波形潜流湿地处理低浓度生活污水＊曾祥英(,430074) 章北平 孙高升(,430074) 本文主要研究不同水力负荷条件下,波形潜流人工湿地对低浓度生活污水中有机物、氮和磷的去除效果及其影响因素。低、中、高水力负荷分别为0.2、0.4、0.8m3(m2·d),处理低浓度生活污水试验研究表明:水力负荷对CODCr和TP的去除率有一定的影响,都是随着水力负荷的增大而下降;对NH3-N和TN的去除效果几乎没有影响。 波形潜流湿地 生活污水 水力负荷 ＊“”“863”《》(2003AA601110)1 :,,-,,、、,,,、、,,,,。,,。1000mm,200mm,650mm(1)。,、,100、800mm100mm,580mm。,。:①,30～50mm;②600mm4,0～5mm150mm;5～10mm50mm;10～30mm200mm;30～50mm200mm;③。(。)2 ,、、0.2、0.4、0.8m3(m2·d),1 ,1。1 mgLCODCrTNTPNH3-N150～20020～301.5～2.015～202.1 CODCr的去除效果,CODCr2。2 、、CODCr2,CODCr,CODCr。,HRT,,、,。2.2 TP的去除效果,26 200610245DOI:10.13205/j.hjgc.2006.05.009TP3。3 、、TP3,TP,,0.2m3(m2·d)TP,31.7%,0.4m3(m2·d)TP,23.6%,0.8m3(m2·d)TP,15.3%。,TP,,:。、,,,。。DO0.1～0.4mgL,DO0.1mgL,2mgL。,,。2.3 氮的去除效果2.3.1 NH3-N,NH3-N4。4 、、NH3-N4,NH3-N,0.2m3(m2·d)0.4m3(m2·d)0.8m3(m2·d),、、3NH3-N15.9%、11.7%9.9%。NH3-N。,,,、、3,,NH3-N。:①pH:pH6.3～6.8,pH7.7,pH,。②:30%～50%,。③DO:,2～3mgL,,0.1～0.4mgL,。2.3.2 TN,TN5。5 、、TN5,TNNH3-N,TN,0.2m3(m2·d)0.4m3(m2·d)0.8m3(m2·d),、、3TN15.0%、9.48%9.45%。TN、,,。pH、、。①pH:,pH6.3～6.8,pH6.5～7.5,27 200610245pH。②:20～35℃,,12～18℃,。③:,,,,,。④DO:,,DO,。,,TN。,,,,,-TN。3 (1)CODCr,,HRT,,、,。(2)、、TP,,31.7%、23.6%、15.3%。TP,。 (3)、、NH3-N,15.9%、11.7%9.9%。NH3-N,pH、,,NH3-N。(4)TNNH3-N,、、3TN15.0%、9.48%9.45%。TN,,NH3-N。[1] ..,1995,(12).[2] RobertW.Dennis,RobertL.Irvine.Effectoffill:reactonsequencingbatchbiologicalreactors.JournalWPCF,1979,51(2):255-263.[3] ..,1999.[4] .、.,2000.[5] ,,,,..(),2005.6,().[6] MorganJM,ForsterCF.EvisonL.Acomparativestudyofthenatureofbiopolymersextractedfromanaeroticandactivetedsludges.WaterResearch,1990(6).[7] .SBR.:,2003. 430074 (027)61234541,62167008E-mail gibbon@163.com2005-11-30 ,,《》,200682～5“2006()”。,,“”。、、、,,,。、,。,、、,。,,。,,,。,,,。,,。28 200610245Abstract Characteristicsofanaerobic-aerobicbiologicalfilter(AABF)werestudiedtotreatmunicipalwastewaterinapilotscaleexperiment.TheexperimentalresultsshowedthatAABFhadhighefficienciestoremoveorganicpollutants,suchasCODCr,SSandNH+4-Ninmunicipalwatewater.TheremovelratesofCODCr,SSandNH+4-Nareover90%,80%and75%respectively,wheninfluentCODCr,SSandNH+4-Nare234mgL,112mgLand56mgL,hydraulicretentiontimeis8h,andaeratedintensityisintherangeof0.5～0.6L(m2·s).Keywords anaerobic-aerobicbiologicalfilter(AABF),municipalwastewaterandbio-filmUSINGCORRUGATEDUNDERFLOWWETLANDTOTREATLOWCONCENTRATIONDOMESTICWASTEWATERZengXiangying ZhangBeiping SunGaosheng(26)…………………………………Abstract