Nitrous oxide formation and emission in selective non-catalytic reduction process

YANG Weijuan, ZHOU Junhu, ZHOU Zhijun, CEN Kefa

Frontiers in Energy 2007, Volume 1, Issue 2,   Pages 228-232 doi: 10.1007/s11708-007-0031-9

Abstract: Pulverized coal-fired boilers are not nitrous oxide sources because of high temperature combustion.The results show that NO emission decreases with increasing reaction temperature and NSR decreases whenAmmonia SNCR tests indicated that NO emission was 0 7 μmol/mol.About 8.7% of NO was transformed to NO, and NO emission was 27.8 μmol/mol at urea-SNCR test.Urea-SNCR is likely to bring NO emission problem.

Pilot-scale studies of domestic wastewater treatment by typical constructed wetlands and their greenhouse gas emissions

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 4,   Pages 477-482 doi: 10.1007/s11783-009-0155-8

Abstract: Three typical constructed wetlands (CWs) including Vertical Flow (VF), Free Water Surface (FWS), and Subsurface Flow (SF), and combined VF-SF-FWS constructed wetlands were investigated for the treatment of domestic wastewater with low C/N ratio. The performance of nutrient removal and the characteristics of greenhouse gas emissions, such as CH and NO, from these CWs were compared. The results indicated that the four types of CWs had high removal efficiencies for organic matter and suspended solid (SS). The combined wetland also showed a comparatively good performance for nitrogen and phosphorus removal, and the removal efficiencies for total nitrogen (TN) and total phosphorus (TP) were 81.3% and 84.5%, respectively. The combined CWs had a comparative lower global warming potential. The FWS CW had the highest tendency to emit CH and led to a higher global warming potential among the four types of CWs, which was about 586 mg CO/m·h.
