沸石在废水脱氨氮中的应用沸石生化结合脱氨氮汪超

:(Ⅱ)　,　,　,　(,200237)　:沸石生化结合脱氨氮技术是一项新型生物脱氨氮技术。这种技术把沸石对铵根离子的选择性吸附能力和生物硝化反硝化结合起来,加强生物脱氨氮系统的性能和效率,能缓冲氨氮进水冲击负荷,降低出水的浊度,减少出水悬浮颗粒的浓度,促进铵根离子的传输,提高脱氮效果。在运行过程中,沸石可以连续生物再生,长期循环使用。加强这方面的研究应用,将有广阔的前景。:沸石;废水;氨氮;硝化反硝化;离子交换:　(1978～),,。　　,,。,2.6×10-2mg/L[1]。,NH3-HNO-3-N4.57mg,[2]。,,,。[3]。,、、。,[4]。、,、、,,,,,。,。。,。1　,,,。,,,。,,,,,,。、,,。,。LahavOri,25%～30%,,。NH+4,3～4,,,[5]。,。pH、、、、、[6-10],pH、DO、。、pH、DO、、。2　2.1　Orilahav,。,。,。,·63·　　　　　　　　　　　DOI:10.19500/j.cnki.0367-6358.2002.s1.024,,。,pH。,。,:,,,。,,。,,,,。,,,。,[11,12]。3,:(Ⅰ),(Ⅱ)BOD,,(Ⅲ)[13]。Charuckyi,,,,,[14]。Kataoka,,,,,,[15,16]。2.2　GisvoldB,。,,,,。。Leca,,。DO()6.5～11.5mg/L,T()11.0～17.1°C,0.3～3.9m/h。,。,8～10d。,(50%)。。。,,3～4h,。4d。10d。:,Leca。Leca2～3,。Leca,。,Leca[17]。,10,。,8。,[18]。2.3　O/AChung,Y-CO/A(/),。。,300～400mg/L。,,。,,。O/A,。88%～92%,。,O/A[19]。DaeHee,。,O/A97%。,,[20]。Kataoka。,,,·64·　　　　　　　　2002。,[21]。2.4　WildererSB-BR()。,、,,[22]。LeiYang。,,1～2nm。,,。10mg/L20mg/L,。50mg/L,70mg/L,100mg/L,,,。。,[23]。3　,,。,。,[24-26];,;,,,,,;,,,。,,。:[1]　TrinkelM,TrettnakW,ReiningerF,etal.InternJEnviron[J],1997,67:237-251.[2]　.[J],2001,20(2):12-14.[3]　　,　.[J],1998,24(7):60-63.[4]　,.[M],:,1998.165.[5]　LahavO,GreenM.WaterSA[J],2000,26(1):51-57.[6]　.[J],1998,(5):33-36.[7]　.[J],1997,14(3):40-49.[8]　,,.[J],1992,4:10-16.[9]　,,,.[J],1992,5:6-9.[10]　　,.[J],1999,25(6):358-361.[11]　LahavO,GreenM.WatRes[J],1998,32(7):2019-2028.[12]　GreenM,MelsA,LahavO.WaterScienceandTechnology,1996,34(1-2):449-458.[13]　LahavO,GreenM.WaterSciTechnol[J],2000,42(1-2):179-185.[14]　CharuckyiL,CookseyPA.Denitrificatioinprocess.Australia,CLASS:ICM:C02F001-42.WO2000-AU62231May2000.[15]　Kataoka,Katsushi.Methodforremovalofammoni-umnitrogenfromorganicwastewaterbybiologicalnitrationanddenitrificationwithzeoliteregenera-tion.Japan,CLASS:ICM:C02F003-34.Jpn.KokaiTokkyoKohoJP09314186A29Dec1997.[16]　KataokaKatsuyuki.Methodandapparatusforhigh-lyeffectivedenitrificationofwastewaterusingacti-vatedsludgeprocess.Japan,CLASS:ICM:C02F003-34.ICS:C02F003-34.Jpn.KokaiTokkyoKohoJP09314183A29Dec1997.[17]　GlsvoldB,OdegaardH,FollesdalM.WaterSciTechnol[J],2000,41(9):107-114.[18]　GisvoldB,OdegaardH,FollesdalM.WaterSci.Technol[J],2000,41(4-5):409-416.[19]　ChungY-C,SonD-H,AhnDH.WaterScienceandTechnology[J],42(5-6):127-134.[20]　DaeHeeSon,DongWookKim,YunChulChung.Biotechnol.Lett[J],2000,22(1):35-38.[21]　Kataoka,Katsuyuki.Highlyefficientdenitrificationoforganicwastewaterbybiologicalandchemicalpro-cesses.Japan,CLASS:ICM:C02F003-34.Jpn.KokaiTokkyoKohoJP09075988A225Mar1997.[22]　WildererPA,ArnzP,ArnoldE.WaterAirandSoilPollution[J],2000,123(1):147-158.[23]　LeiYang.WatSciTech[J],35(8):169-175.[24]　MartinO,IvanS.WatSciTech[J],1995,32(7):199-206.[25]　BaykalBB.WatSciTech[J],1998,37(9):235-242.[26]　BilsenBB,MartinO,IvanS.WatRes[J],1994,28(9):2039-2042.·65·
