摘要

摘要: 电解锰渣（EMR）是电解锰工业中产生的过滤酸渣，含有大量有害物质，其堆存隐患已成为电解锰行业可持续发展的制约因素。EMR中含有大量SiO₂，故可作为制备EMR基多孔陶瓷等建筑材料的原料，实现无害化资源化处理。以EMR作为陶瓷骨料，以高岭土为黏结剂，研究淀粉和白云石两种不同成孔机制的造孔剂对EMR基多孔陶瓷综合性能和重金属吸附能力的影响，进一步探究复合造孔剂制备EMR基多孔陶瓷的最优工艺参数。结果表明：采用15%白云石和15%淀粉的复合造孔剂制备的EMR基多孔陶瓷，同时具有高气孔率和高抗压强度。研究结果可为开发高性能EMR基多孔陶瓷材料提供工艺和数据参考，进而推动电解锰行业可持续发展。

Abstract: Electrolytic manganese residue （EMR） is a kind of acidic solid waste which generated from filtration process in the manganese electrolysis industry. It contains a large quantity of harmful substances including heavy metals， and exhibits also high acidity. Inappropriate storage of EMR may cause serious environmental pollution. Proper disposal of EMR has become a critical constraint on development of manganese electrolysis industry. EMR contains a large amount of SiO₂， making it suitable as a raw material for producing EMR-based porous ceramics and other building materials， thereby enabling harmless and resource-efficient treatment. This could be a promising technical route to achieve bulk utilization of EMR. In this study， EMR was used as the ceramic aggregate， and kaolin was used as the binder to produce ceramics. The performance of two types of pore-forming agents， starch and dolomite， which have different pore-forming mechanisms was investigated. The porosity， water absorption， bulk density， compressive strength， and heavy metal adsorption capacity of EMR-based ceramics prepared with different binders were compared. Furthermore， the optimal process parameters for producing EMR-based porous ceramics were systematically discussed. The results showed that the EMR-based porous ceramics prepared with a composite pore-forming agent（doped with 15% dolomite and 15% starch） exhibited both high porosity and high compressive strength. These ceramics can be used as building materials or heavy metal adsorbents. The research findings provide valuable insights for developing high-performance EMR-based porous ceramic materials， thereby advancing the sustainable development of the electrolytic manganese industry.
