啤酒废水处理工艺VIP免费

I摘要随着人民生活水平的不断提高，我国的啤酒工业发展迅速，啤酒产量有了较大幅度的增长，已成为世界五大啤酒生产国之一。至目前为止全国啤酒年产量超过2500万吨，居世界首位。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，对几种常见的处理利用技术进行了比较，得出结论：单一的处理和利用技术不能从根本上解决啤酒废水的污染问题，只有将多种技术结合使用，才能达到经济效益和环境效益的统一。此外啤酒废水中BOD5/CODcr值高，在50％及以上，非常有利于生化处理。同时生化处理与物理法、化学法相比较；一是处理工艺比较成熟；二是处理效率高，CODcr、BOD5去除率高，一般可达80％~90％以上；三是处理成本低（运行费用省）；经过对各种处理工艺的对比，最终选择UASB+CAST工艺作为处理工艺。该处理工艺具有结构紧凑简洁，运行控制灵活，抗冲击负荷，污泥量小等特点，实践表明该组合工艺处理性能可靠，投资少，运行管理简单的特点。为啤酒工业废水处理提供了一条可行途径。具有良好的经济效益、环境效益和社会效益。关键词：啤酒废水，UASB,CASTIIIAbstractWiththecontinuousimprovementoflivingstandards,China'sbeerindustryisdevelopingrapidly,beerproductionhasincreasedgreatly,hasbecomeoneoftheworld'sfivelargestproducerofbeer.Sofarthenationalbeeroutputmorethan25000000tons,rankingfirstintheworld.Theorganicmattercontentinbeerwastewaterishigh,suchasdirectemissions,notonlypollutetheenvironmentbutalsoreducethebeerindustryrawmaterialutilizationratio,therefore,formanyscholarsandmanufacturersofbeerwastewatertreatmentandutilizationoftechnology,severalcommontreatmentandutilizationtechnologyarecompared,theconclusion:technologycannotsolvetheprocessingandutilizationofsinglebeerwastewaterpollutionproblemfundamentally,onlythecombinationofvarioustechniques,inordertoachievetheunityofeconomicbenefitsandenvironmentalbenefits.Inaddition,thevalueofBOD5/CODcrofbrewerywastewaterishigh,inthe50%andabove,isveryconducivetobiochemicaltreatment.Atthesametime,biochemicaltreatmentandphysicalmethod,chemicalmethodarecompared;oneisprocessingtechnologymoremature;twoisthehightreatmentefficiency,highremovalrateofCODcr,BOD5,generallyupto80%~90%;threeisthelowprocessingcost(cost);aftercomparingthevarioustreatmentprocesses,thefinalselectionofUASB+CASTtechnologyasaprocess.Thisprocesshasacompactandsimplestructure,flexiblecontrol,shockresistance,smallamountofsludgecharacteristics,practiceshowsthatthecombinedprocessofreliableperformance,lowinvestment,simpleoperationandmanagementcharacteristics.Providesafeasiblewayforbeerindustrialwastewatertreatment.Withgoodeconomicbenefits,environmentalbenefitsandsocialbenefits.Keywords:beerwastewater,UASB,CASTIIIII目录1.绪论...............................................................12.设计资料...........................................................22.1原始数据......................................................22.2气象资料......................................................23.工艺的比较及选择...................................................33.1啤酒废水处理工艺..............................................33.1.1酸化—SBR法处理啤酒废水................................33.1.2UASB—好氧接触氧化工艺处理啤酒废水.....................43.1.3新型接触氧化法处理啤酒废水..............................43.1.4生物接触氧化法处理啤酒废水..............................43.1.5内循环UASB反应器＋氧化沟工艺处理啤酒废水................63.1.6UASB+SBR法处理啤酒废水..................................
