Research On Diffusion Of Atmospheric Pollutants And Air Quality Control In Yangquan City

In intensive research,it was found that Yangquan city was in the conditions ofspecial geomorphic features with west valley and eastern basin in mountains and itstrapped buiit-up area,and special climate with higher frequency of calm wind,moreprone inversion layer,partial W winds prevailed throughout the year,prevalent partialE wind in summer which speed is smaller,and weather situation for summer rainfallbelonging to Northern Trough and Southern Vortices,etc. The pollution sources ofresource-based business,coal gangue hills and hilly city’s motor vehicle exhaustreflected the particularity of pollutants. By the use of monitoring data for years andmulti-sources diffusion models for mountain-valley city, after the macro-comparingand micro-analysis,it was revealed that The diffusion field of atmospheric pollutantsbelonged to uneven,complex and unfavorable diffusion one in urban areas for thecompound of special surface feature,climate, pollution sources, and other factors,withapparent separation and partition. Imitating atmospheric pollution diffusion situationsin Yangquan-city in2006-2010reached pollutants diffusion rules of pollution sourcesin separation and partition.The optimization system of all control methods of airquality was proposed on the basis of Total quantity control and decrease pattern ofpollutants discharges, control and reduction method of pollutants by monitoringacid rain and by real-time monitoring PM2.5.
