反硝化的

The materiel balance of Nitrogen and Phosphorus in the static examination shows: In eliminating of the nitrogen, Ipomea aquatica absorbing and the artificial medium nitrify contributing up to 31.8% and 38.7%; in eliminating the phosphorus, the contribution that Ipomea aquatica absorbing is 26.7%.

静态运行条件下的氮磷物料衡算显示：在总氮的去除中，空心菜吸收及人工介质反硝化的贡献分别达到了31.8%、38.7%；在总磷的去除中，空心菜吸收的贡献为26.7%。

Effects of temperature,pH value, electron donor and electron acceptor on denitrification were studied.

研究了温度、pH值、电子供体种类及电子受体种类对反硝化的影响。

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。

The experimental result of anaerobic ammoniation shows, the most appropriate hydraulic retention time is between six and eight hours, the longer the HRT , the higher the rate of NH3-N net increase.

现场调查分析表明，屠宰废水是一类富含有机氮的有机废水，其NH_3-N浓度在整个生物处理工艺过程中存在一定变化规律，特别在厌氧之后，NH3-N浓度将大幅增加(净增加70%—150%)，显然多数以进口NH_3-N指标进行硝化及反硝化的设计是错误的，且是导致NH_3-N难以达标的一个重要原因。

At the end of this paper, the factors which influence the shortcut denitrification was discussed.

本文最后还对影响短程反硝化的因素作了讨论。

The biochemical reaction mechanism and kinetics of denitrification are the theoretical foundation of biological nitrogen removal.

反硝化的生化机理及动力学是生物脱氮技术的理论基础。

Test result makes clear electrode - biomembrane reactor is OK the approach that saltpetre can oppose nitrify through be being raised oneself purify of nitrogen of nitric acid salt , but the purify efficiency of nitrogen of nitric acid salt and total nitrogen .

试验结果表明电极-生物膜反应器可以硝可以通过自养反硝化的途径将硝酸盐氮去除，但硝酸盐氮和总氮的去除效率。

The invention discloses a disposing method of ammonia nitrogen waste water in the effluent disposal technological domain, which is characterized by the following: sieving heterotrophic nitrobacteria and aerobic denitrobacteria with stronger environment adaptive ability to nitrate and denitrate simultaneously; constructing mud nitrated and denitrated system to dispose waste water with nitrogen simultaneously to satisfy different DO densities.

为了解决同步硝化反硝化过程中菌种来源不明，调控困难，硝化和反硝化对DO浓度要求不同，在实际工程中难以实现同步硝化反硝化，本发明筛选出对环境有较强适应能力的异养硝化细菌和好氧反硝化细菌，采用异养硝化细菌和好氧反硝化细菌构建同步硝化反硝化污泥体系处理含氮废水，具有投资少，费用低，处理效果好，不仅去除废水中的氨氮，而且对总氮也有较高的去除率。

The mutative rule of pH is also studied in the reaction and the regular pattern is found.

短程硝化反硝化的标志是有稳定且高效的亚硝酸盐的积累。

Nitrites and ammonia cannot be used by plants as a nitrogen source.

因为反硝化的产物不能被植物当作氮源来使用。
