高炉矿渣资源化利用的研究现状及展望

Research Status and Prospect of Blast Furnace Slag Resource Recycling

钢铁生产行业在高速发展的同时,高炉炼铁工艺产生的高炉渣不断累积。由于缺乏有效的资源化利用方式,高炉矿渣就地堆积,占用了大量土地资源,并对周边的土壤及水体环境造成了污染。有效利用高炉矿渣等二次资源,减少高炉矿渣对环境的污染,达到高炉矿渣的减量化、无害化、资源化处理,并进一步提高高炉矿渣基产品的附加值,是我国钢铁行业可持续发展的有力保障,对于建立环境友好型、资源节约型社会具有促进意义。

With the rapid development of iron and steel industry,more and more blast furnace slag has been generated by the blast furnace iron-making technology.Due to the lack of effective resource recycling ways,blast furnace slag accumulates locally,occupies a lot of land resources,and causes pollution to the surrounding soil and water environment.Effective utilization of blast furnace slag and other secondary resources can reduce the environmental pollution caused by blast furnace slag,achieve the reduction,harmless treatment and recycling of blast furnace slag,and further increase the added value of blast-furnace-slag-based products.Therefore,it is a powerful guarantee for the sustainable development of China's iron and steel industry,and is of great significance to promoting the construction of an environment-friendly and resource-saving society.
