第二次全国污染源普查安阳市环境空气 中NOx分析及治理对策研究

阐述了安阳市环境空气质量现状，分析了环境空气中二氧化氮浓度的变化趋势及与颗粒物、臭氧等大气污染物相关性，并对近10年大气降水类型进行了分析。结果显示，安阳市大气污染呈现燃煤污染与机动车污染共存的复合污染类型，大气降水经历了从硫酸型到硫酸—硝酸混合型的过渡过程，这一趋势表明，随着经济发展，氮氧化物排放对安阳市大气污染的影响愈发明显，并依据第二次全国污染源普查数据分析NO_x的排放源、排放区域、重点控制行业，提出治理NO_x的合理化建议。

Analysis on pollution characteristics of NOx and countermeasures in Anyang City based on second national pollution source survey

The status quo of environmental air quality in Anyang City was described，the trend of changes in the concentration of nitrogen dioxide in the ambient air and its correlation with atmospheric pollutants such as particulate matter and ozone were analyzed，and the types of atmospheric precipitation in the past 10 years were analyzed.The results showed that the air pollution in Anyang City presents a composite pollution type in which coal-burning pollution and motor vehicle pollution coexist.Atmospheric precipitation had undergone a transition process from sulfuric acid type to sulfuric acid-nitric acid mixed type.This trend showed that with economic development，nitrogen oxides the impact of emissions on air pollution in Anyang City had become more and more obvious.Based on the data of the second national pollution source survey，we analyzed the emission sources，emission areas，and key control industries of NO_x，and put forward reasonable suggestions for the treatment of NO_x.
