氮氧化物气体的产生及其对厌氧氨氧化的影响研究

硝化、反硝化生物脱氮反应,因产生N2O温室气体,开始引发一些环保工作者的关注。新开发的厌氧氨氧化工艺在生物脱氮方面具有无可比拟的优越性。在其脱氮的3种反应途径中,也可能产生NO、NO2和N2O微量气体。文章对目前厌氧氨氧化反应中,这3种微量气体的产生情况进行了综述,并总结了这3种气体对厌氧氨氧化反应的影响。提出考察厌氧氨氧化过程中温室气体的排放情况和如何减少或控制温室气体的排放将成为厌氧氨氧化工艺应用中重要的研究方向之一。

Generation of Nitric Oxides and the Influence on Anaerobic Ammonium Oxidation

Many environmentalists start to ponder about nitrification and denitrification reactions during which N2O as a greenhouse gas is produced.The newly developed anaerobic ammonium oxidation process has its incomparable superiority in biological nitrogen removal.In the three reaction pathways of nitrogen removal,trace gases such as NO,NO2 and N2O can also be generated.The production of those three trace gases on the current anaerobic ammonia oxidation process are reviewed,as well as the summary of influence caused by the three gases.The investigation of greenhouse gas emissions and how to reduce or control greenhouse gas emissions will be one of the important research fields in the application of anaerobic ammonium oxidation process.
