| 摘 要： | N2O是大气中重要的温室气体之一,控制其大气浓度的增长具有重要意义.研究表明,污水生物处理的硝化反硝化过程是N2O的重要源强之一,N2O的逸出主要发生在亚硝化过程和反硝化过程,而且逸出量受环境因素影响很大.深入了解N2O的逸出机理和外界因素的影响规律是有效控制N2()的前提和基础. |

| Abstract: | N2O is an important green house gas in the atmosphere, so it is very important to control the increase of N2O concentration. Research has suggested that biological nitrification and denitrification of wastewater is one of important source of N2O, and its emission occurres during nitrosofication and denitrification. Moreover, the amount of N2O emission is dramatically influenced by many environmental factors. Fully understanding of emission mechanics and affecting rules of various factors is a premise to control N2O. |
| Keywords: | Nitrification and denitrification N2O Mechanism Biological denitrification Wastewater treatment |
