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
