燃煤电厂污染物超净排放技术探究

Research on Ultra Clean Emission of Pollutants in Coal-fired Power Plants

空气污染已经成为我国面对的主要环境问题之一,尤其是雾霾等大气复合污染,严重影响了人们的正常生活、工作、学习和身体健康。北方的很多城市,见到蓝天白云成为了一种奢侈。而燃煤电厂的SO2、NOx以及烟尘等排放是形成PM25的重要原因。因此燃煤电厂的污染物排放治理成为我国大气治理的关键部分。目前比较成熟有效的治理方案就是"超净排放"的应用,可以最大程度的减少污染物排放。文中探讨了超净排放技术,系统地总结各种技术特点,更好地为燃煤电厂发展做出贡献。

Air pollution has become one of the main environmental problems in China,especially air pollution such as fog and haze.It seriously affects people＇s normal life,work,study and health.In many cities in the north,it has become a luxury to see blue sky and white clouds.The emission of SO2,NOx and smoke from coal fired power plants is an important reason for the formation of PM25.Therefore,the pollution control of coal-fired power plants has become a key part of the air control in China.At present,the more mature and effective management scheme is the application of ＂super net emission＂,which can reduce the emission of pollutants to the maximum extent.In this paper,the former super net emission technology was discussed,and various technical features were summarized systematically to contribute better to the development of coal-fired power plants.
