsystemswascarriedout.Theresultofthisprojectmaybeagoodreferenceforotherprojectsandontheotherhanditwillprobablybebeneficialtopromotingdesignqualityinventilatingsystems.Keywords　circulatedfluid,pressureregulation,flowcontrolandenergyconsumptionDISCUSSIONONCORRECTIONOFSBRDESIGNPARAMETERSINARCTICREGIONHanHongjun　LiangJie　MaWencheng(84)…………………………………………………………………………………………Abstract　SBRdesignparametersforsewagetreatmentsystemaresuitablefornormaltemperatureenvironment(15～30℃);yetwatertemperatureisintherangeof6～10℃innorthernareasinChina.ThereforetheseparameterscannotmeetthetreatmentsystemsinnorthernareasofChina,anditisdifficultfortheeffluentqualitytomeettheemissionrequirements.Hencetemperatureparametershouldbecombinedwithre
