我国燃煤电厂“十二五”大气污染物控制规划的思考

Thinking about the Twelfth Five-Year Planning of Air Pollutants Control for China's Coal-fired Power Plant

"十一五"期间,我国电力行业燃煤电厂的大气污染物控制取得了很大成就。我国电力行业大气污染物控制处于世界先进水平。尽管火电装机容量在这段时间增长了10倍以上,但烟尘排放总量略有下降;SO2控制取得明显成效,为全国完成节能减排目标做出了决定性的贡献;NOx控制初见成效,烟气脱硝工程开始建设。"十二五"时期,电力行业大气污染控制任务将以NOx控制为主,在电力行业"十二五"大气污染物控制规划中,应坚持源头控制和末端治理相结合,坚持以重点污染物控制为导向,以最佳经济可行技术为导向的原则,主要控制指标应分层级考虑并纳入国家规划、国家环保规划和电力环保规划之中。在电力行业大气污染控制措施上,应积极转变电力发展方式,强化技术引导,加强基础工作,坚持科技与管理创新,提高管理水平。

During the Eleventh Five-Year Plan period, great achievements of coal-fired power plant air pollution control in China＇s power industry, which had reached the world advanced level, had been made. Despite more than 10 times growth of thermal power installed capacity during the period, dust emissions remained a slight decrease; sulfur dioxide control made remarkable achievements, having made a decisive contribution to the national energy conservation and emission reduction targets; nitrogen oxide control made preliminary outcomes and flue gas denitrification projects had been in construction. During the Twelfth Five-Year Plan period, the main tasks of air pollution control in power industry will turn to nitrogen oxide control. In the planning, some principles should be considered as follows： source control and end-of-pipe treatment should be combined; key pollutants control and the best availability technologies should be insisted as a guide; key control indexes should be considered at different levels and written into national planning, national environmental protection planning and power industry environmental protection planning. In respect of air pollution control measures, it is necessary to change development mode of power, strengthen technical guidance and basic work, adhere to the technology and management innovation, and improve the management level.
