某啤酒厂污水处理站工艺设计

I某啤酒厂污水处理站工艺设计摘要啤酒废水中有机物含量较高，如直接排放，既污染环境又降低啤酒工业的原料利用率。为此，许多学者和厂家对啤酒废水的处理和利用技术进行研究。本文根据前人的研究成果综述了啤酒废水的处理和利用现状，结合啤酒废水自身的特性，根据进水水质和排放标准，通过对几种处理工艺的比较，确定污水处理采用UASB+CASS的工艺。对格栅、调节池、UASB池、CASS池、污泥浓缩池等进行了正确的设计和计算。并参考经验设计参数进行UASB+CASS的处理工艺设计，采用UASB+CASS工艺处理高浓度有机废水，不但使处理流程简洁，节省了运行管理费用，同时还可以回收在处理过程中所产沼气作为能源的利用，以便我为进一步探讨效益资源型处理技术提供借鉴。关键字啤酒工业；废水处理；UASB；CASSIIThecontrolsystemdesignof200,000t/yearbreweryproductionwastewaterAbstractBeinghighlevelsoforganicpollutants,brewerywastewatermaynotonlyleadtoenvironmentalpollution,butalsodecreasetheutilizationratioofrawmaterialusedinbeerproduction.Therefore,manyscholarsandbrewerieshavepaidmuchattentiontodevelopingnewtechniquesfortreatingandmakinguseofbrewerywastewater.Thispapermakesacomparisonamongvariousnewtechniquesonthebasisofanalyzingthesourcesandcharacteristicsofbrewerywastewater.Throughseveraltreatmentsstudying,Imakethebestwaytotreatmentthewastewaterfrombrewery—UASB+CASS.FromthisliteraryyoucanachievealotofwaysaboutUASB+CASS.Thetreatmentofcalculation,forexample,gridaccommodator;regulationtank;UASBtank;CASStank;concentratemudpoolandmakeadetailedexplanationforthemainbuilding.UsedUASBtreatingwastewaterofthebreweryismaintaintheanaerobicgranularsludge.Withthisway,notonlymaketheprocessflowsimple,butalsosaveoperatingcosts,whilereducingwastewaterconcentration,methanecanberecycledintheprocessoftheproductionasenergyuse,sothatIcanprovideareferencetofurtherinvestigatetheeffectivenessofresource-basedprocessingtechnology.Keywordsbreweryindustry；wastewatertreatment；UASB；CASSIII目录第一部分设计说明书...............................................................11.概述..........................................................................11.1工程概况.................................................................11.2设计依据.................................................................11.3任务书的主要内容和要求....................................................21.3.1主要内容............................................................21.3.2设计要求............................................................22.原水的水质和水量及处理要求.....................................................32.1原水水量与水质............................................................32.1.1建设规模............................................................32.1.2设计原水水质指标....................................................32.2处理要求.................................................................33.工艺选定......................................................................43.1水质分析.................................................................43.2啤酒废水处理的流行工艺....................................................43.2.1好氧处理工艺........................................................43.2.2水解—好氧处理工艺..................................................43.2.3厌氧—好氧联合处理技术..............................................43.3适用于啤酒废水处理的工艺比较..............................................54.工艺比较......................................................................54.1比较工艺的选择及叙述......................................................54.2方案比较.................................................................64.2.1两个方案的主要构筑物比较表..........................................64.2.2两个方案的主要优缺点................................................74.3处理方案的确定............................................................74.3.1污水处理流程.......................................................74.3.2污泥处理流程.......................................................75.选定工艺的设计................................................................85.1粗格栅...................................................................85.1.1构筑物..............................................................85.1.2主要设备............................................................85.2调节池...................................................................85.2.1构筑物..............................................................85.2.2主要设备............................................................85.3UASB反应池...............................................................95.3.1构筑物..............................................................9IV5.3.2主要设备............................................................95.4CASS反应池...............................................................95.4.1构筑物..............................................................95.4.2主要设备...........................................................105.4混凝沉淀池..............................................................105.5污泥浓缩池..............................................................106.厂区的相关布置...............................................................116.1平面布置................................................................116.1.1各处理单元构筑物的平面布置.........................................116.1.2辅助建筑物.........................................................116.1.3平面布置原则.......................................................116.2高程布置................................................................127.工程投资概算.................................................................127.1估算范围及依据...................
