摘要

近年来，厌氧氨氧化工艺（anaerobic ammonium oxidation

Anammox）作为一种新型的脱氮技术，由于其耗能少、效率高而被应用于高氨氮废水的处理中。然而，实际运行的厌氧氨氧化工程中有时会出现亚硝酸盐氧化菌（nitrite oxidizing bacteria

NOB）大量繁殖的情况，导致硝酸盐积累，脱氮效率下降。在一段式Anammox反应器中，通过控制某些影响因素，如调节体系中的溶解氧，控制游离氨和游离亚硝酸的浓度，调控碳源浓度以及外加中间产物（N2H4、NO和NH2OH）等方式，能够在维持Anammox工艺脱氮效率的同时有效抑制NOB。除了系统地综述一段式Anammox工艺中NOB抑制手段以外，将进一步讨论实际Anammox工程应用中抑制NOB大量繁殖行之有效的手段。

Abstract

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 treatment efficiency. Whereas

the accumulation of nitrite oxidizing bacteria (NOB) often occurs in full-scale Anammox process

leading to the accumulation of nitrate and deterioration of nitrogen removal effectiveness. In two-stage Anammox processes

NOB accumulation often occurs in partial nitritation stage

the inhibition of which has been discussed in details. While in one-stage Anammox process

NOB accumulation is more common and fatal due to the complexity brought by the coexistence of functional bacteria like ammonium oxidizing bacteria (AOB)

NOB

anaerobic ammonia oxidizing bacteria (AnAOB) and denitrifiers. It has been reported that NOB could be effectively suppressed in the one-stage Anammox process by some methods

e.g. regulating dissolved oxygen

altering the free ammonia and free nitrous acid concentration

adjusting carbon source and adding externally intermediate products (N2H4

NH2OH)

etc. The regulation methods mentioned above are systematically introduced on the basis of previous reports. Moreover

in practical Anammox crafts

the inhibitory methods should be conducted according to the specific operational conditions

and thus the available methods are further discussed.
