新型沸石填料间歇硝化反应器的研究_安立超

新型沸石填料间歇硝化反应器的研究安立超　薛　涛　孙　静　高　瑾　周　进(南京理工大学环境科学与工程系,南京210094)摘　要　介绍一种新型沸石填料,用于提高生物脱氮系统中硝化反应器的硝化性能。试验结果表明,应用了沸石填料的硝化反应器的硝化性能得到了显著提高,在脱氮效率和速率上,与普通生物载体硝化反应器相比具有明显的优势。硝化反应器连续运行17d,出水氨氮基本在1mg/L以下,氨氮去除率在97%以上。该系统停止运行50d后再次启动,一周内硝化性能得以恢复。关键词　沸石　生物载体　硝化　脱氮StudyonthenovelintermittentnitrificationreactorusingpermutitfillingAnLichao　XueTao　SunJing　GaoJin　ZhouJin(DepartmentofEnvironmentalScienceandEngineering,NanjingUniversityofScienceandTechnology,Nanjing210094)Abstract　Anovelpermutitfillingforfurtherimprovingthenitrificationperformanceofthenitrificationreactorinbiologicalnitrogenremovalsystemispresentedinthispaper.Theexperimentalresultsindicatedthatthenitrificationreactorusingpermutitfillingcouldimprovenitrificationperformanceandhadevidentadvantagesoverthoseusingnor-malbiocarriersinefficiency.Duringthecontinuousrunningfor17d,NH3-Nintheeffluenthadbasicallybeenlowerthan1mg/LandtheremovalratioofNH3-Nhadalwaysbeenatalevelhigherthan97%.Thenitrificationperfor-manceofthereactorwasrecoveredinaweekafteri
