A significant amount of nitrous oxide (N₂O ), which is one of the serious greenhouse gases, is emitted from nitrification and denitrification of wastewater. Batch wastewater nitrifications with enriched nitrifiers were carried out under oxygen-limited condition with synthetic (without organic carbon) and real wastewater (with organic carbon)in order to find out the effect of ammonium concentration on N₂O emission. Cumulated N₂O -N emission reached 3.0,5.7, 6.2, and 13.5 mg from 0.4 l of the synthetic wastewater with 50, 100, 200, and 500 mg/l NH₄+-N, respectively, and 1.0 mg from the real wastewater with 125 mg/l NH₄+-N.
The results indicate that N₂O emission increased with ammonium concentration and the load. The ammonium removal rate and nitrite concentration also increased N₂O emission. Comparative analysis of N₂Oemission from synthetic and real wastewaters revealed that wastewater nitrification under oxygen-limited condition emitted more N₂O than that of heterotrophic denitrification. Summarizing the results, it can be concluded that denitrification by autotrophic nitrifiers contributes significantly to the N₂O emission from wastewater nitrification.
