摘要
简述了厌氧氨氧化的研究进展,讨论了有机环境下同一反应器中厌氧氨氧化与反硝化的协同作用,推导了厌氧氨氧化的电子计量学方程式,以及有机环境下以葡萄糖为有机碳源时反硝化脱氮的电子计量方程式.电子计量学分析表明:由于反硝化将有机碳转变为CO2,可为厌氧氨氧化提供碳源,从而有利于厌氧氨氧化的进行;厌氧氨氧化产生的NO3-可被反硝化菌利用.由于厌氧氨氧化和反硝化反应过程均产生H+,会引起pH值升高,这一结果与所报道的试验结果相吻合.
The progress in the research on anaerobic ammonia oxidation （ANAMMOX） is briefly reviewed, and the combined reaction of ANAMMOX with denitrification in the condition of organic carbon source is discussed. The electronic stoichiometric equations of ANAMMOX and the denitrification with glucose as the organic carbon are then derived. The electronic stoichiometric analyses demonstrate that the ANAMMOX process benefits from the simultaneous denitrification because CO2 produced from organic carbon in the denitrification process can be used by ANAM MOX bacteria in the same bioreactor, and that the nitrate produced in the ANAMMOX process can be used by denitrification bacteria. However, H^＋ is produced in both ANAMMOX and denitrification processes. As a result, the pH value tends to increase with the development of bio-reaction, which accords well with the reported experimental results.
