含镁材料生产现状与在环保中的应用

Production of Mg-containing materials and research progress on the applications in environmental protection

对含镁材料生产现状及其在环保领域中的应用进行了评述。包括轻烧氧化镁、合成氢氧化镁、水镁石、水菱镁石———斜方云石和菱镁矿等的生产能力,含镁材料在烟气脱硫工业废水处理,工业液体排放物中重金属离子、非金属离子、有机物和相关着色物质的脱除,矿物型镁质阻燃剂,二氧化碳固定封存以及其他方面的应用。探讨了发展前景。

A review on the production status of magnesium-containing materials and its applications in environ mental protection is given in this paper. Production capacities of caustic calcined magnesia, synthetic magnesium hy- droxide,brucite,hydromagnesite-huntite and magnesite are introduced. Applications of magnesium-containing mate rials in flue gas desulfurization（FGD）, industrial wastewater treatment, reoval of heavy metal ions, nonmetalions, or ganic and colored matter in industrial emission liquors, mineral-type magnesian flame retardant and seqestration of carbon dioxide as well as others are reviewed. Their development foreground was prospected.
