摘要: 针对电解锰渣资源利用率低以及堆存带来的污染问题,本研究以未脱硫电解锰渣、废玻璃和高岭土为 基材,结合造孔剂添加—压制成型—常压烧结工艺制备多孔陶瓷材料。 通过正交试验优化原料配比与工艺参数,确 定当粉煤灰添加量为 15%、原料(锰渣、废玻璃与高岭土)质量比为 3 ∶6 ∶1、成型压力 10 MPa、烧结温度 975 ℃ 时,所得 到的材料综合性能最优,其抗压强度达 214 MPa,体积密度为 1. 83 g / cm 3 ,Pb 2+吸附量 7. 79 mg / g。 进一步的吸附试验 表明,在 pH= 1. 5、Pb 2+初始浓度为 100 mg / L、温度为 25 ℃ 、振荡速率为 170 r/ min 条件下反应 540 min,多孔陶瓷材料 对 Pb 2+的吸附量和去除率分别为 7. 86 mg / g 和 87. 70%。 该研究为电解锰渣的资源化利用提供了新思路,有效实现了 固废协同处置与重金属污染治理的双重目标。

Abstract: In order to address the low utilization rate and severe storage pollution of electrolytic manganese residue (EMR),this study developed porous ceramic materials using non-desulfurized EMR,waste glass,and kaolin as raw materials through a pore-forming additive addition, press forming, pressureless sintering process. Through orthogonal experiments to optimize the raw material ratios and process parameters,it was determined that when the addition of fly ash was 15%,the mass ratio of raw materials (manganese slag,waste glass and kaolin) was 3 ∶6 ∶1,the molding pressure was 10 MPa,and the sintering temperature was 975 ℃ ,the resulting material had the best overall performance,with a compressive strength of 214 MPa,bulk density of 1. 83 g / cm 3 ,and the adsorption capacity of Pb 2+ of 7. 79 mg / g. Further adsorption experiments showed that the adsorption and removal of Pb 2+ by the porous ceramics reached 7. 86 mg / g and 87. 69%,respectively,when the reaction was carried out for 540 min at pH= 1. 5,initial concentration of 100 mg / L of Pb 2+ ,temperature of 25 ℃ ,and oscillation rate of 170 r/ min. This study provides a new idea for the resource utilization of electrolytic manganese slag,and effectively achieves the dual goals of solid waste co-disposal and heavy metal pollution control.
