硝化

Microbiological nitrification and denitrification were considered to be the major sources of N2O in wastewater treatment processes.

微生物的硝化及反硝化过程为污水处理过程中N2O的主要产生源。

The technology of biological nitrogen removal by nitrosification denitrification, which has been developing a few years, is the combination between the oxidation of ammonia and the deoxidation of nitrite.

亚硝酸型硝化反硝化生物脱氮技术是近年来发展起来的新型的生物脱氮技术，其实质是氨的氧化与亚硝氮的还原相偶联。

In this paper,the research history and status were summarized.The processes of soil nitrogen input,interior transformation and output,including litter return,fertilization,atmosphere desposition,ammonification nitrogen fixation,ammonification,nitrification,denitrification,plant uptake,NH 3 volatilization and NO 3- leaching,were introduced.Finally,the tendency of study on soil nitrogen...

本文综述了森林土壤氮素转化与循环的研究历程和现状；介绍了凋落物的归还、施肥、大气沉降、自生固氮、氨化、硝化、反硝化、植物吸收、NH3 的挥发、NO3 -淋溶等土壤氮素输入、转化和输出的途径和过程；最后从研究目标、研究方法、研究对象和研究内容 4个方面归纳了森林土壤氮素转化与循环的发展趋势。

The inhibitory rate of DMHMP was lower than DCD when the same dosage added but higher than DCD while the added dosage of DMHMP was duplation of DCD.

当添加DMHMP的量与DCD相等时，其硝化抑制作用不如DCD，而当其添加量为DCD的2倍时，其硝化抑制效果明显优于DCD。
