大型纺织染整企业综合废水处理工程设计李方

李　方　杨　波　田　晴　陈季华(,200051)　针对纺织染整企业各股废水的特点,提出混凝沉淀+生化处理的工艺路线,并考虑在工艺系统中实现污泥减量。工程运行结果表明,出水水质优于《纺织染整工业水污染物排放标准》(GB4287-92)中一级排放标准,实现部分污水回用,而且系统污泥减量效果良好。　纺织　染整　综合废水　污泥减量　　、、、、。,,。1　、1.1　设计水量Q=15000m3d,、、。1.2　设计水质分析,,41。1　COD(mg·L-1)BOD5(mg·L-1)pHSS(mg·L-1)NH3-N(mg·L-1)(m3·d-1)10003501286～720010300030001200646～6.52002040025004005129～114001090006002002568～111200520004001506.5～7.54004060015005004008.5～1135015150001.2.1　、,Ⅰ、Ⅱ、Ⅲ,CODBOD5,COD3.2mgL。90%,3000mgL,BOD51500mgL[1]。COD,,[2]。1.2.2　、。CODpH,PVA[3]。COD2000mgL,。COD200～400mgL,,pH11。,9000m3d,pH,COD、,pH,。1.2.3　,、、、、,COD600mgL。。,《》(GB4287-92)。2　1。77　　　200810265DOI:10.13205/j.hjgc.2008.05.0231　　　,,pH,,PVA、、。,PVA、、、,,,BC。,,。(),0.5mgL,,。,。,,,[4-5]。,,。,,。,,。3　,。。2。2　()42m×32m×5.3m1HF-800,210m×6m1200-WLB360-7.4-15,332m×12m×5.3m142m×32m×5.5m2TA42m×32m×5.3m1TA42m×20m×5.3m2JAS-200,4,,HA-65=24m,h=5.5m2BXH-24,25m×5m×3.3m16m×6m112m×8m1=24m,h=5.5m2BXH-24,215m×10m×5.5m2JTS-80,1;=10m,h=5.5m219m×9.5m1CDYC150020m×8m110m×10m1200WLB360-7.4-15,318m×8m()178　　　2008102654　(1),、(),C∶N∶P=100∶5∶1(,C∶N∶P),;7d,。30d,、,3000mgL,。4d,,《》(GB4287-92),3。3　mgL(pH、)CODBOD5SSNH3-NpH90154076～730　　,、,,。(2),。:①“++”,,;②,、PVA,。5　(1),“++”,。(2)“++”,,。[1]　,,..:,1990:135-167[2]　,..,2001,19(6):7-9[3]　.PVA.(),2002,28(1):101-104[4]　,,,.-A1A2O.,2006,27(3):478-482[5]　,,,.-A1A2O.,2007,28(6):1280-1284　　201620　2999E-mail　[e-mail]2008-02-132008《》《》()1982,,,。、。:、、、、、、、、、。,、、、、、。《》,CN53-1205x,ISSN1673-9655,25,96,60,。　　　　　　　　　　　　　　　　　　:650034::23::《》　　:53001615637050309169():0871-4142389E-mail:[e-mail]。79　　　200810265APPLICATIONOFMBRTECHNOLOGYINTREATMENTOFPCB'sWASTEWATERWuShiwen(68)…………………………………………………………………………………………………………………………………Abstract　ThepracticalapplicationofMBRtechnologyintreatmentofPCB'swastewaterwasintroduced.TheoperationresultsshowthattheMBRsystemisstablewithqualityeffluentunderthefollowingconditions:theinfluentCODof1500mgL,Cu2+of1.5mgL,MLSSof6000～8000mgLandDOof2～4mgL,withthesystemtemperatureof20～40℃,residencetimeof10handaerationquantityof40～43m3min.TheaverageremovalrateofCODisover87%andthatofCu2+isabout70%.Keywords　MBRtechnology　PCB　COD　Cu2+　treatmentofwastewaterENGINEERINGPRACTICEANDSTUDIESONSLAUGHERWASTEWATERTREATMENTGuoTing　YangPing　WangHonglei(70)………………………………………………………………………………………Abstract　Theslaugherwastewaterwastreatedwithhydrolyticacidification-CASStechnology.TheoperationalresultsprovethattheCASStechnologyhasgoodeffectiveness.VariousfoulingindexesoftheeffluentmeetthefirstclassofDischargeStandardofWaterPollutantsofMeatPackingIndustry(GB13457-92).Keywords　