钢渣与污泥协同资源化研究进展

Synergetic Resource Utilization of Steel Slag and Sludge and It’s Research Progress

钢渣和污泥作为传统大宗固体废弃物,始终面临处理成本高、回收利用率低等问题,但其内部含有大量可利用物质,具有较高的资源化利用价值,现已成为国内外的研究热点。为了提高钢渣与污泥绿色、高效、协同资源化利用,综述了近年来国内外钢渣在建筑、道路、水处理、农业等领域资源化利用的研究进展,立足固废无害化、减量化,从钢渣和污泥的资源化进行分析与总结,指出不同研究方法的特点和优劣,为固废资源化利用提供参考。并基于我国发展现状对钢渣与污泥资源化利用的未来发展方向进行了展望,以期为固废处理行业的良性发展提供一定的理论支撑。

Steel slag and sludge, as traditional bulk solid wastes, have always faced problems such as high treatment cost and low recycling rate, but they contain a large amount of usable substances and have high resource utilization value, and have become research hotspots at home and abroad. In order to improve the green, efficient and synergistic resource utilization of steel slag and sludge, this paper reviews the domestic and foreign research progress in steel slag resource utilization for construction, road, water treatment, agriculture and other fields in recent years, analyzes and summarizes the resource utilization of steel slag and sludge, points out the characteristics and advantages and disadvantages of different research methods, and provides a reference for the utilization of solid waste resources. And based on the development status of our country, the future development direction of steel slag and sludge resource utilization is prospected, in order to provide certain theoretical support for the sound development of the solid waste treatment industry.
