- 摘要：对序批式生物膜法工艺中所表现出来的脱氮特性进行了探讨, 并提出了过量储存SND脱氮作用机理.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.
- Abstract：The nitrogen removal characteristics in sequencing batch reactor of submerged biofilm process were studed and the mechanism of over storage—nitrogen removal with SND was set up.The results in dicated that nitrogen removal in the anaerobic phrase depended largely on the over storage function of the biofilm to the carbonaceous and nitrogenous organism, and nitrogen removal in the aerobic phrase depended on the SND function of biofilm. The organic carbon over storaged in the anaerobic phrase in the biofilm provided the major of organic carbon in the process of denitrification.
- Key words：sequencing batch reactor biological nitrogen removal simultaneous nitrification and denitrification(SND) over storage
