If the wastewater concentration was too high, it would stimulate fungus, aminate bacteria, denitrifying bacteria and some anaerobic bacteria to propagate.

污水大，会刺激土壤中真菌、氨化细菌、反硝化细菌及些厌气菌的繁殖。

The most common method of biological nitrogen removal is by combining the nitrification of the autotrophic nitrobacter and nitrosomonas with the denitrification of heterotrophic denitrifying bacteria.

生物除氮最常利用的是将硝酸菌、亚硝酸菌之硝化作用与异脱硝菌之脱硝作用结合。
