| Abstract: | In this study, a heterotrophic nitrification-aerobic denitrifying strain named GNR was isolated from swine wastewater. It was identified as a new strain of genus Acinetobacter through morphological and phylogenetic analysis. The optimal heterotrophic nitrification and aerobic denitrification conditions were investigated as the carbon source of trisodium citrate, C/N ratio of 10:1, initial pH of 8.0 and 6.0, respectively. The maximum removal efficiencies of ammonia and nitrate nitrogen with initial concentration of 50.0 mg/L both reached over 99.0% by strain GNR, after 30℃, 125 r/min shaking cultivation for 72 h. Under the optimal condition, the COD and ammonia removal efficiencies in diluted swine wastewater treatment reached 129, 73 mg/(L·g), respectively. The experimental results indicated that strain GNR had good application potential in wastewater denitrification. |
