摘　　要：通过厌氧氨氧化批式实验,研究了在有机碳源环境下COD/NH4^＋ -N比、pH值以及NO2^- -N浓度对厌氧氨氧化反应的影响.结果表明：在有机碳源环境下,厌氧氨氧化作用和反硝化作用可以同时存在;适宜的COD/NH4^＋ -N比值范围在0-1.57之间;适宜的pH值范围应该在6.02-8.50之间,最适pH值为8.00;为了得到较好的脱碳和脱氮效果,在初始COD值为300mg/L时,初始NO2^- -N浓度不宜超过500mg/L,否则会抑制厌氧氨氧化反应和反硝化反应的进行.Batch experiments of the anaerobic ammonium oxidation process with organic carbon were performed at different ratios of COD to NH4^＋ -N content, pH values and NO2^- -N concentrations. The results show that （ 1 ） the anaerobic ammonium oxidation and the denitrification simultaneously exist simultaneously in the organic carbon condition; （2） the suitable ratio of COD to NH4^＋ -N content ranges from 0 to 1.57, and the suitable pH value ranges from 6. 02 to 8. 50 with a optimum value of 8.00; and （3） in order to obtain high carbon and nitrogen removals, the initial NO2^- -N concentrations should not be more than 500 mg/L when the initial COD value is 300 mg/L, otherwise, the anaerobic ammonium oxidation and the denitrification will be inhibited.
