UASB－曝气法应用于饮料废水中出现的问题及分析*熊鸿斌陈雪赵娜娜(合肥工业大学资源与环境工程学院，合肥230009)摘要:UASB－曝气法应用在饮料废水处理的前期运行良好，但运行后期出现了出水不达标的异常现象，通过运行数据和UASB常见问题的分析，发现使系统出现异常的原因是UASB反应器内部腐蚀、三相分离器不完善等的常见问题。针对这些问题提出了相应的解决措施和二次启动厌氧池的建议，以使该系统恢复运行效果。关键词:饮料废水;UASB反应器;三相分离器;国家标准PROBLEMSOFUASB-AERATIONAPPLIEDINTHETREATMENTOFBEVERAGEWASTEWATERANDANALYSISXiongHongbinChenXueZhaoNana(SchoolofResourcesandEnvironmentalEngineering，HefeiUniversityofTechnology，Hefei230009，China)Abstract:UASB-Aerationusedinthetreatmentofdrinkwastewaterwasrunningwellinthebeginning.Butitwasappearedabnormalphenomenaofeffluentthatcouldnotaccordwithnationalstandardsinthelaterrunning.AccordingtooperatingdataandanalysisoffrequentproblemsinUASB，thereasonswhichsystemweretheinternalcorrosionofUASBreactorandthedefectofthree-phaseseparatoretc.Tosolvetheseproblems，itwasadvancedsomecorrespondingmeasuresinthispaper.Andadviceofthesecondstartupoftheanaerobicpondwasraisedinordertomakethesystemhaveoperationeffectagain.Keywords:beveragewastewater;UASBreactor;three-phaseseparato
