寡毛类蠕虫污泥减量技术的稳定性研究进展白润英

　　　201129寡毛类蠕虫污泥减量技术的稳定性研究进展＊白润英　宋　蕾　宋虹苇(,　010051)　:对近年来国内外寡毛类蠕虫污泥减量技术的稳定性研究进展进行了系统评述。除了选择适合稳定减量的蠕虫种属以外,蠕虫反应器构造和废水处理工艺流程、污泥减量工艺的运行操作参数、以及活性污泥本身,都是影响寡毛类蠕虫在活性污泥系统中稳定存在并直接影响到其对活性污泥的捕食和削减能力的重要因素。通过对现有研究进行分析,指出寡毛类蠕虫污泥减量工艺投入实际工程应用的技术和经济瓶颈。:活性污泥法;污泥减量稳定性;寡毛类蠕虫ADVANCESINSTABILITYOFSLUDGEREDUCTIONINDUCEDBYOLIGOCHAETESBaiRunying　SongLei　SongHongwei(DepartmentofMunicipalEngineering,SchoolofCivilEngineering,InnerMongoliaUniversityofTechnology,Hohhot010051,China)Abstract:Advancesinstabilityofsludgereductioninducedbyoligochaetesarethoroughlyreviewed.Exceptforoligochaetes'sdifferentspecies,wormreactorsstructureandactivatedsludgeprocess,operationparame-ters,activatedsludgeitself,bothsignificantlyinfluencedoligochaetes'sstablepresenceandpredationinsludgeandtheircapacityofsludgereduction.So,therearealsotechnicalandeconomicconstraintsinpracticalapplica-tionofsludgereductioninducedbyoligochaetes,whichwasreachedbyanalyzingtheexistingresearchresults.Keywords:activatedsludgeprocess;stabilityofsludgereduction;oligochaetes＊(2010MS0603);(NJ10084)。0　,,。、50%～60%[1]。,、[1-2]。:,;,,。、。,,。,。,:,,,;,,()。、,[3-6]。,,、、。1　、[7]。,。(Annelida)(Oligochaeta),,,。,,,(A.hemprichi)(Naissp.);,(Tubificidae)、(Lumbriculidae)(Earthworm)[8-11]。,,,193DOI:10.13205/j.hjgc.2011.s1.091　　　201129[1,12]。(Tubificidae)、(Lumbriculussp.)(Earthworm)。,。1.1　颤蚓(Tubifex),,,(Tubifici-dae),,2.5～4cm,0.7～0.8mm,,。。,、、、、、。8～9,、,、,,,[13]。(),(Limnodrilushoffmeisteri)、(Branchiurasowerbyi)(TubifextubifexMǜller),。3、。1.2　夹杂带丝蚓(LumbriculusVariegatus),,,(Lumbriculidae),L.variega-tus。L.variegatus,[8]。,、、、、。,。L.vaiegatus,4～6cm(17cm),1.5mm,,。(),L.variegatus[14]。L.variegatusTubifex[8],L.variegatusTubifex,L.variegatus、Tubifex,L.variegatus。1.3　蚯蚓(earthworm),,,(Lumbricus),。3000,200,20,1～210[15]。,,,40～150mm、3～5mm。,。LiminZhao[16],(VSS)56.2%～66.6%,25.1%,:,100～200μm0～2μm,,,。[17],,30d2,26.67%27.14%,23.56%24.81%,。2　,,。,。2.1　废水处理工艺流程,,,,。,,(CAS),,,。CAS[18-21,24-25],。2.2　蠕虫反应器:,;。194　　　2011292.2.1　Wei[18],,(1～2mm,0.9～0.92g/cm390%～95%),,,1。,,48%。,。。,,,,。,Wei[19](IODVC)—,,,2。(80%,2cm),(1COD0.33kg),(SVI78mL/g),IODVC,。1　、,Guo[20]、6cm8cm33(0.28m、0.03m、0.03m),235d。,46.4%,COD0.0619g。(、)。[21],5mm12　(IODCXVC)-mm,,,44%33%。,。,,。、,,。,T.L.G.Hendrickx[22]—(TSS)g/(m2·d),。L.variegatus,。300μm350μmL.variegatus0.871.1kg/m3,TSS45,58g/(m2·d)。,350μm29%。,[11]38.20%48.20%,,。,、、[18-19,21]。,HellenJ.H.Elissen[23](300μm),3,L.variegatus。L.variegatus,、。195　　　201129,,,(),。。,49mg/d,25%,75%(2%,73%)。0.045mg/(mg·d),4.5%。,。3　,T.L.G.Hendrickx[24]300μm350μmL.variegatus。