某工业用酶制剂废水处理工艺设计设计说明书

学号:毕业设计（届）题目：某生物工程有限公司工业用酶制剂废水处理工艺设计学生：学院（系）：专业班级：校内指导教师：专业技术职务：校外指导老师：专业技术职务：摘要：本设计为某酶制剂废水处理设计。设计程度为初步设计。酶制剂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。该酶制剂废水的处理水量为1000m3/d,不考虑远期发展。原污水中各项指标为：COD浓度为15000mg/L，SS浓度为500mg/L，氨氮浓度为20mg/L。要求处理后的排放水要严格达到国家三级排放标准。经分析知该处理水质属易生物降解又无明显毒性的废水，可采用两级生物处理以使出水达标。一级处理主要采用物理法，用来去除污水中的悬浮物质和无机物。二级处理主要采用生物法,包括厌氧生物处理法中的UASB法和好氧生物处理法中的SBR法，可有效去除污水中的BOD、COD。整个工艺具有总投资少，处理效果好，工艺简单，占地面积省，运行稳定，能耗少的优点。关键词：酶制剂废水处理高浓度有机废水UASB法SBR法Abstract：Thisdesignisoneenzymepreparationwatertreatment.Thedegreeofthedesignisinapreliminaryphase.Themaindistinguishingfeatureoftheenzymepreparationwastewateristhatitcontainsthemassiveorganicmatters,soitbelongstothehighconcentrationorganicwastewater,thereforeitsbiochemicaloxygendemandisalsohigh.Thewaterwhichneedstotreatmentinthetreatmentplantis1000dm/3,regardlessofthespecifiedfuturedevelopment.Varioustargetintherawwastewateris:theconcentrationofCODis15000mg/L,theconcentrationofSSis500mg/L,theconcentrationofammoniais200mg/L.Thewastewatercouldbetreatedtomeetthethirdlevelofthenationaldischargestandard.Aftertheanalysis,thequalityofthisprocessingwaterbelongstothewastewaterthateasybiologydegradeandnothavetheobviouspoison,couldusetwolevelsofbiologicaltreatmentstotreatthewater.Firstlevelofprocessingmainlyusesthephysicalmethods,whichremovesthesuspendedsolidsandtheinorganicsubstanceinthewater.Secondlevelsofprocessingmainlyusesthebiologymethods,consistsofUASBofdemandoxygenbiologymethodsandSBRofanaerobicoxygenbiologymethods,whichcouldremoveBOD,CODinthewastewater.Theentiretechnologicalprocesshavethecharacteristicsoflowerinvestment,goodtreatmenteffect,easytechnologyprocess，usingsmallarea,runningsteady,andconsuminglowerenergy.Keyword:EnzymepreparationwastewatertreatmentHighconcentrationoforganicwastewaterUASBSBR目录1总论.................................................................................................................11.1工程概况......................................................................................................................11.2设计资料......................................................................................................................11.3设计依据......................................................................................................................11.4设计内容及要求..........................................................................................................11.5处理方案的确定..........................................................................................................21.5.1基本工艺确定...................................................................................................21.5.2预处理工艺选择...............................................................................................21.5.3厌氧处理工艺选择...........................................................................................21.5.4好氧处理工艺选择...........................................................................................21.7方案的可行性分析.......................................................................错误!未定义书签。1.7.1调节沉淀池........................................................................错误!未定义书签。1.7.2化学沉淀池........................................................................错误!未定义书签。1.7.3UASB反应器........................................................................错误!未定义书签。1.7.4SBR反应池..........................................................................错误!未定义书签。1.8废水设计处理效果........................................................................错误!未定义书签。2工艺计算..........................................................................错误!未定义书签。2.1格栅的设计...................................................................................错误!未定义书签。2.1.1设计说明............................................................................错误!未定义书签。2.1.2设计计算............................................................................错误!未定义书签。2.2调节池的设计...............................................................................错误!未定义书签。2.2.1设计说明............................................................................错误!未定义书签。2.2.2设计计算............................................................................错误!未定义书签。2.3一次污水泵站的设计...................................................................错误!未定义书签。2.3.1设计说明............................................................................错误!未定义书签。2.3.2集水井................................................................................错误!未定义书签。2.3.3污水泵计算........................................................................错误!未定义书签。2.3.4引水筒的设计计算............................................................错误!未定义书签。2.4化学沉淀池的设计.......................................................................错误!未定义书签。2.4.1设计说明............................................................................错误!未定义书签。2.4.2设计计算............................................................................错误!未定义书签。2.5UASB的设计...................................................................................错误!未定义书签。2.5.1设计说明...................
