Based On The AERMOD Model Under Complex Terrain Atmospheric Industrial Source Pollution Simulation And Assessment

Atmospheric environmental pollution in recent years become one of the pollutionproblem of the countries in the world today, especially in industrial source because of itsgreat range, emissions, processing efficiency in the current economic and technologicalconditions is difficult to improve the features have to concern for people, especially thecomplex terrain atmospheric pollution in the air environment contribution value is moreand more big, the unique terrain conditions and under special meteorological environmentair pollution problem is particularly prominent.Now, our country attaches great importanceto the atmospheric pollution problem, how to use the correct pattern reflect atmosphericpollutant contribution value problems become a top priority, have conducted a lot ofresearch work.For baishan HunJiang district six river valley in the town of geomorphic features, thejilin baishan city HunJiang area low grade hematite efficient processing recycling andcomprehensive utilization of strong demonstration project of air pollution has carried onthe system of investigation and research, mastered the basic information of regionalatmospheric environment;For information construction of the study area needed byAERMOD model terrain database and meteorological database, according to the content,and forecasting scenario for the study area prediction scheme, finally predict pollutionsources of regional environment, the influence of atmospheric environmental pullutionassessment, for environmental protection in the study area control management to providedecision-making basis.Through field investigation and data collection, complete AERMOD basic informationinvestigation and study, completed the baishan HunJiang district six river town ofmeteorological data, terrain data survey;For atmospheric environmental background valuein study area, the distribution of the sensitive data and investigation, calculated areaatmospheric environment contribution value, superposition and the sensitive predictivevalue.First estimate model is used to calculate the engineering evaluation class atmosphere,reuse AERMOD model to simulate the calculated normal condition and abnormalconditions of typical hours, a typical day, long-term weather conditions, engineering airsensitive to the environment and the influence of the evaluation scope as well as themaximum impact;Overweight, overweight position, and exceed the duration, etc.Through the study of this article, to research on the sources of atmospheric pollutionsources like, strong production, emission source, emissions and environmentalbackground values to conduct a comprehensive grasp, understand its in different weatherconditions, terrain conditions, and the dynamic change of different operatingconditions.Provide guiding significance for the region sensitive protection, ensure thesecurity of sensitive atmosphere, make control plan and actual management measures toprovide important support.
