Ammonia, nitrite and nitrate are the main contamination in the marine aquarium and aquaculture systems. Biological methods are used to be used in the removal process. 氨、亚硝酸盐和硝酸盐是水族箱和养殖系统中的主要污染物,通常采用生物法去除。
The experiment results indicate that the bacterium can metabolize ammonia, nitrite and nitrate when sufficient oxygen exists. 结果表明:该菌能在好氧条件下分别代谢氨氮、亚硝酸盐氮、硝酸盐氮,并通过好氧反硝化实现对总氮的去除。
The accumulation of ammonia, nitrite and nitrate, which are the main productions as the nutriment decomposes, does harm to the living fish and incurs the water enrichment. 有机物、营养物分解形成的产物能增大水体生物耗氧量,氨氮、亚硝酸盐、硝酸盐的积累可引起鱼类中毒死亡和水体富营养化。
In water, nitrogen exists in form of organic nitrogen, ammonia nitrogen, nitrite and nitrate. 在水中,氮是以有机氮、氨态氮、亚硝酸氮和硝酸氮的形式存在的。
The three bacteria have strong function of removing ammonia nitrogen, nitrite nitrogen and nitrate nitrogen. 三株菌分别对氨氮、亚硝酸盐氮和硝酸盐氮具有较强的脱除功能,且具有互生性。
