201028*籍国东 周 游( , 100871) :研究了水力停留时间对垂直流人工湿地处理不同碳氮比稠油废水的影响,考察了垂直流人工湿地处理高盐、含烃难降解有机废水的性能。结果表明:在适宜的水力停留时间和COD/TN/TP比的情况下,间歇运行的垂直流人工湿地的净化能力与COD/NH3-N相关,在COD/NH3-N为20和13.4的情况下,垂直流人工湿地具有很好的碳氮磷去除能力;当COD/NH3-N为40或6.7的情况下,垂直流人工湿地的净化能力受到抑制。:垂直流人工湿地;碳氮比;稠油废水;水力停留时间STUDYONTREATMENTOFVISCOUSOILWASTEWATERWITHDIFFERENTC/NRATIONSBYVERTICALFLOWCONSTRUCTEDWETLANDJiGuodong ZhouYou(TheKeyLaboratoryofWaterandSedimentSciences,MinistryofEducation,DepartmentofEnvironmentalEngineering,PekingUniversity,Beijing 100871,China)Abstract:ThisarticlemainlystudiestheimpactofHRTonverticalflowconstructedwetlandintreatingdiffer-entC/Nratioviscousoilwastewater,andinvestigatestheperformanceofverticalflowconstructedwetlandintreatinghyper-salineandrefractoryhydrocarbon-bearingorganicwastewater.Theresultsshowthatthere-movalabilityofintermittentrunningverticalflowconstructedwetlandiscorrelatedwithCOD/NH3-NintheconditionofappropriateHRTandCOD/TN/TPratio.TheverticalflowconstructedwetlandshowsgoodC,N,PremovalabilitywhenCOD/NH3-Nratiois20or13.4andshowsinhibitedwhenCOD/NH3-Nratiois40or6.7.Keywords:verticalflowconstructedwetland;C/Nratio;viscousoilwastewater;HRT*(40772146);;。0 ——、,、、、、,,,[1-3]。、、、、、[4-5]。,[6-8]。,2090、,,[9]。,,。1 1.1 垂直流人工湿地系统设计:L=900mm,M=333mm,H=600mm,PVC,PVC,。3,0~150mm3~5mm,150~400mm5~20mm,400~600mm20~50mm。1.2 人工湿地进水水质A、B、C、D4,NH4Cl、KNO3、KH2PO4、K2HPO4COD/TN/TP150DOI:10.13205/j.hjgc.2010.s1.044 201028,A、BCOD/TN/TP100∶20∶1,C、DCOD/TN/TP100∶10∶1。1。1 mg/LABCDpH7.427.427.427.42COD213213213213Oil96.596.596.596.5Cl-1372137213721372COD/TN551010COD/TP100100100100COD/NH3-N206.74013.4NH3-N/NO3-N1/33/11/33/11.3 分析方法pHpH-25,COD,BOD5,,Oil,NH3-N,TN,TP。2 2.1 不同水力停留时间氮磷的变化1,A、B2TNTP,TNTP,ATN,BTN。:A、B2TNNO3--NNH3-N,ANH3-NB1/3,NO3--NB3。BNH3-NA3,NO3--NA1/3。ATNNO3--N,NO3--NN2,NO2--N。BTNNH3-N,NH3-NH2O、CO2、NO3--N,NO3--N。2,BTNNH3-N,COD/NH3-N6.7,NH3-N。C、DTNTP,96h,TNA、B。2,NH3-N48h,TN72h96h。CDTNNO3--NNH3-N,DNH3-NC3,NO3--NC1/3。DTNNH3-N,,NH3-NH2O、CO2、NO3--N,NO3--NN2。CTN48h,NH3-NNO3--N,NH3-N,NO3--N。1,A、DTPB、C,96hA、D。:96h,,TP,。1 TNTP2.2 不同水力停留时间Oil的变化3,Oil96.5mg/L,24h,Oil10mg/L,48h0.5mg/L,96h99.6%。2.3 不同水力停留时间Cl-和盐的变化4,Cl-.4,A、B、C、D4Cl-96h,1600mg/L。,,Cl-。2.4 不同水力停留时间COD的变化5,96h,A、DCOD75%79%;B、CCOD59%65%。151 2010282 TN、NH3-NNO3--N3 Oil4 Cl-A、BCOD/TN100∶20,100∶10。2COD/TN/TP,96hCOD16%。2COD/NH3-N,206.7。ACODCOD/NH3-N,COD/NH3-N20(100∶5),,48h,96h,COD,75%。BCOD/NH3-N6.7(100∶15),,COD/NH3-N,24h,COD/NH3-N,,COD,COD59%。5 CODC、D2COD/TN/TP100∶10∶1,COD14%,:2COD/TN/TP,COD/NH3-N,4013.4。,C96hCODCOD/NH3-N,COD/NH3-N40,,COD,COD65%;DCOD/NH3-N13.4,,24h,COD/NH3-N48h,96h,COD45mg/L,COD79%。3 COD/TN/TP,COD、Oil、TN、TPNH3-NCOD/NH3-N,(186)152 201028 :“”(、)();“”;“”、。“”。,。“”、、(),;“”;“”,,。3.2 结果分析,PM10,29.4%,(、、),20.0%。SO2,13.28%,39.0%,。,SO28,2;PM10,6,4。4 ADMS-Urban,,。[1](CERC).ADMS-Urbantechnicalspecification[M].Cambridge,2001.[2],.ADMS-Urban[J].,2004,30(121):4-6.[3].ADMSSO2[J].,2004,29(3):54-56.[4].ADMSTSP[J].,2003,23(4):19-21.[5].HJ2.2-2008[S].:2009.[6],ADMS-Urban[J].,2004,(5):26-32. 100840 27307E-mail lizhuor@126.com2010-01-07(152)COD/NH3-N2013.4,;COD/NH3-N406.7,COD、Oil、TN、TPNH3-N。[1],,,.[J].,2008,26(6):42-44.[2],,.[J].,2003,4(2):36-40.[3],,,.[J].,2004,23(1):22-29.[4],,,.[J].,2006,25(5):1318-1323.[5],,.[J].,2002,13(2):224-228.[6],.[J].,2001,21(5):619-621.[7],,,.[J].,2001,22(4):95-99.[8],,.[J].,2008,26(1):32-34.[9]JiGD,SunTH,NiJR.Surfaceflowconstructedwetlandforheavyoil-producedwatertreatment[J].BioresourceTechnology,2007,98(2):436-441. 100871 (010)62755914-87E-mail jiguodong@iee.pku.edu.cn2010-05-07186
