内循环三相生物流化床处理味精废水*张晶晶冯旭东温伟庆王丝雨谷丽王骅伟(北京工商大学化学与环境工程学院，北京100048)摘要:利用混合异养硝化－好氧反硝化菌群在内循环三相流化床内处理实际味精废水，以火山岩为载体，考察了反应器的启动和驯化，分析了污染物进水浓度变化对处理效果影响和同步硝化反硝化效果。结果显示，经过10d的间歇闷曝，微生物附着在载体表面，挂膜成功;经驯化可处理较高浓度的味精废水并具有较强耐冲击能力;同步好氧硝化反硝化效果良好。关键词:味精废水;内循环三相流化床;好氧同步硝化反硝化TREATMENTOFMONOSODIUMGLUTAMATEWASTEWATERBYINNER-LOOPTHREE-PHASEFLUIDIZEDBEDZhangJingjingFengXudongWenWeiqingWangSiyuGuLiWangHuawei(CollegeofChemicalandEnvironmentalEngineering，BeijingTechnologyandBusinessUniversity，Beijing100048，China)Abstract:Thetreatmentofmonosodiumglutamatewastewaterbyinner-loopthree-phasefluidizedbedcoupledwiththeheterotrophicnitrification-aerobicdenitrificationstrainswasinvestigatedwithlavaparticlesascarriers．Thestartinganddomesticationprocessesofthereactorhavebeenstudied．Furthermore，theeffectofpollutantsconcentrationvariationontreatmentandtheexpressionofsimultaneousnitrificationanddenitrficationwasanalyzed．Theresultsshowedthatmicroorganismhadsettledonthesurfaceofcarriersin10days．Thesystemhadsuccessfullyeliminatedthehig
