硝化反硝化过程中N2O释放影响因素
The influence factors on N2O emissions from nirification and denitrification reaction
摘要
Abstract
Based on the mechanism of N2O production, the influence factors were analysed including temperature, moisture content,NO2--N, substrate concentration, pH, alkalinity, O2 and substrate. The influencing law of N2O was explored to provide theoretical and technical support for N2O during biochemical process. N2O emission was the results that temperature, moisture content, NO2--N,substrate concentration and substrate acted together. Moisture content, C/N, substrate and temperature could affect dissolved oxygen concentration and N2O production in different ways. pH, NO2--N, NH3-N and temperature affected N2O release by inhibiting the activity of nitrate and denitrifying bacteria or the activity of enzymes of all the periods. Type of soil utilization, vegetation species and the parameters of wastewater denitrification could influence the nitrification and denitrification process and then affect N2O release.关键词
