ABR工程设计的要点分析_周华

226　　给水排水　Vol.35　增刊　2009ABR工程设计的要点分析周　华(环境保护部华南环境科学研究所,广州　510655)　　摘要　针对印染废水的特性和已有印染废水生化处理工艺在工程应用中存在的问题分析的基础上,提出ABR工艺方案,成功应用于印染废水的厌氧处理工段,保证了稳定的COD去除效率和脱色效果。通过分析ABR反应器的运行规律,总结出HRT、反应器内的水力流态优化是ABR设计成败的关键。关键词　印染废水　ABR　水力流态　HRTAnalysisofABR'sengineeringdesignconsiderationZhouHua(SouthChinaInstituteofEnvironmentalSciences,MEP,China,MinistryofEnvironmentalProtection,Guangzhou510655,China)Abstract:Basedonthecharacteristicsofprintingdyeingwastewaterandanalysisoftheexistingproblemofapplicationinprintingdyeingwastewater'sbiologicaltreatmentprocess.ProposedABRprocessscheme,itshasbeenusedonanaerobicwastewatertreatmentofprintingdyeingwastewater,butalsoensuredtheremovalrateofCODanddecolorizingeffectarestable.Withana-lyzingoperationregulationsofABRreactor,thearticlehasconcludedengineeringdesignconsidera-tion-HRTandtheoptimizationofflowpatternofwaterpowerinreactor.Theyarethekeyforsuc-cessfulofABRdesign.Keywords:Printinganddyeingwastewater;Anaerobicbaffledreactor(ABR);Flowpatternofwaterpower;Hydraulic
