拜耳法赤泥脱硫概述

The Summary of the Desulfurization Process with Bayer Red Mud

介绍了大气中硫的污染及国内外脱硫技术,分析了各种技术的处理现状。结合拜耳法赤泥的性质,阐述了拜耳法赤泥吸收含硫废气的研究现状。经过吸收SO2、SO3、H2S改性后的赤泥,更易于开发利用,能大量作为建筑、铺路材料,达到"以废治废、变废为宝、综合利用"的目的。

The pollution of sulfurous gas and the desulfuration technology at home and abroad was introduced, and the treatment of all technology in the present were analyzed. Combined with the properties of the Bayer red mud, the research status mud absorption of sulfurous gas emissions with the Bayer red was explored. Bayer red mud after absorbing SO2, SO3, and HeS can be developed and utilized easily, can be used as the materials of building and paving in a great quantity, and to achieve the purposes of ＂treating waste by waste, changing waste into usage and comprehensive utilization＂
