The dissolved oxygen had greater effects on heterotrophic bacteria,ammonifying bacteria and nitrifying bacteria.

溶解氧对异养细、氨化细、硝化细有大影响。

It also showed that more than one week was needed to activate Nitrosomonas by daily addition of 1.5 g NH4Cl and another 50 ml nitrifying bacteria to this system.

继续添加1.5克化铵和50毫升硝化细，要一星期活化亚硝酸。

Short rod bacteria and spirillum were dominant in the denitrifying reactor.While cocci were the dominant bacteria in the nitrifying reactor.

于脱硝槽中是以短杆和弯曲杆为优势，而于硝化槽中则是以球为主要的优势。
