某啤酒厂废水处理站设计

江苏省高等教育自学考试（2013年）本科毕业论文题目某啤酒厂废水处理站工艺设计专业环境工程主考学校河海大学姓名准考证号专科院校指导教师起止日期-1-摘要本设计是某啤酒厂废水处理站的初步设计。拟建废水处理站的场地为60×100平方米的平坦地，位于主厂区的南面。啤酒生产车间排出的废水可自流到废水处理站边的集水池（V=200m3，池底较废水站地平面低3.00m）。接纳管道管底标高比废水处理站地平面低3米。废水处理站处理规模为15000m³/d。设计进水水质为：SS≤400mg/L；BOD5≤1100mg/L；COD≤1800mg/L；pH：7.5~9.4。出水水质达到《啤酒工业污染物排放标准》（GB19821—2005）中规定啤酒企业排放标准，即：SS：70mg/L；BOD5：20mg/L；COD：80mg/L；pH：6~9。本设计采用的主体工艺是UASB—生物接触氧化工艺。主要构筑物包括格栅、提升泵房、调节池、UASB反应器、生物接触氧化池、竖流式沉淀池、消毒池、污泥提升泵房、污泥浓缩池、脱水机房等。最后，就设计过程中遇到问题进行了探讨，写了一篇小论文；并完成了一段英语论文的翻译工作。关键词：啤酒废水；UASB；生物接触氧化；污泥处理-2-AbstractThisdesignisthepreliminarydesignofabrewerywastewatertreatmentstation.Thewastewatertreatmentstationofthevenuesforthe60×100squaremetersflat,locatedinthesouthofthemainplant.Wastewaterfrombeerproductionworkshopcanflowtothewastewatertreatmentstationontheedgeofthepool(V=200m3,thebottomofthepoolissewagestationgroundplanelow3.00m).Admissionpipebottomelevationthanthewastewatertreatmentstation3meterslowergroundplane.Thewastewatertreatmentstationwithscaleofrecent15000m3/d.Designinfluentqualityas:SS≤400mg/L;BOD5≤1100mg/L;COD≤1800mg/L;pH:7.5~9.4.Effluentqualitytoachievethebeerindustrialpollutantsemissionstandards(GB19821-2005)emissionstandards,enterprisesstipulatedinbeeris:SS:70mg/L;BOD5:20mg/L;COD:80mg/L;pH:6~9.ThemainprocessofthedesignisadoptedUASB-biologicalcontactoxidationprocess.Themainstructuresincludegrid,pumpingstation,adjustingtank,UASBreactor,biologicalcontactoxidationpond,theverticalflowsedimentationtank,disinfectiontank,sludgepumpingstation,sludgethickeningtank,dewateringroometc..Finally,intheprocessofdesignproblemsarediscussed,wroteanessay;andcompletedaperiodofEnglishtranslationwork.Keywords:UASB;brewerywastewater;biologicalcontactoxidation;sludgetreatmentI目录第一篇设计说明书.......................................................................................................1第一章概述...................................................................................................................11.1毕业设计题目...................................................................................................11.2毕业设计目的及意义.......................................................................................11.3毕业设计任务...................................................................................................11.4设计资料...........................................................................................................21.4.1城市概况................................................................................................21.4.2气候条件................................................................................................21.4.3水文条件................................................................................................21.4.4处理站进出水水质................................................................................21.4.5其他资料................................................................................................31.5设计依据...........................................................................................................31.6工程建设的必要性和工程内容.......................................................................41.6.1工程建设的必要性................................................................................41.6.2工程建设的内容....................................................................................4第二章处理站工艺确定...............................................................................................52.1规模与处理程度的确定...................................................................................52.1.1进水水质................................................................................................52.1.2出水水质................................................................................................52.1.3处理程度确定........................................................................................52.2水处理方案的选用原则...................................................................................62.3水处理工艺流程的确定...................................................................................62.3.1待选方案的确定....................................................................................62.3.2方案比选................................................................................................82.4泥处理工艺流程的确定.................................................................................102.5处理站的工艺流程.........................................................................................11第三章处理站设计.....................................................................................................123.1水处理系统设计.............................................................................................123.1.1粗格栅..................................................................................................123.1.2提升泵房..............................................................................................133.1.3细格栅..................................................................................................14II3.1.4调节池......................................................
