201129不同人工湿地系统处理生活污水的比较研究*周遗品 刘 雯 林妙娟 雷泽湘(, 510225) :以华南1号杂交狼尾草、海芋、春砂仁、文殊兰、美人蕉、沿阶草、鸢尾和红草为湿地植物,以煤渣、麻石、陶粒为填料构成几种人工湿地系统,对生活污水进行处理研究。结果表明:当进水COD浓度小于345mg/L时,各系统出水COD浓度均小于60mg/L(停留时间为6h),达到GB18918-2002的一级B标准;当进水TP浓度在4.44~8.17mg/L之间,NH4+-N浓度在41.3mg/L以下,TN浓度在66.1mg/L以下时,各系统出水TP、氨氮、总氮浓度分别小于1,25,20mg/L(停留时间为12h),均达到GB18918-2002的二级B标准。:人工湿地;生活污水;水力停留时间;化学需氧量COMPARISONOFDIFFERENTCONSTRUCTEDWETLANDSYSTEMSFORSEWAGETREATMENTZhouYipin LiuWen LinMiaojuan LeiZexiang(CollegeofEnvironmentalScienceandEngineering,ZhongkaiUniversityofAgricultureandEngineering,Guangzhou510225,China)Abstract:Comparisonofdifferentconstructedwetlandsystemstotreatsewagewascarriedout.Theremovalefficiencyofmainpollutants(COD,TN,TP,NH4+-N)insewagebyeightconstructedwetlandplantswasinvestigated.Pennisetumamericanum23A×P.purpuerumcv.N51cv.HuananNo.1,Alocasiamacrorrhiz-os,Amomumvillosum,ChineseCrinum,Cannaindica,Ophiopogonreversus,IristectorumandAlternantherabettzickianawereusedaswetlandplants.Ceramic,granite,cinderwereusedasthefillers.TheresultsshowedthatwhentheCODofsewagewas345mg/Lbelow,thehydraulicresidencetime(HRT)was6h,theCODofsewagetreatedbyfourconstructedwetlandssystemslessthan60mg/L.WhentheTP,NH4+-NandTNofsewagewere4.44~8.17,66.1,41.3mg/Lrespectively,andHRTwas12h,TP,NH4+-NandTNoftheef-fluentfromfourconstructedwetlandssystemswerelessthan1,25,20mg/Lrespectively.TheeffluentqualityreachestheclassⅡcriteriainTheDischargeStandardofPollutantsforMunicipalWastewaterTreatmentPlant(GB18918-2002).Keywords:constructedwetlands;domesticsewage;hydraulicresidencetime;chemicaloxygendemand*(2008B060600005)。 1953Max-Planck,Seidel;2060,SeidelKickuthKickuth1972;2080,[1-3]。,,,,,、。,。、。1 1.1 试验用人工湿地系统,,1,1。1.2 (),2。127DOI:10.13205/j.hjgc.2011.s1.065 2011291 ::××=1000mm×1000mm×1300mm;:××=4000mm×1000mm×740mm。1.3 试验方法1.3.1 ,6,12,24,36,48h。2,TN、TP、NH4+-N、NO3--N、COD。1.3.2 COD[5];TP(GB11893-89);TN(GB11894-89);NH4+-N(GB7479-87)[6]。1 11[4]Pennisetumamericanum23A×P.purpuerumcv.N51cv.HuananNo.1(68%)、(40%)(37%)Alocasiamacrorrhiza(L.)Schott2AmomumvillosumLour.(31%)、CrinumasiaticumL.var.sinicum(Roxb.exHerb.)Baker3CannaindicaL.、OphiopogonreversusHuang4IristectorumMaxim.、Alternantherabettzickiana(Regel)Nich.2 ρ(COD)/(mg·L-1)ρ(TN)/(mg·L-1)ρ(TP)/(mg·L-1)ρ(NH3-N)/(mg·L-1)108~34524.87~127.691.90~8.1721.45~96.192 2.1 COD的去除情况比较COD157~345mg/L,6h,4COD60mg/L,GB18918-2002《》B(≤60mg/L)。4,4,COD321mg/L,6h,CODGB18918-2002A(≤50mg/L)。6~48h,,COD。,,GB18918-2002B(≤60mg/L),COD345mg/L,≥6h,COD。4COD2。2:,6h48h,80%90%。46hCOD78%,4,COD321mg/L,6h89%。2 COD2.2 TP去除情况比较TP4.44~8.17mg/L,6h,70%,1TP8.17mg/L、6h67.1%(70%)。6h,TP1.0mg/L,GB18918-2002(≤3mg/L)。,,1-4TP3。,,12h,TPGB18918-2002B(≤1mg/L)。4,2128 2011293TP,TP,6~48h,TP0.5mg/L,90%,GB18918-2002A。3 TP2.3 TN去除情况比较14TN,,TN≤66.1mg/L(12h),4TNGB18918-2002B(≤20mg/L),24h,GB18918—2002A(≤15mg/L)。TN127mg/L,6h,440mg/L。,TN,。TN,TN80%。4 TN2.4 NH4+-N去除情况比较NH4+-N41.3mg/L,1-412hGB18918-2002(≤25mg/L),NH4+-N62.48mg/L,6h,425mg/L。,NH4+-N,。,,48h,NH4+-N80%。3 1),COD、TP、TN、NH4+-N,6,12,24,36,48h,。5 NH4+-N2)1-448hCOD91.9%、89.87%、86.53%88.59%,GB18918-2002B;TP83.79%、94.06%、93.45%88.29%。24h,1、4TPGB18918-2002B,2、3TPGB18918-2002A;TN71.92%、68.74%、75.82%、76.79%,TNGB18918-2002B;NH4+-N72.61%、69.00%、76.75%、77.91%,NH4+-NGB18918-2002。3)1COD,2TP,34。,、、,,,TP、TN。[1],,,.[J].,2005,24(6):125-129.[2]MiklasScholz,JingXu.Performancecomparisonofexperimentalconstructedwetlandswithdifferentfiltermediaandmacrophytestreatingindustrialwastewatercontaminatedwithleadandcopper[J].BioresourceTechnology,2002,8(3):71-79.[3],.[J].,2007,27(2):60-61.[4],,,.1[J].,2004,17(1):56-59.[5],,,.[M].:,2003:46-47.[6]《》.[M].:,2002. 510225 24 E-mail zyp18203@163.com2010-11-12129
