查询词典 nitrobacteria

On the silicate plate, pure nitrobacteria were obtained.

在硅酸胶平板上分离到硝化细菌的纯培养物。

The results showed that short SRT bacteria and nitrobacteria can be cultivated separately in the reactor so that the concentration of nitrate in the circumfluence sludge is low, which is lower than 1 mg/L.

结果表明，在反应器内能实现短泥龄细菌和硝化细菌的分相培养，有效降低了回流污泥中硝态氮的质量浓度，其值小于1mgL^(-1)。

But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.

1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。

To oxidizeinto nitric acid,nitrous acid,or any nitrate or nitrite,especially by the action of nitrobacteria.

硝化将氧化成硝酸、亚硝酸或任何硝酸或亚硝酸酯，尤指通过硝化细菌的作用

To oxidize into nitric acid, nitrous acid, or any nitrate or nitrite, especially by the action of nitrobacteria.

硝化将氧化成硝酸、亚硝酸或任何硝酸或亚硝酸酯，尤指通过硝化细菌的作用

Therefore,we tested the decomposition and mineralization of organic matter within 24 hours in an aquarium to investigate the role of nitrobacteria in the process.

有机质矿化分解的氮、磷等营养元素极易引起水体富营养化，进而影响生命体在水中的消长，水体有机质矿化是目前研究的热点[1-3]。

The way of high frequency intermittent aeration suppresses the activity of nitrobacteria, and also...

实验结果表明，高频间歇式曝气方式在抑制了硝酸细菌的活性的同时也消除了亚硝酸盐浓度和pH大幅波动对亚硝酸细菌和厌氧氨氧化细菌活性的影响；在曝气阶段，溶解氧浓度被控制在1.2～1.4mg·L-1，亚硝酸细菌成为主体细菌，亚硝酸盐积累；在缺氧阶段，随着溶解氧浓度迅速降低，厌氧氨氧化细菌成为优势菌种，曝气阶段积累的亚硝酸盐与氨氮同时被去除。

The results indicate that excellent nitration of NH,-N need the sufficient removal of COD to prevent the restrain of toxicant on the nitrobacteria.

指出NH_3-N完全硝化的前提是废水中COD的充分降解，以消除有毒物质对硝化菌的抑制作用。

Usually rod-shaped bacteria that oxidize ammonia or nitrites: nitrobacteria.

通常为杆状细菌科可以氧化氨或亚硝酸盐；硝化细菌。

So we conjecture that the actionof heterotrophic nitrobacteria occurres in the A/O process.

进水COD浓度为600mg／L时，二者TN去除率分别为95％和84％。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
