安徽工程大学毕业设计（论文）垃圾渗滤液废水站设计摘要渗滤液是一种作为渗流通过废物的雨水和水分而形成于堆填区高强度污染废水。在垃圾渗滤液，有机物质的形成是从废物转移到液体容纳体中，造成危害的接收水体。垃圾渗滤液具有NH3-N高、COD浓度高等特点，传统的处理工艺往往存在较大的压力，出水水质难以得到保证。MBR工艺很好地解决了这方面的问题，在先进的生物处理工艺中，膜生物反应器（MBR）是最重要的过程，模块和膜一般含有高混合液悬浮固体活性污泥（污泥）生物反应器组成一个比10，000mg/L更大的系统时，膜生物反应器作为物化后处理中的应用可以达到预期的高水质标准。MBR工艺对污染物去除率高，对污水变化适应性也很强，系统启动速度快，另外，该工艺节约占地，操作、维护简单。逐步成为国内外垃圾渗滤液处理的主流工艺之一。关键词：膜生物反应器；垃圾渗滤液；纳滤-I-安徽工程大学毕业设计（论文）AbstractLeachateisahighstrengthwastewaterformedasaresultofpercolationofrain-waterandmoisturethroughwasteinlandfills．Duringtheformationofleachate，organicandinorganiccompoundsaretransferredfromwastetotheliquidmediumandposeahazardtothereceivingwaterbodies．TreatmenttechniqueofgarbageseepingfiltratesischaracterizedinhighNH3-NandCODconcentration.Traditionaltreatmenttechniquetendstohavesometreatmentpressureandcannotguaranteetheeffluentwaterquality.MBRtechniquesolvesthisproblemideallyandhastheadvantagesofhighrateofremovalofpollutants，Amongadvancedbiologicaltreatmentprocesses，membranebio-reactor(MBR)isthemostimportantprocess，whichconsistsofamembranemoduleandabioreactorcontaininggenerallyactivatedsludgewithhighmixedliquorsuspendedsolids(MLSS)ofgreaterthan10，000mg/l．Theapplicationofmembranebioreactorasamaintreatmentafterphysicochemicalapplicationseemstobepromisingduetotheexpectedhigheffluentquality．MBRtechniquehighadaptabilitytosewagechangeandquicksystemstartup.Besides，theintegrativeequipment，whichgraduallybecomesthemainstream.techniqueofgarbageseepingfiltratestreatmenthomeandabroad，issimple，compact，easytooperateandmaintainandhassmallsize.Keywords：membranebioreactor；treatmenttechniqueofgarbageseepingfiltrates；NF-II-安徽工程大学毕业设计（论文）目录引言....................................................................1第1章绪论.............................................................21.1选题研究的意义......................................................21.2垃圾渗滤液处理在国内外的研究现状.....................................21.2.1城市垃圾渗滤液的现状.............................................21.2.2城市垃圾渗滤液发展趋势...........................................31.3本论文主要研究内容..................................................4第2章垃圾渗滤液处理的工艺流程选择.......................................52.1垃圾渗滤液的概述.....................................................52.2工艺的选择...........................................................52.2.1光催化氧化法.....................................................52.2.2回灌法...........................................................52.2.3吹脱、混凝沉淀－SBR组合工艺.....................................62.2.4A2/O法生物二级脱氮工艺..........................................62.2.5MBR膜处理法.....................................................7第3章设计计算...........................................................83.1调节池的设置........................................................83.2硝化与反硝化池池体设计...............................................93.3超滤膜...
