A/O脱氮工艺的控制策略和应用性研究马　勇1　王淑莹2　王晓莲2　彭永臻1,2(1.哈尔滨工业大学市政与环境工程学院,哈尔滨150090;2.北京工业大学环境与能源工程学院,北京100022)摘　要　根据A/O脱氮工艺的运行状况和影响因素,提出了应用在线传感器连续测定曝气池中DO浓度、氨氮浓度和硝酸氮浓度,并据此调节供氧强度、内循环回流量、有机碳源的投加以及硝化区和反硝化区的大小,这是保证A/O脱氮工艺良好处理效果的重要控制策略和思想。同时对近年来国外A/O脱氮工艺自动控制的应用及研究进行了简单的回顾。关键词　A/O脱氮工艺　在线传感器　DO浓度　自动控制ControlstrategiesandapplicationresearchofA/OnitrogenremovalprocessMaYong1　WangShuying2　WangXiaolian2　PengYongzhen1,2(1.SchoolofMunicipalandEnvironmentalEngineering,HarbinInstituteofTechnology,Harbin150090;2.SchoolofEnvironmentalandEnergyEngineering,BeijingPolytechnicInstitute,Beijing100022)Abstract　AccordingtooperationstatusandeffectfactorsofA/Onitrogenremovalprocess,inthisarticle,im-portantcontrolstrategiesandideaswhichusingon-linesensorscontinuouslymeasuredissolvedoxygenconcentration,ammoniumconcentrationandnitrateconcentrationinaerationbasinandbasedonthemtoadjustaerationintensity,in-ternalnitraterecycle,substratedosingandtheratioofnitrificationvolumeanddenitrificationvolumetoprotectgoodef-fluentareintroduc
