厌氧颗粒污泥床反应器污泥的流失与对策_胡勇

工业用水与废水INDUSTRIALWATER&WASTEWATERVol.38No.4Aug.,2007厌氧颗粒污泥床反应器污泥的流失与对策摘要:厌氧颗粒污泥的流失是高效厌氧反应器实际运行中经常发生的现象,污泥流失严重时会导致反应器性能大大地降低。从颗粒污泥的沉降性能与反应器的操作条件等角度深入探讨了颗粒污泥流失的原因,指出提高颗粒污泥的沉降性能是防止污泥流失的根本途径,控制厌氧反应器的有机负荷是控制污泥过量流失的主要方法。关键词:厌氧反应器;颗粒污泥;废水处理;污泥流失中图分类号:X703文献标识码:A文章编号:1009-2455(2007)04-0006-03Sludgewash-outfromanaerobicgranularsludgebedreactorandcountermeasurethereofHUYong1,SHANGLian-sheng2,LIUYong-hong3,YUCui-hua3(1.HuizhouFilialeChinaNationalOffshoreOilCorporation,HuiZhou516084,China;2.BaojiEnvironmentalProtectionMonitoringStation,Baoji721006,China;3.DepartmentofAppliedChemistry,Xi′anEngineeringandTechnologyCollege,Xi′an710048,China)Abstract:Anaerobicgranularsludgewash-outisaphenomenonthatcommonlyhappensinthepracticaloperationofhighefficiencyanaerobicreactor,andthetreatmentcapabilityofthereactorwouldbegreatlydecreasediftheconditionisserious.Thereasonsthatcausedthegranularsludgewash-outwasdeeplydiscussedfromtheaspectsofsedimentationperformanceofthegranularsludge,operationconditionoftherea
