毕业设计（论文）中文摘要皮革制备厂的工业废水处理设计摘要：皮革废水成分非常复杂、有机物浓度较高，含有一定量的无机物及皮渣、毛类、泥砂等有害物质。BOD、COD、氨氮、硫化物、悬浮物等也非常高，是较难5Cr处理的工业废水。针对其以上特点及废水排放要求，采用 Carrousel 氧化沟处理工艺。为了使工艺流程简单且不影响处理效果，设计中采取中格栅和污水提升泵房,细格栅和混凝沉淀池合建在一起。设计结果表明，卡鲁塞尔氧化沟工艺造价低、运行稳定、自动化程度高、管理方便，并且有一定的脱氮除磷效果，对有机物的去除率很高，BOD 去除率约 94%，5COD 去除率高达 96%以上，悬浮物去除率约 75%,硫化物去除率达 99%，油脂类去Cr除率为 99%以上。处理后出水水质良好，可以达到 GB18918-2002 二级标准。关键词：皮革废水氧化沟脱硫除铬毕业设计（论文）外文摘要TitleDesignofindustrialwastewatertreatmentofleatherpreparationplantAbstractLeatherwastewaterisakindofhighconcentratedoforganicwastewaterofverycomplicatedcomposition,whichcontainsacertainquantityofinorganicsubstanceandsomeharmfulmaterialssuchasskinslag,hairtype,sandsandothers.BOD,COD,ammonianitrogen,sulfideandsuspendedmatter5Crarealsoveryhigh,whichisdifficulttotreat.Accordingtotheabovecharacteristicsandwastewaterdischargerequirements,IchosetheCarrouseloxidationditchprocess.Inordertomaketheprocesssimpleranddoesnotaffectthetreatmenteffect,inthedesign,Itakethegrilleandsewageascensionpumproom,thingrilleandcoagulationtrapsbuilttogether.Thedesignresultshowsthatthecarrouseloxidationditchprocesshasalotofgoodpoints,suchaslowcost,stableoperation,ahighdegreeofautomationandconvenientmanagement.Italsohasdenitrificationandphosphorousremovaleffectandhighremovalrateoforganicmatter,theremovalrateofBODis94%,theremovalrateofCODisashighas96%above,5Crtheremovalrateofsuspendedsolidsisabout75%,andtheremovalrateofsulfideandoilis99%above.Thetreatedwastewaterisgood,whichcanachieveGB18918—2002secondarystandard.Keywords：leatherwastewateroxidationditchdesulfurizationchromiumremovement1绪论………………………………………………………………………11.1皮革废水的来源……………………………………...
