MIC吴建华, 刘 锋, 冯俊强, 蒋京东, 马三剑(苏州科技学院环保应用技术研究所,江苏苏州215011) : 采用自行设计研制的多级内循环厌氧反应器(MIC反应器)处理柠檬酸生产废水,以城市污水处理厂消化池厌氧污泥为接种污泥,采用逐步提高进水负荷的方法启动反应器。经过2个多月的调试运行,反应器的泥床区内已充满颗粒污泥,进水容积负荷达8kgCOD/(m3·d)左右,对COD的去除率稳定在85%左右,实现了MIC反应器的快速成功启动。 : 柠檬酸生产废水; 多级内循环厌氧反应器; 启动; 颗粒污泥:X703 :C :1000-4602(2008)05-0102-03RapidStart-upofMICReactorforCitricAcidWastewaterTreatmentWUJian-hua, LIUFeng, FENGJun-qiang, JIANGJing-dong, MASan-jian(InstituteofAppliedTechnologyofEnvironmentalProtection,SuzhouUniversityofScienceandTechnology,Suzhou215011,China) Abstract: Multi-internal-circle(MIC)anaerobicreactorwhichwasself-designedandmanufac-turedwasappliedtotreatthecitricacidwastewater.Usinganaerobicsludgefromdigestiontankofmunic-ipalwastewatertreatmentplantasseedingsludge,thestart-upofthereactorwascarriedoutbyincreasingtheinfluentloadingstepbystep.Afterthecommissioningoperationformorethantwomonths,thesludgebedzoneofthereactorisfullofgranularsludge,thevolumeloadingoftheinfluentcanreachabout8kgCOD/(m3·d),andtheCODremovalrateisstablyabout85%.Rapidstart-upofthereactorisre-alizedsuccessfully.
