Resource utilization of modified metallurgical slag, as an important solution for solid waste disposal in metallurgical industry, shows significant potential for application in wastewater purification and treatment. This paper reviewed research progress on enhancing adsorption and catalytic properties of modified metallurgical slag through physical and chemical modification methods, and systematically analyzed the treatment mechanism and efficiency in treating organic pollutants (e.g., aniline, dyes) and inorganic pollutants (e.g., heavy metals, phosphates). The study showed that the modified metallurgical slag can efficiently remove pollutants from water by virtue of its porous structure, abundant active sites and surface chemical properties, realizing the environmental protection goal of 'treating waste with waste'. The technology had advantages such as low cost, high stability and low risk of secondary pollution, providing an innovative solution for the green transformation of water treatment industry and resource recycling. In the future, it is necessary to further optimize the modification process and to explore strategies for synergistic management of multiple pollutants.
