摘要
二氧化硫和氮氧化物主要来源于烟气。烟气处理是环境保护的重要任务。叙述了传统的湿式烟气脱硫和氨选择性催化还原组合脱硫脱硝的优缺点,介绍了几种烟气同时脱硫脱硝的技术及其最新进展,分析了它们的原理、特点和应用。
Sulfur dioxide and nitric oxides are mainly derived from flue gas, and the flue gas treatment is one of the important missions of environment protection.The advantages and disadvantages of the traditional methods which remove SO_2 and NO_x from flue gas by wet desulfurization and NH_(3) selected catalytic reduction are described.Some technologies for combined control of SO_2 and NO_x are introduced concerning their current progress, basic principle, process characteristics and applications.
