摘　　要：对淹没式生物膜工艺中所表现出来的脱氮特性进行了探讨 .厌氧段脱氮主要靠生物膜对含碳氮有机物的过量储存作用 ;好氧段脱氮主要靠生物膜的SND作用 .反硝化的有机碳源主要为生物膜中在厌氧段过量储存的有机碳源 ;并提出了过量储存 SND脱氮作用机理 .确定出优势菌属为假单胞菌属 ,其依次顺序为气单胞菌属、芽孢杆菌属、微球菌属。The article discusses the nitrogen removal characteristics in sequencing batch reactor of submerged biofilm process.Nitrogen removal in the anaerobic phase depended largely on the over storage function of the biofilm to the carbonaceous and nitrogenous organism,and nitrogen removal in the aerobic phase depended on the simultaneous nitrification and denitrification(SND)function of biofilm.The organic carbon over storaged in the anaerobic phrase in the biofilm provided the major of organic carbon in the proce...
