After inoculating little amount of aerobic active sludge to the anaerobic system, the rate of denitrification increased and the strength of nitrate accumulation decreased.

向纯厌氧颗粒污泥系统中投加少量的好氧活性污泥后，反硝化速度加快，亚硝酸盐累积强度减弱。

Now the study of MBR focuses on macro parameter control and system running effected by sludge characteristics, and there are little studies on molecule ecology of active sludge.

以前大部分研究集中于宏观工程参数控制和活性污泥特性对系统运行的作用过程，针对系统内活性污泥的分子生态学研究尚少。
