摘要 "十二五"期间我国相继实施了世界最严控制水平的GB 13223-2011、煤电超低排放政策,2016年火电行业烟尘、SO_2、NO_x平均排放强度比2010年分别下降约84%、86%、87%,在发电量增长约25%的情况下,烟尘、SO_2、NO_x排放总量分别降低约125万t、756万t、795万t,为完成全国主要污染物减排目标做出最大贡献。通过贯彻GB13223-2011,火电行业对典型以煤为主的省级区域地级市市区的环境空气PM_(2.5)贡献基本控制在30%以下,腾出了可持续发展的大气环境容量;通过实施煤电超低排放政策,火电行业对典型区域地级市市区的环境空气PM_(2.5)贡献基本在15%左右,火电行业可以适应未来更高的环境质量控制要求。火电行业对城市环境空气质量的影响总体较小,在深化火电行业NO_x等大气污染物减排的同时,还应进一步强化非电行业VOCs等污染物协同减排,才能实现环境空气质量全面改善目标。 During the twelfth five- year plan period in China, G B ] 3223 -20] 1 and the ultra- low emission policy on coal - fired electric utility steam generating units which illustrate the most strict level of control in the world are implemented successively. The emission intensities of dust, SO~, and NO, from thermal power industry in 2016 decline respectively about 84%, 86% and 87% than those in 2010. Under the circumstance that the generating capacity soars approximately 25%, emissions of dust, SO2 and NOx decrease respectively about ]. 25, 7.56 and ?. 95 million ton, which is one of the dominant contributions to complete the emission reduction target on major pollutants in China. In typical provincial region which is coal- based, through the implementation of GB ]323 - 20! ], the contribution of PM2.5 from thermal power industry to atmospheric environment of prefecture - level cit- ies is controlled below about 30%. Accordingly, it makes the atmospheric environment capacity for sustainable development. Based on the implementation of the ultra - low emission policy, the contribution of PM25 to atmos- pheric environment in typical prefecture - level cities is basically contained at about 15%. This serves as a signal that thermal power industry may adapt to higher environmental quality control standards in the future. The influ- ence induced by thermal power industry to atmospheric environment in urban area is generally small. When strengthening emission reduction target of air pollutants from thermal power industry such as NO, , the synergis- tic reduction of emission of pollutants including VOCs from non - electric industry should also be intensified, therefore to comprehensively improve atmospheric environment quality.
