查询词典 Nitrobacter

Exploratory study was made on the Guanting reservoir influent treatment by using two-stage BAF at extreme low temperature.The results show that the removal of organics and ammonia nitrogen is seriously inhibited due to low temperature,and the conversion of nitrite into nitrate is no longer a limiting factor of complete nitrification.One possible hypothesis is that the activity of nitrobacter is hi gher than that of nitrosomonas at extreme low temperature.

摘 要：两级曝气生物滤池在极低温度下(1℃以下)处理官厅水库入库水的探索性研究试验结果表明，有机物和氨氮的去除受到了低温的严重抑制，亚硝酸盐转化成硝酸盐不再是完全硝化反应的限制步骤，这可能是在极低温度条件下硝酸菌的活性高于亚硝酸菌活性的缘故。

The final enrichment culture is streaked on Nitrobacter agar medium and tiny colonies appearing after 14 days are indicative of Nitrobacter.

最后浓缩文化是飞速Nitrobacter培养基和小殖民地后14天内出现的Nitrobacter具有象征意义。

The number of heterotrophic bacteria and nitrifying bacteria increased with the time of the hydraulic retention time, contrary to the nitrobacter.

根际细菌和硝化细菌数量随着水力停留时间增加而增加，而根际反硝化细菌数量则减少。

The rooting effect is more obvious on nitrosomonas than on nitrobacter.

根际细菌、真菌和放线菌的数量均比非根际多，R／S平均值分别为70.3、9.5、2.9。

The research results showed that the growth of Nitrobacter always depended on the conversion of ammonia-nitrogen to nitrite-nitrogen by Nitrosomonas under both no aeration and aeration.

研究结果表明，在无曝气条件下和曝气条件下，填料上硝酸盐细菌的生长均依赖于亚硝酸盐细菌转化氨氮为亚硝酸盐氮的过程。

Experiments discovered that over 10.5g/L influent salinity can inhibit the growth of nitrobacter, then results in the accumulation of nitrite and the short-circuit denitrification.

污水中的足够盐度能够造成硝化过程中亚硝酸盐的积累，形成短程硝化过程，这一发现对含海水城市污水的生物脱氮处理具有重要的理论意义与实用价值。

Stable nitritation is realized because the nitrobacter is sensitive to the changing environment. When the dissolved oxygen and pH values in SBRⅠ and SBRⅡ are 2. 4-3. 0mg/L, 7. 0-8. 5, 1. 5-2. 0mg/L and 7. 0-8. 5 respectively, a lot of nitrate isn't found during operation in two months, and nitrosation rate is over 80% in two aerobic reactors.

将SBRⅠ、SBRⅡ好氧反应器的溶解氧、pH分别控制在7.0-8.5、2.4-3.0mg／L及7.0-8.5、1.5-2.0mg／L时，依赖SBR反应器水质波动大、硝酸菌对环境变化敏感的特点，在较高浓度NH〓-N条件下，实现了稳定的亚硝化反应，系统运行近两个月，没有大量硝酸盐的积累，两个好氧反应器的亚硝化率均在80％以上。

Nitrosomonas is successfully cultured in two aerobic reactors in this paper. Experimental results show that two-stage SBR is superior to one-stage SBR at the same hydraulic residence time. Stable nitritation is realized because the nitrobacter is sensitive to the changing environment.

在两个SBR好氧反应器中成功培养出大量的亚硝酸菌，研究结果表明：在水力停留时间相同时，两级SBR好氧反应器的脱氮效率优于一级SBR好氧反应器。

Benieficial bacteria like Nitrosomonas and Nitrobacter colonize the pore walls to promote ideal conditions for the biologican removal of ammonia and nitrite.

有益的细菌像亚硝化毛杆菌与硝化杆菌依附在孔壁上以加速对于氨与硝酸盐清除的理想环境。

The results showed that the percentage of ammonia oxidizing bacteria and nitrite oxidizing bacteria in the activated sludge was 15.7%±3.7% and 12.9%±3.2%, Nitrosomonas europaea-Nitrosococcus mobilis lineage were the dominant AOB, Nitrobacter spp.

结果表明，污泥中氨氧化菌的含量为15.7%±3.7%，优势菌属为Nitrosomonas europaea-Nitrosococcus mobilis；亚硝酸氧化菌的含量为12.9%±3.2%，优势菌属为Nitrobacter spp。。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
