好氧颗粒污泥处理高氨氮养殖废水的试验研究谢磊

谢磊1,徐勇军2　(1.,421001;2.,523808)　[目的]探寻好氧颗粒污泥处理高氨氮养殖废水过程中的影响因素,为工程实践提供理论依据。[方法]采用好氧颗粒污泥处理高氨氮猪场废水,研究化学需氧量(COD)、溶解氧(DO)和氨氮的去除率变化。[结果]在进水COD为1000mg/L,氨氮质量浓度为50mg/L的条件下,COD与氨氮的去除率均随处理时间增加而上升,但COD的去除效率远高于氨氮,处理4h后,氨氮去除效率为55%,而COD去除效率接近90%。平稳运行下亚硝酸盐与硝酸盐浓度随时间的变化,始终稳定在较低的水平。[结论]采用好氧颗粒污泥处理高氨氮养殖废水具有良好的COD和氨氮去除效果,该技术值得推广。　好氧颗粒污泥;养殖废水;生物脱氮　X52　　　A　　　0517-6611(2010)16-08634-02TreatmentofWastewaterwithHighAmmonia-NitrogenConcentrationbyAerobicGranularSludgeXIELeietal　(SchoolofUrbanConstruction,NanhuaUniversity,Hengyang,Hunan421001)Abstract　[Objective]Toexploretheaquaculture-relatedfactorstreatinghighammoniawastewaterbyaerobicgranularsludgeandprovideatheoreticalbasisforengineeringpractice.[Method]Thetreatmentofhighammoniawastewaterusingaerobicgranularsludgewasperformed.Thechemicaloxygendemand(COD),dissolvedoxygen(DO)andammonianitrogenremovalefficiencywerealsodetected.[Result]Aftertreatmentfor4hattheconditionof1000mg/LCODand50mg/LNH4+-N,theremovalefficiencyofCODandNH4+-Nwere90%and55%,respectively.Thenitriteandnitrateconcentrationstabilizedatalowerlevelwithtime.[Conclusion]ThetreatmentofhighammoniawastewaterusingaerobicgranularsludgehasagoodremovalefficiencyofCODandammonianitrogen,anditisworthpromoting.Keywords　AerobicGranularSludge;PoultryWasteWater;Biologicalnitrogenremoval　广东省教育厅自然科学重点项目(06Z025)。　谢磊(1975-),男,湖南湘潭人,博士,讲师,从事废水生物处理技术研究。　2010-04-19　　,。“”,(COD)3000～12000mg/L,800～2200mg/L,SS10[1]。,,,[2]。-,,,。,,。,(DO),/,,。,,,。,NO3-N,[3-4]。,,,。1　1.1　　COD200g/L,NH3-N10g/L,。,COD800mg/L,NH3-N2000mg/L,pH10～11。1.2　　CODCr,NH4+-N、TN、NO2-NNO3--N,YSI5000(DO),pHS-3CpHpH。1.3　　SBR6L,4.5L,36cm,15cm。,,,2～3mm,5mm。2　2.1　　,,,。3,、。15,,2mm。,,152mm,434mm。,43,5mm。2.2　COD　COD1000mg/L,50mg/L,,0.5、1.0、1.5、2.0、3.04.0h。,COD1。1,COD,COD。4h,55%,COD90%。2.3　　,2。2,,0.3mg/L。,。,NO3-,。2.4　　　王强　　卢瑶,JournalofAnhuiAgri.Sci.2010,38(16):8634-86351　CODFig.1　ThechangecurveofthemassconcentrationofCODandNH3-N2　Fig.2　ThechangecurveofthemassconcentrationofNO3-NandNO2--NDO3。3,DO。,,,,。DO、2,DO,,;DO,,3　Fig.3　Thechangecurveofdissolvedoxygenconcentration,NO-2,。3　(1),COD1000mg/L,50mg/L,COD,COD,4h,50%,COD90%。(2),,0.2mg/L,0.3mg/L。(3),,。[1]朱杰,黄涛,范兴建,等.厌氧氨氧化工艺处理高氨氮养殖废水研究[J].环境科学,2009,30(5):1442-1448.[2]王欢,裴伟征,李旭东,等.低碳氮比猪场废水短程硝化反硝化-厌氧氨氧化脱氮[J].环境科学,2009,30(3):815-821.[3]赵志宏,廖德祥,李小明,等.厌氧氨氧化微生物颗粒化及其脱氮性能的研究[J].环境科学,2007,28(4):800-804.[4]熊津,丁桑岚.畜禽养殖废水脱氮除磷研究进展[J].畜牧与饲料科学,2009,30(1):128-129.(上接第8615页)2.3　　2,0.042～0.045mg/kg,0.040～0.043mg/kg。,2。2　Table2　ThearseniccontentindrinkingwatersamplesMethodmg/kgARSD%∥%Recoveryrate0.042～0.0452.492.40.040～0.0433.094.63　,,、、。,,,。[1]ROSEMARYFEENEY,KOUNAVESSAMUELP.VoltammetricMeasure-mentofArsenicinNaturalWaters[J].Talanta,2002,58:23-31.[2]王修中,陈艳玲,王秀霞,等.修饰电极测定土壤沉积物中各赋存状态砷[J].岩矿测试,2004,23(3):168-172.[3]郑亚琴.大米中砷的微波消解———原子荧光光谱测定法[J].职业与健康,2007,23(2):104-105.[4]杨秋利.氰酸酯树脂修饰电极吸附伏安法测定食品中的砷[J].中外健康文摘,2007,4(5):466-467.863538卷16期　　　　　　　　　　　　　　　　谢磊等　好氧颗粒污泥处理高氨氮养殖废水的试验研究
