碳酸饮料废水处理毕业设计

武汉科技大学本科毕业设计I摘要本设计为碳酸饮料厂废水处理初步设计。本文分析了碳酸饮料厂废水处理处置的相关工艺方法，提出了UASB+SBR的组合工艺流程。碳酸饮料厂废水水质的主要特点是含有大量的有机物，属高浓度有机废水，故其生化需氧量也较大。UASB（Up-flowAnaerobicSludgeBed/Blanket）工艺是由荷兰Lettinga教授于1977年发明的一种污水处理工艺，是处理有机废水比较常用的一种工艺。它自70年代以来得到不断改进和发展，它在处理高浓度有机废水方面与其它生物处理相比具有成本低、反应器负荷高、体积小，占地少、运行简单、规模灵活、二次污染少等强大优势。SBR则与传统污水处理工艺不同，SBR技术以时间分割的操作方式替代了空间分割的操作方式，非稳定生化反应替代了稳态生化反应，静置理想沉淀替代了传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作，该技术的核心是SBR反应池，该池集均化、初沉、生物降解、二沉等功能于一池，无污泥回流系统。该工艺为碳酸饮料行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：碳酸饮料废水；UASB；SBR武汉科技大学本科毕业设计IIAbstractThepreliminarydesignofawastewatertreatmentplantforaCarbonateddrinkswasshowedinthispaper.TherelevantprocessofthewastewatertreatmentandacombinedprocessofUASB+SBRdisposalwereproposedinthisarticle.Themaincharacteristicsofthewastewaterwerelargequantitiesoforganicmaterials,highconcentrationsoforganicpollutionsandhighCOD.UASB(Up-flowAnaerobicSludgeBed/Blanket)technologywasakindofmethodofsewagetreatmentinventedbyLettinga,aHollandprofessorin1977.ItwasaverypopularprocessinorganicwastewaterTreatment.Withcontinuouslyimprovinganddevelopingsince70s,itshowedmanyadvantagesinthetreatmentofhighconcentrationorganicbiologicalwastewatercomparedwithotherorganicbiologicaltechnology,suchaslowercosting,higherloading,smallervolume,lessfieldusing,simplertobeoperated,moreflexiblemonumentandlesssecondarypollution.SBRwasmuchdifferentfromtraditionalsewagetreatmenttechnologythatthetimedivisionmodeinsteadofthespacesegmentationmode,Unsteadybiochemicalreactioninsteadofthebistablebiochemicalreaction,StaticidealsettlinginsteadofthetraditionaldynamicprecipitationintheSBRoperation.Runninginorderandoperatingintermittentlywasitsmaincharacteristic.ThecoreofthistechnologywastheSBRreactionpool,whichwascombiningwithhomogenizing,firstsedimentation,biologicaldegradation,secondarysedimentationandotherfunctionsbutwithoutasludgereturnsystem.Thewastewatertreatmentprocessforcarbonatedbeverageindustryprovidesafeasibleway,hasthegoodeconomicbenefit,environmentalbenefitandsocialbenefit.Keywords:Carbonatedbeveragewastewater;UASB;SBR武汉科技大学本科毕业设计III目录绪论........................................................................................................................................11工程概况..............................................................................................................................21.1设计任务...................................................................................................................21.1.1污水来源和特点............................................................................................21.1.2处理规模........................................................................................................21.1.3污水处理系统要求........................................................................................21.2污水水质及处理程度...............................................................................................21.2.1设计进出水水质............................................................................................21.2.2处理程度的确定............................................................................................31.3设计原则...................................................................................................................31.4工艺方案的比较与选择...........................................................................................32污水处理工艺设计与计算..................................................................................................62.1格栅...........................................................................................................................62.1.1设计说明........................................................................................................62.1.2格栅计算........................................................................................................62.2集水井.......................................................................................................................82.2.1设计说明........................................................................................................82.2.2设计计算........................................................................................................92.3沉砂池.......................................................................................................................92.3.1设计参数......................................................................................................102.3.2设计计算......................................................................................................102.4调节池.....................................................................................................................122.4.1参数选择......................................................................................................122.4.2尺寸的计算..................................................................................................132.4.3产泥量..........................................................................................................13武汉科技大学本科毕业设计IV2.4.4进水系统........................................
