亚硝态氮,是指土壤中以N(X形态存在的氮。亚硝态氮在土壤中含量很少,一般为1mg·kg以下,原因是在土壤中亚硝态氮转化为硝态氮的速率比铵态氮转化为亚硝态氮的速率快。植物可吸收低浓度的亚硝态氮,但若大量施用能使土壤溶液呈碱性。

亚硝酸盐态氮 nitrite nitrogen
The safe concentration was 0.838 mg/L. There was a negative correlation between concentrations of nitrite and the number of blood cells,while concentrations of nitrite and contents of hemoglobin(Hb) were not correlated.
亚硝态氮的浓度和血细胞数量呈负相关性,而与血红蛋白的含量不相关。

亚硝态氮与水体中各氮磷营养物间无相关关系。
Trite nitrogen and trite nitrogen in water is shows no correlativity.
在优化条件下,系统最终氨氮去除率能达到85%以上,亚硝态氮去除率达到95%以上,系统运行效果良好,且具有重现性。
Under optimum conditions, the removal efficiencies of ammonia and nitrite nitrogen could be above 85% and 95%, the system is running well and has reproducibility.
结果表明:利用曝气时间实时控制,在每个周期内氨氧化菌(AOB)降解氨氮质量大于亚硝酸盐氧化菌(NOB)降解亚硝态氮质量;AOB的净增数量大于NOB净增数目。
Analysis shows that more nitrogen is oxidized by ammonia oxidizing bacteria(AOB) than by nitrite oxidizing bacteria(NOB) with more growth of the AOB than the NOB in each cycle when using this method.
