  nitrification denitrification
Interaction between the relative increase in available N for N2O production by shading and the presence of root exudates promoted N transformation (nitrification/denitrification) and N2O emission.
      
On a temporal and a spatial scale, nitrate patterns in such systems reflect the close connection to subsurface flow and nitrification/denitrification processes in the soil.
      
This relationship suggests that approximately 13% of the N incorporated into phytoplankton in shelf waters is eventually denitrified in the sediments via coupled nitrification/denitrification, assuming a C:N ratio of 6.625:1 for phytoplankton.
      
A model of coupled nitrification/denitrification was developed for continental shelf sediments to estimate the spatial distribution of denitrification throughout shelf regions in the North Atlantic basin.
      
The relatively low fluxes under anaerobic conditions and the low rate of N03-/N02- removal from the overlying water indicates coupled nitrification/denitrification produced the observed N2 fluxes.

In this work, a treatment technology of PACT decarbonization nitrification-denitrification was studied for the coke plant wastewater, by which satisfactory removal of COD, ammonia nitrogen, nitrate and nitrite was achieved. This treatment scheme claims high flexibility, easy operation, and low investment, and particularly suits rectification to existing installations for treatment enhancement to meet increasingly demanding discharge standards.

采用PACT—硝化—-反硝化工艺,处理焦化废水。结果表明,排放水的COD可降至100 mg/l、NH_3-N浓度可达15mg/l,基本达到排放标准。该工艺适合于现有焦化厂废水处理设备的改造。

A shorttened nitrification-denitrification system has been found to have the advantages such as high removal of loading, low COD and NH3-N concentrations in effluent and less requirement for carbon in denitrification. When the influent COD, NH3-N and TN concentrations are 1204.8, 274.3 and 443mg/L, respectively (HRT=26.2h), the effluent COD, NH2-N, NO3-N and TN are 36.3, 12.1, 9.25, 2.46 and 44.4mg/L, respectively. It was also showed in this paper that the system used in this study indeed followed...