slaugherhousewastewatertreatment　hydrolyticacidification　CASSPRETREATMENTOFREFUSELEACHATEBYCOOPERATIONFUNCTIONOFHIGHMAGNET-ICPOWDERTangYanchao　ChengYue　FuMingliang(72)……………………………………………………………Abstract　Thecooperationfunctionofhighmagneticpowder(Fe3O4)andabio-coagulantAl2(SO4)3werestudiedinthispaper.TheresultindicatedthattheflocculationeffectfromcomplexuseofFe3O4andAl2(SO4)3wasbetterthanuseofAl2(SO4)3only.WhendosageofAl2(SO4)3is2.0gL,Fe3O4is1.6gL,stirringrateis150rpm,pHis3.0,sedimentationtimeis5min,theCODremovalrateofleachateis70%.Thesedimentationvelocityofcolloidalparticleispickedupevidentlyinflocculation.Keywords　highmagneticpowder　cooperationfunction　leachate　flocculationRESEARCHONMAINFACTORSOFINFLUENCINGBIOLOGICALP-PEMOVALINEBPRSYS-TEMCaiTianming　CaiShu　NingQiangetal(74)…………………………………………………………………………Abstract　Takingenhancedbiologicalphosphrousremoval(EBPR)systemastheobjectofstudy,itwasresearchedtheeffectsofinfluent'sacetateconcentration&pHandresidenttimeofsludgeonitsphosphorusremoval(PR).TestresultsshowedthatPRratewasincreasedgradual-lywiththeincreaseofacetateconcentrationwhenaceticacidwaslessthan30%beforekeepinganaerobicconditionfor45min;afterkeepinganaerobicconditionfor2h,theconcentrationofaceticacidhaslesseffectonPR.ThesuitablepHwas6.0～7.0foranaerobicPR,aerobicobso-rptionofphosphorusandCODdegradation.WhenpHwaslargerthan8.0thesystemwouldloseEBPRcapacityandPRwasonly39.7%.Iftheagewas4dtheconcentrationofPintheeffluentwaslowerandthesystemwouldhavethebestrunningeffect.Keywords　EBPR　acetateconcentration　pH　sludgeageDESIGNOFCOMPOSITIVEWASTEWATERTREATMENTPLANTOFALARGETEXTILECOR-PORATIONLiFang　YangBo　TianQinetal(77)………………………………………………………………………Abstract　Accordingtothecharacteristicsofthecompositivewastewaterinalargetextilecorporation,theprocessofcoagulatingsedimenta-tionandbiologicaltreatmentwasadoptedinthisproject.Thesludgereductiontechniquewastakenintoaccountinthisdesign.ThepracticeshowedthattheeffluentqualitymettherequirementofGradeⅠof“NationalTextileWastewaterDischargeStandard”(GB4287-92)andpartofbio-filtereffluentwasreclaimed.Theexcellentbiologicalsludgereductionwasobtainedduringtherun.Keywords　textile　dyingandfinishing　compositivewastewater　sludgereductionAUNIVERSALEXPONENTIALFORMULAOFAIRQUALITYASSESSMENTBASEDONARTIFI-CIALFISHSWARMALGORITHMLiZuoyong　WangJiayang　WuMin(80)……………………………………Abstract　Bysettingupbenchmarksforairqualityindices,auniversalexponentialformulawithpowerfunctionformulti-indicesofairpol-lutantisputforthforevaluatingairquality.Artifi
