Establishment Of Emission Inventory Of Air Pollutant Sources In Fushun

According to the serious heavy industry city and Fushun city air pollution,this article collection of Fushun city artificial source and natural source activity level which from three aspects of point source,linear source and non-point source,combined with GIS and emission factor method to establish a listing pollutants emission of Fushun city,analysis of Fushun city air quality situation and pollution source of the main atmospheric pollutants emission characteristics and share rate and the key source of industrial source and mobile source emissions reduction potential analysis.Listing contains major pollutants SO₂,NO_X,PM₁₀ and PM_2.5,etc.The annual discharge of SO₂,NO_X and PM is estimated:50145 t,53532 t,128857 t.Fushun is a city with high pollutant emission intensity in Liaoning province.The main emission sources of SO₂ are industrial fuel combustion and civil loose coal combustion;The main emission sources of NO_X are industrial sources and mobile sources;The main emission sources of particulate matter are dust source and industrial source.Mobile source and biomass source have a greater share of CO.Based on the main pollution sources of pollutant emission characteristics,thermal power and heating industry is a major source of contributions,SO₂,NO_X and smoke dust emission source?powder?mainly concentrated in urban areas,accounts for more than 90%to the total emissions;In the three kinds of dust,there is a large proportion of particles in the dust,and the overall spatial emission characteristics of the dust source are decreasing from the urban to the edge.Mobile source RGL block ownership proportion is big,is still small,new energy vehicles of different vehicles emissions differences,including gasoline vehicles of CO,CH emissions is larger and the share rate of diesel for NO_X,PM₁₀ and PM_2.5 emissions contribute significantly;On the basis of the atmospheric pollutants emission characteristics at the same time,in view of the Fushun city the key source of industrial and mobile base build different emission scenarios,under more pollutants emission reduction potential analysis,provide important basis for air pollution control and early warning of Fushun city.
