摘　　要：钢铁行业作为我国经济发展的支柱产业,它所引起的环境问题也不容小觑。钢铁烧结烟气中通常含有大量SO_2和NO_x,是造成酸雨以及其他环境问题的主要原因。目前针对SO_2已有较成熟的脱除工艺。而由于我国烧结烟气的特殊性,还没有特别适用于NO_x的处理工艺。介绍了几种典型的和未来极具市场潜力的脱硝技术,为今后脱硝工艺的选择提供一些借鉴。Iron and steel industry played an important role in China＇s economic development,but it also caused some serious pollution. The tremendous SO_2 and NO_x emission caused acid rain and other environmental problems. There were already some mature techniques for desulfurization. Since the unique chatacteristics of the slue gas of China＇s iron and steel industry,few technology was proved to be perfectly suitable. Some typical De NO_x technologies and potential De NO_x technologies were introduced. The direction of future development was previewed.
