钢铁渣的农业资源化利用

钢铁渣是钢铁冶金生产的主要固体废弃物,开发冶金炉渣的综合利用技术对于防止环境污染和促进冶金工业的长期可持续发展有十分重要的意义.钢铁渣的理化特性进行了简要的介绍,详细论述了其在农业生产上的资源化再利用技术以及施用钢铁渣肥料后的土壤环境效应.钢铁渣应用于农业生产可以使其含有的有益元素得到充分利用,不会对农产品及土壤环境造成危害,而且通过在钢铁渣中加入添加剂合成新型农业肥料可以有效地提高钢铁渣肥料的附加值,更好地满足农业生产的高产和优质的需求.

Utilization of Ferrous Metallurgical Slags as Resource Materials in Agriculture

The waste slags of iron and steelmaking is the main solid waste of ferrous metallurgy, Utilization of metallurgical slags as resource materials is very important for preventing the pollution of the environment and promoting the continous development of metallurgical industry. This paper briefly introduces the physical and chemical characteristic of iron and steelmaking slags and details the technology of its utilization as resource materials in agriculture and its effects to soil environment. The application of mtallurgical slags in agriculture can make full use of the beneficial elements in slag and doesn't harm to farm products and soil environment. Moreover, the new fertilizer produced from slag through added additive can effectively promot the additional value of the product and satisfy the need of high yield and quality in agriculture.
