摘要
在无分子氧环境中,同时存在NH4+和NO2-时,NH4+作为反硝化的无机电子供体,NO2-作为电子受体,生成氮气,这一过程称为厌氧氨氧化。目前已经发现了3种厌氧氨氧化菌(Brocadia anamm oxidans,Kuenenia stuttgartiensis,Scalindua sorokinii);对厌氧氨氧化菌的细胞色素、营养物质、抑制物、结构特征和生化反应机理的研究表明,厌氧氨氧化菌具有多种代谢能力。基于部分硝化至亚硝酸盐,然后与氨一起厌氧氨氧化,以及厌氧氨氧化菌与好氧氨氧化菌或甲烷菌的协同耦合作用,提出了几种生物脱氮的新工艺(ANAM-MOX、SHARON-ANAMMOX、CANON和甲烷化与厌氧氨氧化耦合工艺)。
Anaerobic ammonium oxidation is a new process in which ammonium is oxidized with nitrite as the electron acceptor under anoxic conditions, producing dinitrogen gas. Three anammox bacteria （ Brocadia anammoxidans, Kuenenia stuttgartiensis , Scalindua sorokinii） have been found recently. The investigation on cytochrome spectra, nutrition , inhibitors, cell structures and biochemistry reaction mechanisms in anammox bacteria indicated that anammox bacteria had the potential of diverse metabolic types. Several novel microbial nitrogen removal processes have been developed （ ANAMMOX process, SHARON-ANAMMOX process, CANON process and integration of methanogenesis with anaerobic ammonium oxidation） .
