A review on regulation methods of nitrite oxidizing bacteria in one-stage anaerobic ammonia oxidation process

摘要: In recent years,anaerobic ammonium oxidation (Anammox), a new technology for nitrogen removal, has been used in the treatment of high-strength ammonia wastewater due to its low energy consumption and high efficiency. Whereas, accumulation nitrite oxidizing bacteria (NOB) often occurs full-scale Anammox process, leading nitrate deterioration removal effectiveness. two-stage processes, NOB partial nitritation stage, inhibition which discussed details. While one-stage is more common fatal complexity brought by coexistence functional like (AOB), NOB, anaerobic (AnAOB) denitrifiers. It reported that could be effectively suppressed process some methods, e.g. regulating dissolved oxygen, altering free nitrous acid concentration, adjusting carbon source adding externally intermediate products (N2H4, NO, NH2OH), etc. The regulation methods mentioned above are systematically introduced on basis previous reports. Moreover, practical crafts, inhibitory should conducted according specific operational conditions, thus available further discussed.
