垃圾渗沥液处理优化组合工艺_沈林华

垃圾渗沥液处理优化组合工艺沈林华（绍兴县市容环境卫生管理处，浙江绍兴312030）摘要：分析了生化法处理垃圾渗沥液与一般生活污水的不同点，提出一种优化组合工艺：调节池＋混凝初沉＋氨吹脱＋UBF厌氧反应器＋MBBR好氧反应器＋MBR。阐述了调节池、混凝初沉、UBF厌氧反应器和MBBR好氧反应器的设计、技术优势及实际工程中应注意的问题。该工艺高效低耗，运行稳定，出水达到GB16889—1997二级标准要求。关键词：垃圾渗沥液；调节池；混凝初沉；UBF厌氧反应器；MBBR好氧反应器中图分类号：X703文献标识码：A文章编号：1005－8206（2008）06－0031－03OptimizationGroupingTechnicsofWasteLeachateTreatmentShenLinhua（ShaoxingCountyAppearanceEnvironmentalSanitationManagementDepartment,ShaoxingZhejiang312030）Abstract：Thedifferencesbetweenthebiochemicaltreatmentofwasteleachateandthegeneralsewagewereanalyzed.Anoptimizationprocessofregulatingtank+coagulating-primarysettling+ammoniapurging+UBFanaerobicreactor+MBBRaerobicreactor+MBRwasproposed.Thedesign,technicaladvantagesandpracticalengineeringproblemsofregulatingtank,coagulatingandprimarysetting,UBFanaerobicreactor,andMBBRaerobicreactorwereelaborated.Theprocesshasthefeaturesofhighefficiency,lowconsumption,andstableoperation,itsqualityofeffluentwatermettheⅡdegreerequirementofGB16889—1997.Keywords：wasteleachate
