The activities of nitrosification and anaerobic ammonium oxidation of both activated sludge and biofilm also were studied. Results showed that the nitrosification rate of activated sludge was 2.89 times than biofilm. AOB was the dominate bacteria in activated sludge.

单级自养脱氮系统中的活性污泥及生物膜样品均具有亚硝化活性，其中活性污泥最大比氨氧化速率为0.234mgN/mgVSS·d，生物膜为0.081mgN/mgVSS·d，活性污泥亚硝化活性是生物膜的2.89倍左右。

The sludge age in the reactor is large, so that nitrobacteria and nitrosomonas live together. The nitrogen removal via nitrite was possible mainly because the activity of nitrobacteria was inhibited rather than rushed out in number.

反应器内的污泥龄较长，硝酸菌和亚硝酸菌长期共存，发生短程硝化反硝化主要因为硝酸菌的活性受到抑制，而不是数量上受到淘汰。

By immobilization of denitrifying bacterium on different kinds of carbon fibers, effect of surface oxygenic functional groups of modified carbon fiber on denitrifying bacterium was investigated.
