第6卷第11期2012年11月环境工程学报ChineseJourna1ofEnvironmentalEnzineerinVO1.6.NO.11NOV.2012水解酸化-改良UASB工艺处理玉米酒精废水于鲁冀王惠英陈涛,邵玉敏孔德芳,范佳琦,(1.郑州大学水利与环境学院,郑州450002;2.郑州大学环境技术咨询工程公司,郑州450002;3.郑卅I大学环境政策规划评价研究中心,郑州450002;4.华北水利水电学院环境与市政工程学院;郑州450002)摘要采用一种新的工艺技术方法即水解酸化一改良UASB工艺处理玉米酒精废水。结果表明,在改良UASB运行60d顺利启动完成后,进水COD在5470~7910mg/L之间,TN在70~107mg/L之间,TP在115~187mg/L之间,ss在864~1490mg/L之间的条件下,水解酸化对COD和ss的去除率分别达50%和51%,NH一N经过水解酸化后升高。改良UASB对COD的去除率达80%,对NH一N、TN和TP也有一定去除,去除率分别为12%、17%和20%,经过水解酸化及改良UASB处理利于后续好氧处理。关键词玉米酒精废水水解酸化改良UASB中图分类号X703文献标识码A文章编号1673.9108(2012)11—3970.05Treatmentofcornalcoholwastewaterusinghydrolysisacidification-improvedUASBYuLujiWangHuiying,ChenTao一ShaoYuminKongDefang,FanJiaqi'。(1CollegeofWaterConservancy&EnvironmentalEngineering,ZhengzhouUniversity,Zhengzhou450002,China:2.ZhengzhouUniversityEnvironmentalTechnologyandConsultingCompany,Zhengzhou450002,China;3.ZhengzhouUniversityResearchCenterforEnvironmentalPolicyplanningandAssessment,Zhengzhou450002,China;4.InstituteofEnvironmental&MunicipalEngineering,NorthChinaUniversityofWaterResourcesandElectricPower.Zhengzhou450002.China)AbstractHydrolysisacidification—improvedUASBprocesswasadoptedtotreatcornalcoholwastewater.TheresultsshowedthattheremovalratesofCODandSSreached50%and51%.respectivelyafterthehydroly—sisacidificationprocess,whentheimprovedUASBreactorwassuccessfullylaunchedafter60doperationandtheCOD,TN,TPandSSeoneentratinonsoftheinfluentwaterwere5470~7910mg/L.70~107mg/L.115~187mg/Land864~1490mg/L,respectively;however,NH3一Nconcentrationincreasedafterhydrolysisacidifi—cation.Underthesameexperimentalconditions.theremovalrateofCODwasupto80%afterimprovedUASBprocess,NH3一N,TNandTPwerealsoremovedpartly,andthecorrespondingremovalrateswere12%,17%and20%,respectively.Hydrolysisacidification—improvedUASBprocesswasbeneficialtothesubsequentaerobictreatment.Keywordscornalcoholwastewater;hydrolysisacidification;improvedupflowanaerobicsludgeblanket酒精行业的污染以水污染最为严重,酒精生产废水包括蒸馏发酵后排出的醪糟、生产设备的洗涤水和冲洗水以及蒸煮、糖化、发酵、蒸馏工艺的冷却水等,它具有粘度大、pH值低、温度高、有机物和悬浮物含量高的
