生物制药废水处理

辽宁科技大学本科生毕业设计第I页某生物制药厂污水处理站的设计摘要本设计是处理量为3400m3/d的生物制药废水工艺设计。制药废水的有机物浓度高，成分复杂，含有石油类、胺类、酸类、破乳剂等污染物。此外，水中还含有难以降解的大分子苯环物质和浓度很高的SO42-，水质为CODcr4000~5000mg/L，BOD5为2500~3000mg/L，SS为2000~2500mg/L，pH值为8~10。利用UASB与SBR组合工艺的处理可以达到去除该废水中有机物的目的。本生物制药废水处理设计流程为：废水经过格栅去除浮渣，出水收集到集水井，再用泵提升至澄清池，澄清池的出水经泵提升进入UASB反应器进行厌氧处理，再经竖配水井，将泥水分离后的上清液进入SBR反应器，在SBR反应器中进行好氧处理。本设计的建设投资为1141万元，处理成本为1.82元/m3。经该工艺处理后的出水水质为CODcr85mg/L，BOD590mg/L，SS68mg/L，pH值6~9，达到国家《污水综合排放标准》（GB8978-1996）生物制药废水排放的二级标准。关键词：UASB+SBR工艺；生物制药污水；活性污泥处理辽宁科技大学本科生毕业设计第II页AbiologicalpharmaceuticalfactorysewagetreatmentplantdesignAbstractPharmaceuticalwastewaterofhighconcentrationorganicmatter,complicatedcomposition,containoil,amine，acids,andpollutantssuchasdemulsifier.Inaddition,thewateralsocontainhardtodegrademacromolecularmaterialandhighconcentrationsofbenzeneringofwaterquality,SO42-forCODcr4000~5000mg/L,BOD5for2500to3000mg/L,SSfor2000to2500mg/L,pHvaluefor8to10.WithUASBandcombinationofSBRprocesstoremovethewastewatertreatmentcanachievethepurposeoforganicmatter.Thebiologicalpharmaceuticalwastewatertreatmentprocessdesignfor:wastewaterafterremovingscum,collectwatergrilletocollect,thenusetopumpwaterWellsuptoclarifythepool,thepoolofwaterpumpcleartheascensionintotheUASBreactoronanaerobictreatment,thenthroughshaftwithWells,willspateseparationofafterqingliquidintothereactor,thereactorinSBRofaerobictreating.Thedesignoftheconstructioninvestmentis11.41millionyuan,processingcostis1.82yuan/m3.AfterthetreatmenttechnologyofeffluentwaterforCODcrafter85mg/L,BOD590mg/L,SS68mg/LpHv,alueof6~9,thesewagetothenationalcomprehensivedischargestandard(GB8978-1996)biologicalpharmaceuticalwastewaterdischargeofthesecondarystandard.Keywords：UASB+SBRprocess；Biologicalpharmacysewage；activatedsludge辽宁科技大学本科生毕业设计第III页目录摘要..................................................................................................................IAbstract................................................................................................................II1绪论...................................................................................................................11.1项目背景..........................................................................................................................11.2设计依据..........................................................................................................................11.3设计原则..........................................................................................................................11.4设计内容..........................................................................................................................22设计水质及设计要求.......................................................................................32.1废水的来源......................................................................................................................32.2废水水质..........................................................................................................................32.3处理要求..........................................................................................................................33工艺选择...........................................................................................................53.1处理方法简介..................................................................................................................53.1.1方案一.......................................................................................................................53.1.2方案二.......................................................................................................................63.1.3方案三.......................................................................................................................73.2方案选择..........................................................................................................................84工艺设计.........................................................................................................104.1各构筑物去除率............................................................................................................104.2构筑物设计及工艺说明................................................................................................104.2.1格栅.........................................................................................................................104.2.2调节池.....................................................................................................................114.2.3集水池.....................................................................................................................124.2.4水利循环澄清池.....................................................................................................124.2.5UASB反应器.......................................................................................................134.2.6三相分离器.............................................................................................................144.2.7配水井..................................................
