垃圾渗滤液废水站设计

安徽工程大学毕业设计（论文）-I-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；纳滤陈婷姣：垃圾渗滤液废水站设计-II-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安徽工程大学毕业设计（论文）-III-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超滤膜反应器的设计计算.............................................103.4清液罐的设计计算...................................................103.5纳滤膜的设计计算...................................................113.6污泥池的设计计算...................................................113.7主要设备选型.......................................................113.8设计污染物去除率和处理效果.........................................13第4章高程布置.........................................................15第5章平面布置.........................................................17第6章工程概算.........................................................196.1土建费用概算表.....................................................196.2设备费用概算.......................................................206.3工程总费用概算.....................................................206.4运行费用...........................................................21致谢..................................................................22参考文献................................................................23附录1：题录.............................................................24附录2：外文原文.........................................................28附录3：外文翻译.........................................................33陈婷姣：垃圾渗滤液废水站设计-IV-表格清单表3-1NF纳滤设备......................................................11表3-2增压泵相关参数..................................................12表3-3渗滤液处理厂各处理单元水质分析..................................13表5-1主要构筑物列表..................................................17表6-1构筑物清单......................................................19表6-2设备清单........................................................20表6-3本次设计的运行费用..............................................21安徽工程大学毕业设计（论文）-V-插图清单图2—1光催化氧化法....................................................5图2—2回灌法..........................................................5图2—3工艺图..........................................................6图2-1MBR膜处理系统工艺流程.............................................7图2-4MBR膜生物反应器..................................................7图3—1调节池..........................................................8图3-2清液罐示意图.....................................................11图3-3搅拌机示意图.....................................................12安徽工程大学毕业设计（论文）-1-引言城市垃圾处理一直是各国需要解决的一个很重要的问题，随着城市
