Abstract: Anaerobic ammonium oxidation (Anammox)，a new biological nitrogen removal process in wastewater treatment，is very suitable for the treatment of wastewater containing organic matters. This paper introduces the characteristics of anaerobic ammonium oxidation process，especially the inhibitive and stimulative mechanisms of organic matters to the bacteria. Two mechanisms are attributed to organic matters induced inhibition，one is heterotrophic denitrifying bacteria promoted by organic matters can compete with anammox bacteria for substrates；the other one is that alcohols，antibiotics and other toxic organics in wastewater leads to toxic inhibition to anaerobic ammonium oxidation bacteria. The stimulation of organic matters to anaerobic ammonium oxidation bacteria also can be explained in two aspects：one is that certain organic matters can be used by anaerobic ammonium oxidation bacteria as energy source，and thus enhance their metabolism；the other is anaerobic ammonium oxidation bacteria and denitrifying bacteria can form symbiote with proper C：N ratio. The pretreatment of toxic organic wastewater，acclimation of anaerobic ammonium oxidation sludge，sequential biocatalyst addition are feasible solutions to the problem.
