Air pollution effect of the thermal power plants in Beijing-Tianjin-Hebei region

Since there haven't been any research on the explicit analysis of the air pollution of thermal power plants in Beijing-Tianjin-Hebei region, we conducted this research to complement the great need, which was based on the power plants' emission datum consisted of CEMS, EIA, as well as follow-up inspection. With these datum we built the bottom-up emission inventory of all thermal power plants in Beijing-Tianjin-Hebei region. Making use of the WRF output data, we simulated the meso-scale meteorological field by CALMET. Then we simulated the air pollution effect of SO2, NOx, primary PM10, sulfates, nitrates under different scenarios. The simulation result showed that: In 2011, the most affected subarea of the air pollution of thermal power plants was the Southwest part of the region, the highest annual average pollutants emission records was held by Shijiazhuang. After the emission reduction action has been taken, the total amount of SO2, NOx, PM10 emitted from the thermal power plants has respectively reduced 33%, 71%, 68% of those in 2011. Another gratifying result was that the annual average concentration of SO2, NOx, primary PM10, sulfate, nitrate caused by the power plants has reduced to respectively 46.34%, 78.43%, 76.34%, 39.49%, 73.87%, significantly lower than those before the emission reduction action has been taken. ©, 2015, Chinese Society for Environmental Sciences.
