Abstract
The characteristic of NO_x emission from the incineration of organic wastewater containing aniline(C_6H_5NH_2) from lab was investigated at 800~950 ℃ in a bench scale bubbling fluidized bed.The results show that the conversion of organic N to NO_x is influenced by the temperature,the excess air and the content of organic nitrogen in wastewater.The conversion of N-NO_x decreases with increasing in temperature.When excess air coefficient is larger than 1.0～1.1,the conversion of N-NO_x increases with increasing in excess air coefficient,while when excess air is less than 1.0,the conversion of N-NO_x decreases rapidly to 5 percent at the excess air coefficient of 0.8.With the increase of aniline concentration in wastewater,the conversion of(N-NO_x) decreases,and is strongly dependent on temperature.
