以改进型UASB为反应器，采用连续试验方法，研究了不同浓度有机物对厌氧氨氧化反应的影响，并制定了通过调节亚硝态氮浓度解除厌氧氨氧化有机物抑制的方法。结果表明，当COD≤120 mg/L时，有机物对厌氧氨氧化反应产生促进作用，反之则产生抑制作用；NO2-能有效解除由于有机物引起的竞争性抑制，使厌氧氨氧化菌不受反硝化菌竞争性抑制影响的COD、NH4+-N、NO2--N投加质量比为1.6∶1∶1.92。

The effect of organic matter with different concentrations on Anammox reaction has been studied by using improved UASB reactor for continuous tests. A method for the disinhibition effect of organic matter on Anammox by regulating NO2--N concentration has been worked out. The results show that when COD≤120 mg/L,organic matter has promotive effect on Anammox,otherwise,it has inhibition effect. NO2-can effectively release the competitive in-hibition caused by organic matter. The dosage mass ratio of COD∶NH4+-N∶NO2--N,which makes the Anammox bac-teria not be affected by denitrifying bacteria competitive inhibition ,is 1.6∶1∶1.92.
