摘要： 采用全溶实验、短期与长期浸出实验，对电炉精炼渣中重金属元素的浸出行为进行研究，并通过SEM与XRD分析其机理. 结果表明，电炉精炼渣中Ba元素短期浸出浓度最高值为52.10 mg/L，超出国家污水重金属排放标准；Ni元素短期浸出浓度最高值为0.025 mg/L，V元素长期浸出浓度最高值为0.176 mg/L，超出生活饮用水卫生标准. 重金属元素的浸出主要是由于钢渣中Ca2SiO4×H2O (C-S-H)等结构的破坏.

Abstract: The leaching behaviors of heavy metals in electric furnace refining slag were studied by total dissolving, short-term and long-term leaching experiments, and the leaching mechanism was analyzed by SEM and XRD. The results show that in the slag, the concentration of Ba from short-term leaching is higher than the discharge standard of wastewater containing heavy metal, and the concentrations of Ni from short-term leaching and V from long-term leaching are higher than the hygiene standard of domestic and drinking water. Leaching of heavy metals is mainly due to the structural damage of Ca2SiO4×H2O (C-S-H) in the slag.

Key words: electric furnace refining slag, heavy metal, leaching
