1) nitrite accumulation
亚硝酸盐氮积累
2) accumulation rate of nitrite nitrogen
亚硝酸盐氮积累率
3) nitrite accumulation
亚硝酸氮积累
1.
It could be obtained a high and stable nitrite accumulation with on-line process control at low DO concentration.
结果表明,A/O工艺硝化过程中DO和pH在好氧区的变化可分为3种典型情况,并获得pH曲线可以作为短程硝化反应的控制参数,基于在线过程控制,可以获得稳定较高的NO2--N积累,而不采用在线过程控制,NO2--N积累很不稳定;当亚硝化过程完成继续曝气将造成亚硝酸氮继续氧化为硝酸氮,从而亚硝酸氮积累率降低。
2.
It was realized nitrite accumulation in a pilot-scale pre-denitrification process at normal temperature.
通过试验实现了前置反硝化工艺亚硝酸氮的积累,从温度、pH值、游离氨(FA)浓度、污泥龄、溶解氧(DO)浓度等几个影响亚硝酸氮积累的主要因素逐一分析。
4) accumulation of nitrite
亚硝酸盐积累
1.
Incubation experimental results indi-cated that the accumulation of nitrite under low temperature,especially freezing-thawingconditions,is due to enhancing involvement of organic matter in mineralization by freezing-thawing events,which provided the available organic carbon compounds for denitrifyingbacteria,The results have been used to interpret Keshan disease enviro.
利用不同类型土壤－水系统，加入一定量的ＫＮＯ＿３溶液，进行温度和冻融对脱氮化作用的影响以及亚硝酸盐积累规律的研究，培育实验结果表明，低温下，尤其是冻融条件下亚硝酸盐积累，是由于冻融加强有机质的分解及矿化作用所引起。

A mathematic model for nitrite accumulation in a hydrogenotrophic denitrification system running in a sequencing batch mode was developed and denitrification coefficient α was defined to describe the process of nitrite accumulation.
建立了序批式反应器氢自养反硝化系统中亚硝酸盐累积的数学模型,定义了反硝化系数α来描述亚硝酸盐的累积状况,研究了序批式反应器内加入亚硝酸盐前后硝酸盐和亚硝酸盐还原速率以及亚硝酸盐累积浓度的变化情况。
补充资料：亚硝酸盐氮
分子式：
CAS号：
性质：又称亚硝态氮或亚硝酸盐氮。指亚硝酸盐中所含的氮元素。水和土壤中的有机物分解而生成铵盐，在有氧的条件下，会转化成亚硝酸盐和硝酸盐；亚硝酸氮是总氮(或全态氮)中的组成部分之一。
