The N losses via denitrification and the N2/N2O emission ratio are highly uncertain, mainly due to methodological difficulties concerning measurement of N2 emissions. Here, we report on seasonal measurements of N2O and N2 emissions from the top soil of a winter wheat–summer maize double-cropping system in the North China Plain. A novel double cylin...
Biochar has been reported to reduce emission of nitrous oxide (N2O) from soils, but the mechanisms responsible remain fragmentary. For example, it is unclear how biochar effects on N2O emissions are mediated through biochar effects on soil gross N turnover rates. Hence, we conducted an incubation study with three contrasting agricultural soils from...
This study proposed two novel Combined Denitrification and Biofloc Technology (CDBFT) systems (one under blue LED light (L1) and the other without light (C1), each containing a denitrification (DE) reactor and a biofloc-based reactor) for the enhanced total nitrogen (TN) removal. Long-term operation (110 days) suggested that simultaneous nitrificat...
The strong greenhouse gas nitrous oxide (N2O) can be emitted from wastewater treatment systems as a byproduct of ammonium oxidation and as the last intermediate in the stepwise reduction of nitrate to N2 by denitrifying organisms. A potential strategy to reduce N2O emissions would be to enhance the activity of N2O reductase (NOS) in the denitrifyin...

One novel extraction process for denitrification of fuel based on ionic liquid was developed. Influence of water on this process was systematically investigated. The mechanism of this process was illustrated by density functional theory (DFT) calculations. The optimized extraction parameters were obtained by a series of experiments, such as mass ra...
