反硝化的

Activated Sludge Model No.1 (ASM1) was used for bioreactor modeling. A case study was made for a complex activated sludge process including nitrification, denitrification and aeration. Optimization waas made for three reactor layouts.

采用ASM1模型来模拟生物反应，对包括硝化、反硝化和曝气等复杂过程的活性污泥废水处理系统进行了模拟和优化研究。

Terrestrial microorganisms play a vital role in soil nitrogen cycling. They participate in important ecological processes such as nitrogen fixation, ammonification, nitrification and denitrification.

土壤微生物在土壤氮循环中发挥着不可替代的作用，参与了包括固氮作用、氨化作用、硝化作用和反硝化作用等重要生态过程。

The experiment indicates that the nitrification and denitrification rates accelerate along with rising of the temperature.

试验表明，硝化和反硝化速率随温度的升高而加快。

The results of experiment imply that there is obvious simultaneous nitrification and denitrification process in the reactor.

实验研究表明，反应器内具有较明显的同步硝化反硝化过程。

A kind of bacteria with capability of heterotrophic nitrification-aerobic denitrification have been reported in recent years.

近年来发现了一类具有偶联异养硝化-好氧反硝化功能的细菌。

Put forward current and synchronous nitration finally to turn over nitrify to still treat the problem of thrash out.

最终提出了目前同步硝化反硝化尚待探究解决的新问题。

NH3-N is convered in to nitrogen under the condition of anoxic, which is termed as nitrification.

生物脱氮是指利用微生物将含氮化合物中的氮转化为氮气，它分为硝化和反硝化两个过程。

Because lengthen the 2nd anoxic - good oxygen paragraph mud age comes 15 ～ 20h, be helpful for nitrify / the growth that turns over nitrify bacterium, rose to take off nitrogen to handle the effect thereby.

由于延长第二缺氧-好氧段污泥龄至15～20h，有利于硝化/反硝化菌的生长，从而提高了脱氮处理效果。

Then made them into immobilized cells respectively using polyvinyl alcohol and sodium alginate as carrier.The experiments werecarried out for the selection of nitrosification and denitrification conditions.

然后用聚乙烯醇和海藻酸钠作为载体将它们分别制成固定化细胞，单独作硝化和反硝化试验的条件选择。

The concentrations of NH+4-N,pH and NO-3-N first increased,but later they decreased smoothly. During the biodegradation process, AM was first hydrolyzed,then nitrified and denitrified,and the final products were oxidized into N2,CO2 and H2O.

不同时间段体系内NH+4-N、pH和NO-3-N都随着降解时间的增加逐步上升，但是达到一定时间后会下降，表明AM在降解过程中先水解，然后发生硝化反应，进而发生反硝化反应，最终AM降解成N2、CO2和H2O。
