某垃圾填埋场渗滤液处理工程初步设计

陕西理工学院毕业设计某垃圾填埋场渗滤液处理工程初步设计张斌（陕西理工学院化工学院环境工程1102班，陕西汉中723001）指导教师：李琛摘要：本设计针对400t/d的垃圾填埋场渗滤液的处理工艺进行设计。渗滤液废水水质复杂，属于典型的高浓度难降解有机污染废水，其水质特点表现为有机物含量高、COD、BOD高、pH低等特点。设计采用“吹脱→与ABR→SBR→活性炭吸附深度处理”工艺对垃圾填埋场渗滤液进行处理。废水水质CODBODSSNH3-N9000mg/L3600mg/L1200mg/L1500mg/L渗滤液经本工艺处理后，COD、BOD、NH3-N及SS的去除率分别为98.9%、99.2%、98.4%及97.5%，满足《生活垃圾填埋场污染控制标准》（GB16889-2008）一级排放标准。关键词：渗滤液；吹脱；ABR；SBR；活性炭吸附陕西理工学院毕业设计DesignofMunicipalSolidWasteLandfillLeachateTreatmentProcessZhangBin(Grade2011,Class02,Majorenvironmentalengineering，ShaanxiUniversityofTechnology，Hanzhong723000，Shaanxi）Tutor:LiChenAbstract:Designof400m3/dofmunicipalsolidwastelandfillleachatetreatmentprocesswasproposed.Leachatewithcomplexsubstanceswastypicalanddifficultlydegradedeffluentthatcontainsconcentrationoforganicpollutants.Ithasthefeaturesofhighorganiccontent,CODCr,BOD5,andlowpHvalues.Municipalsolidwastelandfillleachatewastreatedbytheprocessof“airstripping→ABR→SBR→activecarbonadsorption”withthewastewaterqualityof9000mg/LCOD,1200mg/LSS,3600mg/LBOD,1500mg/LNH3-N.Aftertheleachatewastreatedbytheprocess,theremovalrateofCOD,BOD,NH3-NandSSwasabout98.9%、99.2%、98.4%and97.5%,andthequalityofwatermettheFirstGradeStandardofStandardforPollutionControlontheLandfillSiteofMunicipalSolidWaste（GB16889-2008）.Keyword:leachate,airstripping,ABR，SBR，activecarbonadsorption陕西理工学院毕业设计目录1垃圾填埋场渗滤液概况....................................11.1城市生活垃圾的现状及趋势................................11.2渗滤液的来源、水质及水量特点分析........................11.2.1渗滤液的来源：.....................................11.2.2渗滤液水质特点：...................................11.2.3渗滤液水量特点：...................................22设计概述................................................22.1设计的题目..............................................22.2设计原则................................................22.3设计依据................................................22.3.1法律法规依据.......................................22.3.2技术标准及技术规范依据.............................32.3.3设计范围...........................................32.3.4执行排放标准.......................................32.4设计工艺比选............................................32.5设计工艺流程图..........................................43主要构筑物设计计算......................................43.1集水池的设计............................................43.1.1设计说明...........................................43.1.2设计参数...........................................4陕西理工学院毕业设计3.1.3设计计算...........................................43.2调节池的设计计算........................................43.2.1调节池的作用.......................................43.2.2设计参数...........................................43.2.3设计计算...........................................53.3吹脱塔的设计计算........................................53.3.1设计说明...........................................53.3.2设计参数...........................................63.3.3设计计算...........................................63.4ABR池的设计计算........................................73.4.1设计说明...........................................73.4.2设计参数...........................................73.4.3设计计算...........................................83.5SBR池的设计计算........................................83.5.1设计说明...........................................83.5.2设计参数...........................................93.5.3设计计算...........................................93.6混凝沉淀池的设计计算...................................143.6.1设计说明..........................................143.6.2设计参数..........................................143.6.3设计计算..........................................143.7污泥浓缩池设计计算：...................................22陕西理工学院毕业设计3.7.1设计说明：........................................223.7.2设计参数..........................................233.7.3设计计算..........................................233.8吸附塔的设计计算.......................................263.8.1设计说明..........................................263.8.2设计参数..........................................263.8.3设计计算..........................................263.9消毒池的设计计算.......................................273.9.1设计说明..........................................273.9.2设计参数..........................................273.9.3设计计算..........................................274管道及布置设计计算.....................................284.1污水管道计算...........................................284.1.1设计原理..........................................284.1.2各构筑物水头损失计算..............................284.1.3污水管道水头损失的计算............................305工程概算及处理成本.....................................325.1工程投资估算...........................................325.1.1建设费用..........................................325.1.2设备费用..........................................325.1.3管材及附件费用....................................325.1.4管材附件费用......................................32陕西理工学院毕业设计5.1.5其他费用..........................................325.2劳动定员、运行管理.....................................335.2.1劳动定员..........................................335.2.2运行费用..........................................33结论.....................................................34参考文献.................................................34致谢............
