电解锰渣建材资源化研究现状与展望

电解锰渣已成为制约电解锰行业发展的瓶颈问题，建材可以实现电解锰渣的大规模消纳，但电解锰渣含水率高导致其氨氮和可溶性硫酸盐处理处置难，目前尚无经济稳定运行的工业化案例。为实现电解锰渣建材资源化，本文系统疏理了电解锰渣理化特性、生态环境特征、减量化和无害化现状，重点分析了近年来电解锰渣建材资源化研究现状以及产业化应用实施案例，结合目前的经济、技术和市场因素，探讨了电解锰渣制备水泥混合材和蒸压加气混凝土的可行性，以期为解决电解锰渣资源化利用与无害化处理提供新的思路，从而推动电解锰行业的可持续发展。

Current status and future prospects of electrolytic manganese residue reused as building materials

Electrolytic manganese residues (EMRs) significantly blocked the development of electrolytic metal manganese industry. Although building materials could efficiently reutilize these EMRs in large-scale, no economically and stable running cases could be found in the market because of NH{}_{\mathrm{4}}^{+}-N and soluble sulfates caused by its high-water content. To better EMRs reutilization in building materials, first, its physical/chemical properties, eco-environmental characteristics, reduction and decontamination methods were reviewed. Then, the research status and perspectives of EMRs for building materials as well as their industrialization implementation cases were discussed. Finally, the feasibility of EMRs for cement mixture and autoclaved aerated concrete were analyzed, aiming to provide a new idea for EMRs reuse and decontamination and to ensure the sustainable development of electrolytic metal manganese industry.
