Research progress on reaction mechanism and influencing factors of anaerobic ammonium oxidation coupled denitrification technology

为推动厌氧氨氧化(ANAMMOX)耦合反硝化技术在工业上的广泛应用,通过研究和文献分析,在对ANAMMOX耦合反硝化技术反应机理进行阐述的基础上,深入分析了温度、pH值、DO等环境因素以及有机物种类和浓度、碳氮比及基质比等底物因素对ANAMMOX耦合反硝化技术的影响。分析表明,厌氧氨氧化菌和反硝化菌的菌群所需环境条件相似,这为ANAMMOX与反硝化的耦合提供了环境基础。厌氧氨氧化菌和反硝化菌在底物因素上的差异,成为影响ANAMMOX耦合反硝化技术稳定运行的关键。今后需进一步探究底物因素对ANAMMOX耦合反硝化技术的影响。

In order to promote the wide application of anaerobic ammonia oxidation(ANAMMOX)coupled denitrificat-ion technology in industry,through research and literature analysis,on the basis of elaboration of the reaction mechanism of ANAMMOX coupled denitrification technology,the influences of environmental factors such as temperature,pH value and DO,as well as substrate factors such as type and concentration of organic matter,C/N ratio and substrate ratio on ANAMMOX coupled denitrification technology were deeply analyzed.The analysis shows that the environmental conditions required for anammox bacteria and denitrifying bacteria are similar,which provides an environmental basis for the coupling of ANAMMOX and denitrification.The difference of substrate factors between anammox bacteria and denitrifying bacteria is the key to the stable operation of ANAMMOX coupled denitrification technology.The influence of substrate factors on ANAMMOX coupled denitrification technology should be further explored in the future.
