摘要: 通过反氧氨氧化批式实验,研究了在有机碳源环境下COD/NH4+ -N 比、pH 值以及NO2- -N 浓度对反氧氨氧化反应的影响.结果表明:在有机碳源环境下,反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 ,否则会抑制反氧氨氧化反应和反硝化反应的进行.

Abstract:

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 CO D 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.

Key words: anaerobic ammonium oxidation, denitrification, organic carbon resource, nitrogen removal
