黄酒废水处理设计VIP免费

摘要本设计为某黄酒废水处理设计,设计程度为初步设计。黄酒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。该黄酒废水处理厂的处理水量为12000m3/d,高浓度废水3500m3/d，低浓度废水1250m3/d，不考虑远期发展。原污水中各项指标均非常高，严重超出国家标准，故要求处理后的排放水要严格达到国家一级排放标准。又因为高低浓度废水的物质浓度相差较大，且水量也有很大差异，故将高低浓度废水分开处理，之后再混合。本设计采用厌氧好氧相结合的方法降低污水中的有机污染物。本设计工艺主要是用UASB工艺和UCT工艺处理黄酒废水的。其流程为：黄酒废水（高）→格栅→调节池→UASB→集水池→UCT→辅流式二沉池。设计中对UASB、UCT工艺所涉及到的设施等进行了严密计算，在预算方面充分考虑到各方面可能涉及到的花费。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：黄酒废水处理；UASB处理；UCT工艺AbstractThegraduateworkisaprimarydesignforyellowwinewastewatertreatment.Themaincharacteristicofthericewinewastewateristhatitishighconcentrationorganicwastewatercontaininglargeamountsoforganicmatters.Soitneedslargeamountofoxygeninbiochemicalreaction.Thetreatmentplantofthericewinewastewatercantreatwaterof12000m3/d,highconcentrationwastewaterof3500m3/d,lowconcentrationwastewaterof1250m3/d,itdoesn'tconsideroflong-termdevelopment.Eachindexoftheoriginalsewageisallveryhigh,exceedsnationalstandardseriously.Thelevelofthedischargewateraftertreatmentdemandstoreachgrade1nationalstandardstrictly.Becauseoflargedifferencebetweenhighconcentrationwastewaterandlowconcentrationwastewaterinmaterialconcentration,theywillbehandledseparately,andthenmixedtogether.Thisdesignemployedtheanoxia-oxidationmethodtoreducetheorganicpollutantsofthewastewater.,usingUASBandUCT.Itsprocessis:Ricewinewastewater(high)-grilling–regulatingponds-UASB-Collectingtank-UCT-thesecondpondofauxiliarystreaming.ThedesigndidatightcalculationontheestablishmentthatinvolvedinUSABandUCTprocess,italsohastakenthebudgetaryonmanytermsintoconsideration.Thewholeprocesshastheadvantagesoflessinvestment,goodeffectofthetreatment,simpleprocess,coverslittlearea,stableoperationandlessenergyconsumption.Keywords：ricewinewastewatertreatment;UASBprocessing;UCTprocess目录1绪言.............................................................................................................12设计依据、原则和范围.............................................................................32.1设计依据................................................................................................32.2设计规范................................................................................................32.3设计原则................................................................................................43工程规模、进水水质及处理程度.............................................................53.1工程内容................................................................................................53.2进水水量、水质....................................................................................53.3排放标准................................................................................................54废水处理工艺的确定.................................................................................74.1废水特性................................................................................................74．2主要废水处理工艺的比较与选择...............
