IC王哲,胡凤燕,路忻,刘从彬,穗贤杰,李永焱 (,450004) 利用IC反应器处理垃圾渗滤液,试验在判断渗滤液C/N性能的基础上逐步提升进水有机负荷,使进水负荷在反应器启动末期达到垃圾渗滤液原水水质的要求,随着颗粒污泥的形成,反应器出水C/N比由0.62提高到1.70,CODCr去除率达到56.8%,氨氮去除率达到12.5%。反应器对垃圾渗滤液的去除率较低,建议实际工程中后续深度处理工艺。 垃圾渗滤液;颗粒污泥;有机负荷;厌氧;去除率 X703   A   0517-6611(2010)26-14596-02ResearchonLandfillLeachateWastewaterTreatmentinICReactorWANGZheetal (HenanProvinceResearchInstituteofEnvironmentalProtectionScience,Zhengzhou,Henan450004)Abstract IntheuseofICreactortreatmentoflandfillleachate,onthebasisofdeterminingtheC/N,increasedgraduallyinfluentorganicload,organicloadreachthequalitiesofrawwaterinthelatestartingofreactor,withtheformationofgranularsludge,C/Nfromthe0.62ratioincreasedto1.70ofreactoreffluent,CODcrremovalratereached56.8%,ammoniaremovalratereached12.5%.Reactorontheremovalrateoflandfillleachateislower,itwasproposedthattheadvancedtreatmentprocessfollow-upICreactorintheactuallyworks.Keywords Landfillleachate;Granularsludge;Organicloading;Anaerobic;Removalrate 王哲(1982-),男,河南南阳人,硕士,从事水环境研究。 2010-06-07  ,[1]。,。IC,,。1 1.1  IC,,4800mg/L,SVI245ml/g。20h,IC。。,CODCr。,CoNi[2]。,24h,。:CODCr4225.1mg/L,BOD51521.4mg/L,SS713.5mg/L,1052.3mg/L,pH5.3。1.2  IC,,13.2cm,0.5cm,129.0cm,101.0cm,46.0cm,20.0cm×20.0cm,,,15.0mm,14.1L,13.8L,7。1。1.3  CODCr;NH3-N-;pHPHS-3C;;SS103~105℃。2 2.1  BOD5:1.;2.;3.;4.;5.;6.;7.IC;1#~7#:。Note:1.Inletchest;2.Peristalticpump;3.Drainagetank;4.Intakepipe;5.Inletpipe;6.Airflowmeter;7.ICreactor;1#-7#.samplecollectingmouth.1 ICFig.1 TestflowofICreactorBOD5/CODCr[3],,IC,1∶1,。25℃,8h1CODCr,3d。2。  2,3,CODCr,75.6%,,,1617.8mg/L。CODCr0.62,。,。2.2  3,CODCr1384.5mg/L,5,1730.6、2163.3、2704.1、3380.1、4225.2mg/L。CODCr,CODCr56.8%。CODCr 李菲菲  卢瑶,JournalofAnhuiAgri.Sci.2010,38(26):14596-145972 CODCrNH3-NFig.2 CurveofCODCrandNH3-Nremovalrateinthebiochem-icaltext,CODCr。、。CODCr1825.2mg/L。3 CODCrCODCrFig.3 CurveofconcertrationofinfluentCODCrandeffluentCODCrremovalrate  4,344.8mg/L,5,25%,920.8mg/L,12.5%,。,。4 Fig.4 CurveofconcertrationofinfluentNH3-NandeffluentNH3-Nremovalrate2.3 (HRT)CODCr、 ,HRTCODCr、。5,HRT5.5hCODCr,60%,HRT,CODCr,HRT7.0h56.6%。1,HRT,,HRT5.0h,HRT6.5h,。,,ICHRT5.5h,CODCr、,C/N1.70,C/N。5 CODCr(HRT)Fig.5 CurveofCODCrremovalrateandHRT1 (HRT)Table1 TherelationshipbetweenNH3-NremovalrateandHRTSamplenumber∥hHydraulicretentiontimeNH3-N∥mg/LInfluentammoniaNH3-N∥mg/LEffluentammonia∥%Removalrate15.01052.3917.612.825.51052.3992.35.736.01052.31028.12.346.51052.31084.9-3.157.01052.31132.3-7.63 ,,0.62。5,,CODCr、,,CODCr56.8%,12.5%,。,HRT5.5h,C/N1.70,C/N。[1]肖可青.垃圾填埋场渗滤液处理技术及其应用[J].环境工程,2009,27(S1):181-184.[2]柳燕,管慧玲,刘精今,等.厌氧污泥颗粒化的影响因素[J].中国沼气,2006,24(2):11-14.[3]李平,韦朝海,吴超飞,等.厌氧/好氧生物流化床耦合处理垃圾渗滤液的新工艺研究[J].高校化学工程学报,2002,16(3):345-350.1459738卷26期                王哲等 IC反应器处理垃圾渗滤液的特性研究
