摘要：无机碳源达到一定浓度时，对厌氧氨氧化菌有抑制作用，在ASBR反应器中进行的无机碳源对厌氧氨氧化菌研究发现，当投加量大于2g/L时，厌氧氨氧化菌代谢受到严重抑制，但是这种抑制是可逆的。当无机碳源恢复到1g/L时，厌氧氨氧化菌的代谢恢复正常。根据该情况在UASB反应器中对该问题进行深入研究。

Abstract: When the inorganic carbon source reaches a certain concentration, the anaerobic ammonium oxidizing bacteria have. The study of inorganic carbon source in ASBR reactor was found in the study of anaerobic ammonium oxidizing bacteria, when the dosage was more than 2g/L, the metabolism of anaerobic ammonium oxidizing bacteria was severely inhibited. But this inhibition is reversible. When the inorganic carbon source was restored to 1g/L, the metabolism of anaerobic ammonium oxidizing bacteria returned to normal. According to this situation, the problem is studied deeply in the UASB reactor.

Key words: anaerobic ammonium oxidation; Inorganic carbon source;substrate inhibition.
