错流流速对厨余垃圾厌氧膜生物反应器通量的影响研究吴健1,华银锋2,陈卫华1(1.上海黎明资源再利用有限公司,上海201209;2.上海浦东环保发展有限公司,上海200127)【摘要】对上海市某厨余垃圾处理厂的中试规模厨余垃圾浆料厌氧膜生物反应器(AnMBR)进行了研究,重点探索了AnMBR处理过程中错流流速对厌氧膜通量的影响。结果表明,错流流速与AnMBR的膜通量密切相关。在试验错流流速下,沼液的AnMBR亚临界通量为18.48L/(m2·h),相应的膜过滤阻力R为2.53×1012m-1,此膜过滤阻力为清水的1.12倍。修正后的惯性升力模型表明,运用该修正模型对不同错流流速下AnMBR沼液膜通量拟合获得的沼液悬浮污染物颗粒平均半径a为(4.375±0.032)μm,膜通量修正值b为(3.172±0.198)L/(m2·h)。【关键词】厨余垃圾浆料;厌氧膜生物反应器;错流流速;膜通量中图分类号:X799.3;X703文献标识码:A文章编号:1005-8206(2023)02-0070-07DOI:10.19841/j.cnki.hjwsgc.2023.02.011EffectStudyofCross-FlowVelocityonMembraneFluxofAnMBRforFoodWasteWUJian1,HUAYinfeng2,CHENWeihua1(1.ShanghaiLimingResourcesReuseCo.Ltd.,Shanghai201209;2.ShanghaiPudongEnvironmentalProtectionDevelopmentCo.Ltd.,Shanghai200127)【Abstract】Theinvestigationofapilot-scaleAnMBRforthetreatmentoffoodwasteslurryfromafoodwastetreatmentplantinShanghaiwascarriedout.Primarilyfocusedontheimpactofcross-flowvelocityonmembranefluxduringAnMBRtreatment.Thefindingsindicatedastrongcorrelationbetweenthecross-flowvelocityandthemembranefluxofAnMBR.TheAnMBRsubcriticalfluxforthebiogasslurrywas18.48L/(m2·h)undertheexperimentalcross-flowvelocity,andthecorrespondingmembranefiltrationresistanceRwas2.53×1012m-1,whichwas1.12timesthatofwater.Accordingtothemodifiedinertialiftmodel,theaverageradius(a)ofthesuspendedbiogasslurrypollutantparticlesandthemembranefluxcorrectionvalue(b)were(4.375±0.032)μmand(3.172±0.198)L/(m2·h),respectively,whichweredeterminedbyfittingtheAnMBRbiogasslurrymembranefluxwiththemodifiedmodelatvariouscrossflowvelocities.【Keywords】foodwasteslurry;AnMBR;cross-flowvelocity;membraneflux1引言上海市自2019年7月开始强制推行生活垃圾分类工作。随着生活垃圾分类工...
