硝化作用

The effects of all react areas and their features were also discovered. In anaerobic cells the organic matters acidify and hydrolyze, phosphate are released, nitrate will be denitrified if it exits.

揭示了MSBR各反应区自身特点及在整个流程中作用：厌氧池承担有机物的酸化水解、厌氧释磷和部分反硝化的功能。

Six kind of bacteria were isolated from the mixture, and it was approved is that when the temperature was 30~35 oC ,pH was 8.0,DO＜1.2mg/L,the condition was adapted to Nitrosomas and the rate of remove about ammoniate was more than 80%.

得出在温度为30-35oC， pH值为8.0，DO＜1.2mg/L的条件下，最适合混培物的生长，氨氮的去除率可达80%以上，从而有效地降低抑制作用，使得后续反硝化能够顺利进行。

Based on the previous studies and combined with the national important scientific special item—the projection of water environment improvement and comprehensive demonstration in Suzhou city. The influence to water quality melioration under different conditions of packing types, stuffing rate, air supply and hydraulic loading using water of Miaojia river as experiment water sample; the water contaminate removal ability by the absorption and interception of charcoal filling and the research of the denitrification rate of charcoal filling were discussed in the paper. Furthermore, the activity of the biofilm on savageness and artificialness filling surface in the projection demonstration riverway were also analyses.

本人在总结前人研究的基础上，结合国家重大科技专项——苏州城市水环境质量改善与综合示范项目，研究了不同填料基质、填充率、曝气量、水力负荷条件下生物填料对苏州城市重污染河道水质的改善效果；木炭填料吸附、截留作用对水体污染物去除能力及其反硝化脱氮能力；分析了项目示范区河道内天然填料及人工填料挂膜成熟的生物膜活性。

When the synergism was in a good state, characteristic changes were presented in the pH value and alkalinity.

在厌氧氨氧化与反硝化协同作用良好时， pH值和碱度均存在特征性变化。

Soil net N nitrification would increase with the increase of the %FNDA of Lespedeza bicolor. Lespedeza bicolor could fix a large amount of N〓, but was also likely to increase the N leaching loss.

胡枝子固氮作用越强，土壤有机氮的净硝化量就越大，胡枝子在从大气中获取大量〓的同时，很可能会增加氮素的淋溶损失量。

Following this lead, they decided to investigate the role of nitration in one disease, Parkinson's, in more detail.

随着研究的深入，她们决定研究硝化反应在帕金森症中的作用。

Role of protein tyrosine nitration in neurodegenerative diseases and atherosclerosis.

神经退行性疾病和动脉粥样硬化中蛋白质酪氨酸硝化的作用

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

Installed in surface aeration oxidation ditch with prepositive denitrification treatment, using the role of the mixture Gravity, it can achieve any reflux ratio requirements of process design by adjusting the cross-section area of water.

安装在设置有前置反硝化区的表曝型氧化沟内，利用混合液重力流的作用，通过调节过水断面面积，实现工艺设计的任意回流比要求。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
