我国煤电大气污染物控制现状及展望

"十二五"以来,我国煤电大气污染物的控制取得了很大的成就,烟尘、二氧化硫、氮氧化物排放总量和强度快速下降,控制水平达到世界先进水平。"十三五"乃至更长时期,煤电仍将承担国家大气污染物减排的重任。重点研发高性能、高可靠性、高适用性、高经济性污染物的控制技术、资源化技术、多污染物协同控制技术是未来我国煤电大气污染物控制的主要技术方向。预计到2020年,烟尘、二氧化硫、氮氧化物年排放量分别降至2×10~5~3×10~5 t、1×10~6~1.5×10~6 t、1×10~6~1.5×10~6 t。

Current Situation and Prospect of Control on Air Pollutants from Coal-Fired Power in China

Since 2011, China has made great achievements on the control of air pollutions from coal-fired plants. The total amount and intensity of air pollution emission including dust, sulfur dioxide and nitrogen oxide declined rapidly. The technology of emission control has reached the world level. In the 13th Five-Year Plan and even a longer period, coal-fired power plants will still take on heavy responsibility of the atmospheric pollutants emission reduction. Pollutants-control technologies of high performance, high reliability, high applicability and high efficiency, resource recovery technologies and cooperative control technologies of multiple pollutants are the main research directions of air pollution control technology of plants in China in the future. By 2020, the expected annual amount of emission of dust, sulfur dioxide and nitrogen oxide from coal-fired power will reduce to 2×105~3×105 t, 1×106~1.5×106 t, 1×106~1.5×106 t, respectively.
