A Impact Analysis of Air Quality by Air Pollution Control Facilities Improvement on Point Source Pollution

The object of this study is to identify changes in air pollution in the maximum ground level concentration and the surrounding area when air pollution control facilities are improved in the thermal power plants. The effects of improved facilities are analyzed by comparing air quality after applying improved air pollution control facilities. For prediction of air quality, the change of wind field can be represented with movement of Puff and CALPUFF Model, air pollution diffusion models which can implement abnormal conditions. Major air pollutants of thermal power plants such as SO2, NO2, and PM10 are selected as prediction items. That results show that improvement of air pollution control facilities is significantly effective in reduction of air pollution of SO2 and NO2 in the maximum ground level concentration and areas around of thermal power plants. In the case of PM10, it is found that the effect of reduction in pollution is high in the maximum ground level concentration, but the effect of reduction in air pollution is somewhat low in the area around of the thermal power plant.
