煤电减排对中国大气污染物排放控制的影响研究

对中国煤电行业SO_2、NO_x和烟尘的减排历程进行了回顾,系统分析了全国煤电行业不同污染物控制设施装机容量和污染物排放的发展情况,以及全国分行业大气污染物排放的总体发展情况。研究表明,煤电行业近年来的污染物排放控制对中国大气污染物减排贡献巨大。目前中国大气污染物排放的主要源头已由煤电行业转移到热力、钢铁、水泥等高能耗行业。建议制定协同控制高耗能行业的排放标准,加强非电行业的污染物减排管理,集中解决环境污染的主要矛盾。

Study on the Effects of Emission Reduction in Coal-Fired Power Industry on China's Air Pollutant Emission Control

This paper briefly reviews the progress of the emission control over SO₂, NO_x and dust in China's coal-fired power industry and systematically analyzes the development of the installed capacity of emission control devices and situation of pollutant emissions in the coal-fired power industry, as well as the general situation of air pollutant emissions categorized by different industries nationwide. It is concluded that the coal-fired power industry has made remarkable contributions to China's air pollutant control in recent years. At present some energy-intensive industries, such as heat supply, iron and steel manufacturing, and cement etc. have overtaken the coal-fired power industry as the major air pollutant emission sources. Therefore, it is suggested to establish a coordinated emission control standard for these energy-intensive industries so as to strengthen the pollutant control management and focus on resolving the critical issues in environment pollutions.
