SBR高大文1, 彭永臻2, 王淑莹2(1.哈尔滨工业大学市政环境工程学院,黑龙江哈尔滨150090;2.北京工业大学环境与能源工程学院,北京100022) : 以实际豆制品生产废水为处理对象,研究了传统固定时间控制和实时控制两种模式下SBR反应器的短程硝化反硝化效果。结果显示,实时控制下的硝化速率和反硝化速率分别为按固定时间控制时的1.40倍和1.86倍,硝化和反硝化时间则比传统运行方式分别缩短了60min和25min。因此,可采用ORP和pH值实时控制SBR法的短程硝化反硝化过程,它不仅可以合理分配曝气和搅拌时间,而且还能提高硝化速率并缩短反应时间,达到了降低运行成本的目的。 : 豆制品废水; SBR; 短程硝化反硝化; 实时控制:X703.1 :A :1000-4602(2004)06-0009-03Short-cutNitrificationandDenitrificationinSBRunderDifferentControlModesGAODa-wen1, PENGYong-zhen2, WANGShu-ying2(1.SchoolofMunicipalandEnvironmentalEngineering,HarbinInstituteofTechnology,Har-bin150090,China;2.SchoolofEnvironmentalandEnergyEngineering,BeijingUniversityofTechnology,Beijing100022,China) Abstract: Nitrogenremovalbymeansofshort-cutnitrificationanddenitrificationunderrealtimeandfixedtimecontrolmodeswasstudiedinsequencingbatchreactor(SBR)fedwithsoybeanwastewater.There-sultsshowthatratesofnitrificationanddenitrificationunderrealtimecontrolarerespectively1.40and1.86timesofthoseunderfixedtimecontrol,andthetimeofnitrificationanddenitrificationundertheabovecontrolmodeis60minutesand25minutesrespectivelyshorterthanthetraditionaloperatingmode.Therefore,useofORPandpHasrealtimecontrolparametersforshort-cutnitrificationanddenitrificationprocesscannotonlycontrolreasonablytheaerationandmixingtime,butalsoimprovenitrificationrateandshortenreactiontime,andthusreducingtheoperatingcost.
