ABR刘贞培1,2, 伍健东1,2, 周兴求1,2(1.华南理工大学环境科学与工程学院,广东广州510006;2.华南理工大学工业聚集区污染控制与生态修复教育部重点实验室,广东广州510006)   : 采用厌氧折流板反应器(ABR)作为产甲烷相反应器,开展了处理食品废水的中试研究。分析了调试运行期间的控制因素,考察了反应器的启动运行情况、出现酸化后的调节恢复方法以及稳定运行阶段的除污效果。实际运行表明:当以ABR作为产甲烷相反应器时,对食品废水具有较好的处理效果,对COD、SS、色度的去除率分别为(64%~81%)、(49%~77%)、(30%~69%);ABR反应器出现较长时间的酸化后,可以通过投加化学药剂、减小处理量、添加新鲜污泥等手段进行恢复,在保证适宜的碱度、VFA、pH条件下,能完全恢复反应器的处理性能。  : 产甲烷相反应器; 厌氧折流板反应器; 食品废水:X703  :A  :1000-4602(2010)09-0022-04PilotTestofAnaerobicBaffledReactorasMethanogenic-phaseReactorforTreatmentofFoodWastewaterLIUZhen-pei1,2, WUJian-dong1,2, ZHOUXing-qiu1,2(1.CollegeofEnvironmentalScienceandEngineering,SouthChinaUniversityofTechnology,Guangzhou510006,China;2.KeyLabofPollutionControlandEcosystemRestorationinIndustryClustersMinistryofEducation,SouthChinaUniversityofTechnology,Guangzhou510006,China)  Abstract: Pilottestofusinganaerobicbaffledreactor(ABR)asmetheanogenic-phasereactorfortreatmentoffoodwastewaterwasstudied.Controllingfactorsinthecommissioningwereanalyzed,andthestartupofABR,therecoverymethodsafteroccurrenceofacidificationandtheremovalefficiencyofcon-taminantsinthestablephasewereinvestigated.Theoperationresultsshowthatasthemetheanogenic-phasereactor,theABRiseffectiveintreatingfoodwastewater.TheremovalratesofCOD,SSandcolorare64%to81%,49%to77%and30%to69%respectively.Afteralongperiodoccurrenceofacidifi-cation,therecoverymethodssuchasdosingchemicals,decreasingtheloadandaddingfreshsludgecanbeadopted.Thetreatmentperformanceofthereactorcanberecoveredwhilemaintainingsuitablealkalin-ity,VFAandpH.