Itwasstudiedtheremovaleffectoforganisms,NandPindomesticwastewaterbyacorrugatedunderflowwetlandsubjectedtodifferenthydraulicloadings.Thelow,mediumandhighhydraulicloadingswere0.2m3(m2·d),0.4m3(m2·d)and0.8m3(m2·d)respectively.TheresultsshowedthathydraulicloadinghadacertaineffectontheremovalrateofCODCrandTP,i.e.theremovalratewasdecreasedwithincreaseinhydraulicloading;italmosthadnoeffectontheremovalrateofNH3-NandTN.Keywords corrugatedunderflowwetland,domesticsewageandhydraulicloadingTHEFEASIBILITYSTUDYOFELECTRO-COAGULATIONMETHODFORPRETREATINGLEACHATEYangJidong ZhaoYongsheng ZhaoXiaobo(29)……………………………………………………………Abstract Astudyofpretreatmentofleachatebyelectro-coagulationmethodwascarriedout.UsingFeanodeandstainlesssteelcathode,electrodespacingwas1.5cm,currentintensitywas50mAcm2andelectrolytictimewas90minuteswithoutaddingelectrolyte.TheremovalratesofCODCrandNH+4reached57.6%and40.1%respectively,theBOD5CODCrratiowasimprovedfrom0.15to0.32.Sothismethodreachedagoodpretreatmenteffect.Keywords leachate,pretreat,eletro-coagulationandbiochemicaldegradabilityTREATMENTOFDOMESTICWASTEWATERREUSEANDCLEANINGOFMEMBRANTBYSMBRDongLijing XuGaotian TangFanmin(31)…………………………………………………………………………Abstract CASS(cyclicactivatedsludgesystem)processandmembranefiltrationwerecombinedtobeaSMBR(submergedmembranebioreactor).ThestudywasonfeasibilityofthisSMBRusedinreclamationofdomesticwastewater.ThefittingoperationconditionwasdeterminedasHRT=4h,dissolvedoxygen(DO)about4mgL,temperaturewascontrolledat23～27℃,pH=6.5～8.0.Undertheconditions,disposalimpactstoactualdomesticwastewaterwerestudied.Atthesametime,themethodofthemembranecleaningwasalsostudied.Keywords SMBR,ultrafiltrationmembraneandcleaningofmembraneANALYSISOFPARAMETEROFPLASMADESULFURIZINGTECHNOLOGYYiChengwu LuCongxiang XuWeietal(34)…………………………………………………………………………………………………………Abstract SO2isremovedfromthesimulatedgasstreamsusingnon-thermalplasmawhichcanbeformedbythestrongionizationdischargeofdielectricbarrier.Theinfluenceofthesefactorsondesulfurizationratewasanalyzed.Themultiplelinearregressionmodelwasfoundedandthesignificanceleveloftheseinfluencevariableswasanalyzedbythemethodofsimpleregressionorthogonaldesign,thequantitativeruleofexperimenttargetandsinglevariableisconcluded.itwasalsofoundouttheconditionassociationoftheoptimumexperimentconditionsbyoptimizationofthemodel.Keywords non-thermalplasma,dielectricbarrierdischarge,simpleregressionorthogonaldesignanddesulfurizationDEDUSTINGREFORMOFSINTERINGMACHINEFORCHUXIONGDESHENGIRONANDSTEELCOMPANYYangLifang ZhangZhiling XuXiaojun(38)………………………………………………………Abstract Itisintroducedsometechnicalanddesignproblemsofthree-electrodeselectrostaticdustcatchers,whichh
