Heterotrophic nitrification characteristics of five aerobic denitrifiers which belong to different genus were studied.
对五株不同菌属的好氧反硝化菌进行了异养硝化性能研究。

The quantity of nitrifiers disposed by organic manure was a little fewer than that by urea treatment, but there were obviously more denitrifiers.
施用有机肥（酵素菌肥）处理的硝化细菌数量低于施用尿素处理，但反硝化细菌数量则明显高于尿素处理。

The step-fed sequencing batch reactor (SFSBR) is a new type of the enhanced nitrogen removal system, characterized by a multiple anoxic feeding for supplying the organic carbon source to denitrifiers.
