| 摘要: |
| 以厌氧氨氧化菌(ANAMMOX菌)为基础开发的工艺被认为是最为简捷的生物脱氮过程.由于绝大多数废水中含有有机物,有必要研究有机物对ANAMMOX菌产生的影响.在ANAMMOX反应器内,大量有机物的引入会抑制ANAMMOX菌的活性,但是这种抑制作用往往是可逆的.此外在所有已被发现的5个ANA-MMOX菌属中,有4个属能不同程度地代谢小分子有机物(如甲酸、乙酸、丙酸等).综述了国内外在有机物对ANAMMOX菌及其工艺的影响研究领域所取得的成果,分析近5年对ANAMMOX菌代谢有机物的研究,从而为高氮低碳废水处理新途径提供新思路. |

| Abstract: |
| ANAMMOX bacteria is a kind of microorganisms that are related to the order Planctomycetales,able to autotrophically one-to-one combine ammonium and nitrite into dinitrogen gas.Based on ANAMMOX bacteria,ANAMMOX process is believed to be a shortcut pathway for biological nitrogen removal.Since most wastewater contains organic matter,it is of importance to understand the specific impact of organic matter on ANAMMOX bacteria.In an ANAMMOX reactor,large amount of organic matter could inhibit ANAMMOX activity,while such inhibitory is reversible.To date,among the five discovered ANAMMOX genera,four are demonstrated to be able to oxidize short chain organic matter,such as formate,acetate and propionate.This paper reviews the state-of-art of impact of organic matter on ANAMMOX bacteria,especially focuses on the catabolism of organic matter by ANAMMOX bacteria and the perspective application of such technology on the treatment of high nitrogen-carbon ratio wastewater. |
