表流人工湿地改善玉清湖入库水水质的研究修春海

修春海1,　焦盈盈2,　武道吉2(1.哈尔滨工业大学市政环境工程学院,黑龙江哈尔滨150090;2.山东建筑大学市政与环境工程学院,山东济南250101)　　　:　在济南玉清湖水库的进水口附近构建了芦苇床表流人工湿地和蒲草床表流人工湿地,考察了对入库微污染黄河原水水质的改善效果。结果表明:两个人工湿地对COD的平均去除率均低于10%,对总氮的平均去除率分别为56.17%和69.44%,对总磷的去除效果极不稳定。随着气温的降低,两个人工湿地的处理效果逐渐变差。与夏季相比,冬季对总氮的去除率降低了约50%。蒲草床表流人工湿地对总氮和硝态氮的去除效果明显好于芦苇床表流人工湿地,这与蒲草长势好、种植密度大有关。　　:　黄河水;　人工湿地;　水质改善:TU991　　:C　　:1000-4602(2008)13-0100-04Surface-flowConstructedWetlandforImprovementofWaterQualityintoYuqingLakeReservoirXIUChun-hai1,　JIAOYing-ying2,　WUDao-ji2(1.SchoolofMunicipalandEnvironmentalEngineering,HarbinInstituteofTechnology,Harbin150090,China;2.SchoolofMunicipalandEnvironmentalEngineering,ShandongJianzhuUniversity,Jinan250101,China)　　Abstract:　Surface-flowconstructedwetlandswithreedandcattailrespectivelywereconstructedattheentranceofYuqingLakeReservoir.Theeffectimprovingqualityofthemicro-pollutedYellowRiverrawwaterintothereservoirwasinvestigated.TheresultsindicatethattheaverageremovalratesofCODinthetwodifferentwetlandsarebothbelow10%,andTNremovalratesare56.17%and69.44%re-spectively.TheremovalefficienciesofTPareunstable.Withthedecreaseofthetemperature,theremov-alefficiencyinthetwowetlandsdecreasesobviously.TheremovalrateofTNinwinterdecreasesby50%comparedwiththatinsummer.Thesurface-flowconstructedwetlandwithcattailhasbetterremovaleffi-ciencyofTNandnitratenitrogenthansurface-flowconstructedwetlandwithreed,whichowestogoodgrowthandhighdensityofcattail.　　Keywords:　YellowRiverwater;　constructedwetland;　waterqualityimprovement　　———2000,。,,,,。、,、、[1～5]。。,。·100·24　1320087　　　　　　　　　　　　CHINAWATERWASTEWATER　　　　　　　　　　　　　Vol.24No.13Jul.20081　试验材料与方法1.1　1。1　Fig.1　Flowchartofconstructedwetlands。16m×5.70m,0.15m;16m×5.70m,0.15m。20056,、、,100L/h,6d,4m/d。1.2　,4～5/。COD:;:;pH:;TN:;TP:;NH+4-N:;NO-3-N:;NO-2-N:。2　结果与分析2.1　COD,COD10%,:①;②,,[6],COD。2.2　2.2.1　TN2。2　Fig.2　ComparisonofTNremovalbydifferentwetlands2,。、,1mg/L。,,、,[7];,,,。、,,,,。、,[8]。,,,,,。2.2.2　、、TN、NH+4-N、NO-3-N、NO-2-N1。1　、Tab.1　Compositionofnitrogenfrominfluentandeffluentmg·L-1　TNNH+4-NNO-3-NNO-2-N3.240.542.670.0301.420.500.900.0130.990.480.500.005　　1,NO-3-N。,NH+4-N,NO-3-N·101·:24　13[9]。,、,,[10、11],NH+4-N,、。,、NO-2-N。2.3　TPTP3。3　Fig.3　ComparisonofTPremovalbydifferentwetlands、、3[12],ATP,。,,。,TP,,TP。,,,[13]。3,,。50%,,。,,,,TP。,,,,。,0.06mg/L,,TP。3　结论①　COD10%,56.17%69.44%,。②　,。、,50%。③　,。:[1]　AllenWC,HookPC,BiedermanJA,etal.Tempera-tureandwetlandplantspecieseffectsonwastewaterandrootzoneoxidation[J].JEnvironQual,2002,31:1010-1016.[2]　JiGD,SunTH,ZhouQX,etal.Constructedsubsur-faceflowwetlandfortreatingheavyoil-producedwateroftheLiaoheOilfieldinChina[J].EcolEng,2002,18(4):459-465.[3]　ScholesL,ShutesRBE,RevittDM,etal.Thetreat-mentofmetalsinurbanrunoffbyconstructedwetlands[J].SciTotalEnviron,1998,214(1):211-219.[4]　KlrnJ,IdlerC.Treatmentofdomesticandagriculturalwastewaterbyreedbedsystems[J].EcolEng,1999,12(1-2):13-25.[5]　SakadevanK,BovarHJ.Nutrientremovalmechanismsinconstructedwetlandsandsustainablewatermanage-ment[J].WaterSciTechnol,1999,40(2):121-128.[6]　.[J].,2000,16(2):1-6.(下转第105页)·102·24　13　　　　　　　　　　　　　　　　　　　　　　　　　　。:,,。,F2,,,,,F2。,,,,,,,,,。,,。3　结论①　,,F2。②　,,TOC0.456mg/L15.51mg/L,TN4.347mg/L6.388mg/L(100),;,TOC6.881mg/L,TN2.765mg/L,,。③　,,。,。致谢:特别感谢朋友吴波的精心指导和帮助。:[1]　,,,.[J].,2003,19(4):1-4.[2]　.[J].,1996,19(3):59-62.[3]AliyuM,HepherMJ.Effectsofultrasoundenergyondegradationofcellulosematerial[J].UltrasonSonochem,2000,(7):265-268.:[phone]　15900745070E-mail:[e-mail]:2008-01-29(上接第102页)[7]　JobGD,BiddlestoneAJ,GrayKR.Treatmentofhighstrengthagriculturalandindustrialeffluentsusingreedbedtreatmentsystems[J].ChemEngResDes,1991,69(3):187-189.[8]　,,.[J].,2002,13(2):224-228.[9]　,,,.[J].,2007,23(21):49-52.[10]　SartorisJJ,ThullenJS,BarberLB,etal.InvestigationofnitrogentransformationsinasouthernCaliforniacon-structedwastewatertreatmentwetland[J].EcolEng,2000,14(1-2):49-65.[11]　CominFA,RomeroJA,AstorgaV,etal.Nitrogenre-movalandcyclinginrestoredwetlandusedasfiltersofnutrientsforagriculturalrunoff[J].WaterSciTechnol,1997,35(5):255-261.[12]　ZhuTong,SikoraFJ.Ammoniumandnitrateremovalinvegetatedandunvegetatedgravelbedmicrocosmwet-lands[J].WaterSciTechnol,1995,32(3):219-228.[13]　JuwarkarAS,PatnaikSM.Domesticwastewatretreat-mentthroughconstructedwetlandsinIndia[J].WaterSciTechnol,1995,32(3):291-294.:13964090810E-mail:[e-mail]:2008-01-20·105·:24　13
