On the basis of the review and summary of the development history of atmospheric pollutant emission standards in thermal power plants of China, the promoting role and the resulting environmental effects of these standards or requirements in different stages, especially those for ultra-low emissions are analyzed on the development of atmospheric pollution control technologies in coal-fired power plants in China,. At present, the control of atmospheric pollutants in thermal power industry in China is at the stage of ultra-low emission, and the prevention and control technologies of atmospheric pollution in coal-fired power plants is at the leading edge of the world. For the three main conventional pollutants, such as dust, SO2 and NOx, the coal-fired power plants have achieved the state of cleanliness almost the same as the gas-fired power generation. Nevertheless, China's thermal power environmental protection is still facing many other challenges, such as CO2 control, further reductions of regular air pollutants, wet desulphurization effect on ecological environment, disposal of hazardous waste scrap of SCR catalyst, non-conventional pollutants control, operation optimization of flue gas treatment facilities, etc. In this paper, the key areas and corresponding targets for research and development are also put forward.%在对中国火电厂大气污染物排放标准的发展历程进行回顾与总结的基础上,分析不同阶段排放标准或要求对中国燃煤电厂大气污染控制技术发展的推动作用及其产生的环境效果,特别是超低排放.目前中国火电行业大气污染物控制处于超低排放阶段,燃煤电厂大气污染防治技术处于国际领先水平,烟尘、SO2、NOx三大常规污染物排放浓度实现了燃煤发电与燃气发电基本同等清洁.尽管如此,中国火电环保在CO2控制、常规大气污染物进一步减排、湿法脱硫对生态环境的影响、危险废物废弃脱硝催化剂的处置、非常规污染物的控制、烟气治理设施的运行优化等方面仍然面临诸多挑战,提出了需要研发的重点领域及相应目标.
