处理柠檬酸生产废水的MIC反应器的快速启动_吴建华处理柠檬酸生产废水的MIC反应器的快速启动吴建华,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)摘要: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。关键词:柠檬酸生产废水;多级内循环厌氧反应器;启动;颗粒污泥中图分类号:X703文献标识码:C文章编号: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,thevolumeloadingoftheinfluentcanreachabou
