第1页共37页陕西理工学院毕业设计某生活垃圾填埋场垃圾渗滤液处理工艺设计作者：张欢乐（陕西理工学院化学与环境科学学院环境工程1102班陕西汉中723000）指导教师：刘瑾[摘要]：垃圾填埋过程中伴随有垃圾渗滤液的产生，垃圾渗滤液是种特别难处理的并且有毒有害的高浓度有机废水,这种废水的处理是当前必须首要解决的问题，若这种有机废水不能得到有效处理不仅会引起地表水、地下水以及土壤的严重二次污染,而且相应的生态系统和人体健康也受到很大威胁。本设计处理量为150吨每天。采用上流式厌氧污泥反应床（UASB)-生物接触氧化池组合工艺，并且对吹脱塔、上流式厌氧污泥反应床（UASB)、生物接触氧化池等主要构筑物进行设计说明和计算。该工艺技术成熟、操作简单占地面积小、投资少、运行费用低、处理效果稳定，经处理后渗滤液经处理后出水水质标准可达到《中华人民共和国污水综合排放标准》（GB8978-1996）中规定一级标准。[关键词]：垃圾渗滤液，氨氮，生物接触氧化第2页共37页陕西理工学院毕业设计ALandfillLeachateTreatmentProcessDesignZhangHuanle(Grade10,Class2,CollegeofChemical&EnvironmentScience,ShaanxiUniversityofTechnology,Hanzhong723000,Shannxi)Tutor:LiuJingAbstract：Landfillprocessisaccompaniedbythegenerationofleachate,landfillleachateisakindofspecialrefractoryandhazardoushighconcentrationorganicwastewater,thewastewateriscurrentlymustfirstsolvetheproblem,ifthisorganicwastecannoteffectivetreatmentnotonlycausesserioussecondarypollutionofsurfacewater,groundwaterandsoil,andthecorrespondingecosystemsandhumanhealtharealsoundergreatthreat.Thedesigncapacityof150tonsperday.Thereactionusingupflowanaerobicsludgebed(UASB)-biologicalcontactoxidationpondcombinedprocess,andthestrippingtower,upflowanaerobicsludgereactorbed(UASB),biologicalcontactoxidationpondsandothermajorstructuresdesignandcalculationinstructions.Thetechnologyismature,easytooperatesmallfootprint,lowinvestment,lowoperatingcosts,stabletreatmenteffect,aftertreatmentthetreatedleachatewaterqualitystandardscanbeachieved,"People'sRepublicofChinaIntegratedWastewaterDischargeStandard"(GB8978-1996)theprovisionsofthestandards.Keywords:Landfillleachate,Ammonianitrogen，Biologicalcontactoxidation第3页共37页陕西理工学院毕业设计目录引言.............................................................................................................................................................11概述.........................................................................................................................................................21.1垃圾渗滤液特征........................................................................................................................21.2垃圾渗滤液的处理方法介绍.................................................................................................21.2.1生物法处理渗滤液.......................................................................................................21.2.2物化法..............................................................................................................................31.2.3土地法..............................................................................................................................42.设计依据和设计内容................................................................................................................52.1设计背景资料.............................................................................................................................52.2设计水量水质和排放标准............
