抚仙湖马料河复合人工湿地的除磷效果分析和丽萍

　　　200927抚仙湖马料河复合人工湿地的除磷效果分析和丽萍　陈　静　田　军(,　650034)　:对马料河复合人工湿地的除磷效果进行分析结果表明,整个湿地系统的TP及PO43-去除率约为40%,从各工艺段TP去除率来看,氧化塘湿地最高,表面流湿地次之,潜流湿地最差。PO43-占TP的浓度构成比例从进水的48.3%上升至出水的53.9%,说明湿地系统对磷的去除主要是通过对不溶性磷的吸附和沉积作用,植物、藻类等对无机可溶性磷酸盐的吸收作用并不明显。湿地系统的最佳水力负荷为0.1～0.4m3/(m2·d),TP最佳污染负荷为0.1～0.3mg/L。:人工湿地;含磷物质;去除效果ANALYSISOFPHOSPHORUSREMOVALEFFECTOFMALIAOHECOMPOSITECONSTRUCTEDWETLANDINFUXIANLAKEAREAHeLiping　ChenJing　TianJun(YunnanAcademyofEnvironmentalSciences,Kunming650034,China)Abstract:Itwasanalyzedthephosphorusremovaleffectofmaliaohecompositeconstructedwetland.TheresultshowedthattheremovalrateofTPandPO43-inthewholewetlandwasabout40%.TPremovalrateofanoxi-dationpondwetlandwasthehighest,andthatofanunderflowwetlandwasthelowest.FortheTPintheinflu-entandeffluent,PO43-took48.3%and53.9%respectively.TheoptimalhydraulicloadandoptimalTPpollu-tionloadofthewetlandsystemwere0.1～0.4m3/(m2·d)and0.1～0.3mg/L.Keywords:constructedwetland;phosphorus-bearingmatter;removaleffect0　(ConstructedWetland,CW)2070。、、、(1/101/2)。,,、。、,、,。,、,,、。,。1　1.1　人工湿地建设及处理工艺,19868m2(29.8),6143m2,1660m2,11911m2。1.5m3/d,。,1。　　※※※※※※1　1.2　样品采集及测定,2006—2007,(TP)(PO43-)15。4,,。《》。1.3　生态类型与物种组成、、、,、、566DOI:10.13205/j.hjgc.2009.s1.025　　　200927、、、、、、、、、、。、、、、、、。1。1　Oenanthejavanica、Nymphaeatetragona;Eich-horniacrassipesCannageneralisCyperusalternifoliusTyphaminima;AcoruscalamusOenanthejavanica;CyperusalternifoliusP.crispus;P.pectinatus;P.lucensAcoruscalamus;Sagittariasag-ittifoliaNymphoidespeltata1.4　人工湿地的除磷机理、。。,ATP、DNARNA,;,(C60H87O23N12P,),。,4.5%～19%。,。(),,,,;,(),。(PO43-),。,。2　2.1　人工湿地的除磷效果,2、3。,TP0.46mg/L,0.25mg/L,37.73%;PO43-0.22mg/L,0.14mg/L,38.32%;PO43-TP48.3%53.9%,TPPO43-40%。:TP:(64.64%)(33.46%)(-64.55%);PO43-:(27.58%)(12.87%)(-12.03%)。2　3　TPPO43-,,,(3)。TP2.62kg/d,PO43-0.94kg/d,35.9%。,TP2.12kg/d,PO43-0.84kg/d,40%;,TP0.54kg/d,PO43-0.29kg/d,53.7%;,TPPO43-。567　　　2009272。2　TP/%/(kg·d-1)/%PO43-/%/(kg·d-1)/%64.642.1251.1812.870.8476.00-64.55-0.04-23.55-12.03-0.19-41.7733.460.5472.3727.580.2965.7737.732.62100.0038.320.94100.002.2　各工艺段含磷物质净化效果2.2.1　(TP)TP37.73%,TN2.62kg/d。TP,,,。:TP:(64.64%)(33.46%)(-64.55%),TN:(51.18%)(72.37%)(-23.55%)。,,64.64%。,TP,。,。,,,,,。,,33.46%,。,,。,,,,。2.2.2　(PO43-)PO43-38.32%,PO43-0.94kg/d。PO43-:(27.58%)(12.87%)(-12.03%),PO43-:(76.00%)(65.77%)(-41.77%)。,12.87%,,。,,。,。,,,,,。,、48.3%53.9%。、。,,。(Ca2+、Fe3+、Al3+),,。,“”。2.3　湿地系统除磷效果的影响因素2.3.1　,,0.15～2.18m3/(m2·d),0.73m3/(m2·d)。,3,;,0.13～0.15m3/(m2·d),,。34。3　/(m3·m-2·d-1)/%20.7～0.80.60.50.40.30.20.12.6017.730.631.747.445.448.245.0　　3,TN。0.1～0.4m3/(m2·d),TP40%～50%;0.5～0.6m3/(m2·d),TP30%;0.7～0.8m3/(m2·d),TP20%;2.0m3/(m2·d),TP10%。,,TP。,,,TP。,568　　　200927,0.1～0.4m3/(m2·d)。2.3.2　,,。TP。TP1.0～2.0mg/L,33.5%;TP0.3～1.0mglL,45%;TP0.3mg/L,60%。,,TP0.1～0.3mg/L。44a、4b。4　/(mg·L-1)/%1.0～2.00.7～1.00.3～0.60.1～0.31.40.920.460.2433.542.546.762.74　、2.3.3　,,,,、,,,,、,,。4-10,,,15cm160cm,9.6;3875,97%;30cm70cm,1.3。130cm300cm,1.3;270920,2.4;70cm270cm,3.9。,、,TP50%。(12-2),、,,TP30%。,,,。,,,,。,,,,;,;,。,TP51.1%,65.4%,45.9%,31.0%。,、。,,,,;,、,,。3　1)TPPO43-40%。TP,,,。PO43-:(27.58%)(12.87%)(-12.03%)。PO43-TP(442)569　　　200927　　　　V———,mL。,0.070mol/L;,。:1%5　;;;。6　200。105～110℃1h,,。7　1.0,1.5,2.0g0.0002g。200mL,,30,40℃,100,150mL(),(500r/min),,,。8　1。1　/g/mL/s/℃1.0082100232301.5009100165302.0017100232301.0071100116401.5076100156402.009010060401.0075150300401.500915078402.006415092409　1),,,。2),,。11.5g,100mL。40℃。。。3):,,,,,。4),、,,,。,,,,。[1]YB4019-1991.[S].[2],.[J].,1988(4):277-279.[3],.MgO[J].,1986,14(2):226-228.　　100085　E6　　(010)62966600-8051E-mail　[e-mail]2009-04-01(569)48.3%53.9%,,,,。,,、。2),、、。,,0.1～0.4m3/(m2·d),TP0.1～0.3mg/(L·d)。[1],.[J].,2005(2):1-4.[2].[J].,1991,10(9):25-28.[3].[J].,2003,20(4):54-58.[4].[J].,1999,32(6):31-34.[5],.[J].,2004,16(4):28-31.[6],.[J].,2003(2):33-35.　　650034　23　　(0871)4154590E-mail　[e-mail]　QQ:2748370022009-03-04442
