摘要
一氧化二氮是(N_2O)一种化学性质稳定的温室气体,其全球变暖潜能值(GWP)约为CO_2的300倍。大气中N_2O主要来自农业排放、工业和化石燃料燃烧、生物质燃烧、废水及城市垃圾等。依据对特定地区的数据采集,并结合DNDC模型能较好地估算整个地区N_2O的排放量。氨及氨盐在微生物作用下发生的硝化与反硝化反应是生成N_2O的主要反应。通过采用优化生产工艺、催化反应、添加抑制剂等措施可有效控制N_2O的排放。
Nitrous oxide（N_2O） is a chemically stable greenhouse gas with a global warming potential（GWP） of about300 times that of CO_2. The main sources of N_2 O in the atmosphere are agricultural emissions, industrial and fossil fuel combustion, biomass combustion, waste water and municipal waste. Based on the data collected in specific areas, combined with DNDC model, N_2 O emissions throughout the region can be well estimated. The nitrification and denitrification reactions of ammonia and ammonium salts under the action of microorganisms are the main N_2 O reactions. Through the use of optimization of production processes, catalytic reaction, adding inhibitors and other measures can effectively control the N_2 O emissions.