50d,,300μmL.variegatus,350μm0.013d-1。L.variegatus,T.L.G.Hendrickx[25]350μm,,8,0.014d-1,0.009～0.013d-1。,,、,。2.2.2　YuTian[26],(FHIA)(DO)。(SS-BWR):、、(100L)。SSBWR、,。4SSBWR:(0.01～0.05m3/h)—;,(0.2～0.35m3/h)—,5min。,。FHIA,VSS(A■VSS)480mg/(L·d);FHIA,VSS,,,,A■VSS。FHIA,FHIA12/d,;DO2mg/L(0.24kg/m2),DO,DO,,DO,DO1mg/LA■VSS470mg/(L·d),DO1～1.6mg/L。4　(SSBWR)4.5mg/L36.5mg/L,T.L.G.Hendrickx[27]1mg(TSS)0.02mg,,5%～196　　　20112915%(pH7.3～7.8)、5%。,。,Yutian[28]76dSSBWR,,33.6%,、(NH4+-N)67.5%、98.5%63.0%,COD,COD72.5%。3　T.L.G.Hendrickx(DO)、L.variegatus[27]。,DO1mg/L～2.5mg/L,;,15℃,10℃(TSS);L.variegatus,L.variegatus。,,,15%～20%,5%。[29]t50。,,(SV,30min)t50,TSSSVI。SVTSSSVI,t50,,SV。,,,,。,,1h,,8%～42%[30]。Huang[31],100%,(2.5g/L),0.18～0.81kg/(kg·d)。Yutian[26](ISC)、(SRT),VSS(480mg/(L·d)),ISC3000～4000mg/L、SRT2d。[11]、(),23～28℃,,;,。[32]15～24℃18～26℃,38.2%～44.7%40.5%～48.2%,4.8～5.5m3/(m2·d)。4　4.1　不同污泥营养价值的影响Finogenova[33],,2,。T.L.G.Hendrickx[24]L.variegatus,,TSS16%～26%,75%36%[23,27],,L.variegatus。,L.variegatus,。4.2　污泥中未知组分的影响。T.L.G.Hendrickx[22],,。ElissenH.J.H[8]L.variegatus(),、。,L.variegatus()();,L.varie-gatus。2,、、、W/S(/,)、pH。,,、[34]。,,197　　　201129,,[8]。4.3　不同污泥浓度(TSS)的影响[30]TSS4.39g/L、5.99g/L7.72g/L,1h,8%～42%。,,(1～3h)、Zeta,(SVI)。,,,,,SVI,。Huang[31],(TSS3.3g/L),SVI。[27]Pearson,TSSSVI,(SV,30min)t50。4.4　污泥中有毒物质的影响[35],、、。,,—,,,,。。HuangX[31]、2.5,880,5100mg/L。,[17]Cu、Zn、Pb、Cr,,。ZnCu[36],,ZnCu;,PbCr,,[38]。T.L.G.Hendrickx[28](NH3),。—(chitosan)[38]。5　,,,,。。,。:,;,,、;;()、,;(、),。:、、,;,,,,。[1]WeiYS,vanHoutenRT,BorgerAR,etal.Comparisonperform-ancesofmembranebioreactor(MBR)andconventionaactivatedsludge(CAS)processesonsludgereductioninducedbyoligochaete[J].EnvironSciTechnol,2003,37(14):3171-3180.[2],,,.[J].,2003,4(1):44-52.[3]LiangP,HuangX,QianY,etal.Comparisonofsludgereductionratescausedbythefourmicro-fauna'spredation[J].BioresourceTechnology,2006,97(6):854-861.[4]LiangP,HuangX,QianY.ExcesssludgereductioninactivatedsludgeprocessthroughpredationofA.hemprichi[J].BiochemicalEngineeringJournal,2006,28(2):117-122.[5]ChenGH,Kyoung-JinA,SwvastienS,etal.Possiblecauseofex-cesssludgereductioninanoxic-settling-anaerobicactivatedsludgeprocess(OSAprocess)[J].WaterResearch,2003(37):3855-3866.[6]WeiYS,LiuJX.ThedischargedexcesssludgetreatedbyOli-gochaeta[J].WaterScienceandTechnology,2005,52(10/11):265-272.198　　　201129[7],,.[J].,2005,31(7):19-22.[8]ElissenHJH.SludgereductionbyaquaticwormsinwastewatertreatmentwithemphasisonthepotentialapplicationofLumbriculusvariegatus[D].theNetherlands:WageningenUniversity,2007.[9].[D].:,2004.[10].[D].:,2007.[11],,.[J]
