一、氮氧化物污染源大气中的NOx污染物来源于两个方面,一个是自然源,另一个是人为源。人为排放的NOx绝大部分源于燃烧过程。现代火力发电厂是最大的固定源,机动车是主要移动源。随着我国经济的发展,NOx的排放量从1980年的468万 First, the nitrogen oxide pollution sources NOx pollutants in the atmosphere come from two aspects, one is a natural source, the other is a human source. Most anthropogenic emissions of NOx from the combustion process. Modern thermal power plant is the largest fixed source, the main source of motor vehicles. With the development of our economy, the emission of NOx has reached 4.68 million in 1980
