EDMS Application And Study Of Air Pollution Forecast In The Airpor

The sustainable economic growth in the world, economic globalization and regional economic integration continuously strengthen, national airspace constantly open to the global airport industry development provides a strong support and broad space for development. In this situation, increasing number of airports around the world, each airport aviation business increasing, to 2020, the civil airport layout planning in our country a total of 244, 97 from 20076, the new airport.Air transport because of its high efficiency, high speed, the advantages of space constraints, is becoming more and more get the favour of people, however, aircraft and cruise, the exhaust emission of atmospheric pollutants is also growing, the domestic famous gray haze expert,Unprecedented attention caused by air pollution, the competent department of environmental protection and permanent residents pay more and more attention to the perimeter of the airport aircraft exhaust pollutant’s impact on the environment.In the aircraft exhaust,there is mostly CO2、H2O、NOX、S02、CO、VOCs and orther gas.Previous eia projects, For the twin engine airplanes travel 800 km, 25% of the emissions from land and take off, Aircraft engine emission pollution due to its locality and concentration characteristics of the environmental impacts of the ground in a large and near the airport on the ground, can cause local exhaust pollutant concentration is quite high : according to the American EPA figures released in the United States, the aircraft engine of NOx and CO is accounted for 2% of total flow sources produce NOx and CO, but in some airport area, the proportion rose to 4%, among them, the commercial aircraft engine emissions, the fastest growth in Los Angeles. Therefore, with the rapid development of aviation industry, especially in the commercial aviation industry, the potential impact on the health and the environment pollution, make the international community pay more and more attention to the environmental impact of regional aircraft engine and around the airport staff health problems. From the Angle of the environmental and health double, composition of aircraft engine emissions, emissions, diffusion concentration of airport environmental impact study, appears especially important.At home and abroad,there have on listing of typical airport air pollution emissions and emissions characteristics research of literature, analysis of aircraft landing sorties, sliding time and ground support mechanical atmospheric pollutant emissions and environmental impacts.however, only simple qualitative analysis of aircraft exhaust, can’t influence the scope and degree of, don’t put forward effective control measures, not only can not meet the requirement of the competent department of environmental protection at the present stage of review, also cannot give a satisfactory answer, the residents along with the people to the airport atmospheric forecast calls for quantitative calculation is higher and higher, how to visually show the airport atmospheric environment the influence extent of the impact of the scope, measures and measures taken by the effect, is the airport project environmental impact assessment must face and solve.To an airport as an example, this paper introduces the technical features of EDMS software, and the quantitative calculation method in the atmosphere at the airport, from the sensitive point, the grid point and within the scope of the airport, the largest concentration of location part three discusses the aircraft exhaust to the surrounding environment air quality the influence degree and range, on this basis, the author analyzes the reasons for overweight and put forward effective mitigation measures, and the measures, the pollutant concentration change before and after the comparative analysis of environmental impact assessment of air pollution forecast in the airport has strong guiding significance in the work.
