摘要

摘要: 电石渣作为氯碱工业制乙炔过程产生的碱性工业固废，长期堆存会引发严重生态环境风险，亟待高效资源化处置。系统综述了电石渣矿化固定二氧化碳的技术路径与应用进展，基于其Ca（OH）₂主导的高活性物相特征，阐释气-固/液-固直接碳化与铵盐循环浸取-碳酸化间接碳化的反应机制；通过工艺参数调控、氨基酸改性及多固废协同等策略优化矿化过程，显著提升反应效率与产物性能，实现了高附加值碳酸钙产品的可控合成；对矿化产物的环境与经济效益分析，证实该技术在实现CO₂固定的同时，具备良好的经济可行性。电石渣CO₂矿化过程同步达成固废资源化与碳减排目标，衍生的轻质填料及低碳胶凝材料兼具环境效益与经济潜力，为“以废治废”型碳减排技术体系提供了理论与应用支撑。

Abstract: As an alkaline industrial solid waste produced in the process of acetylene production from the chlor-alkali industry， the long-term storage of carbide slag poses serious ecological and environmental risks， which urgently require efficient disposal. In this paper， the technical pathways and application progress of carbon dioxide fixation by carbide slag mineralization are systematically reviewed. Based on the high-active phase characteristics dominated by calcium hydroxide， the reaction mechanisms of gas-solid/liquid-solid direct carbonization and ammonium salt cyclic leaching-carbonation indirect carbonization are elaborated. The mineralization process has been optimized through process parameter regulation， amino acid modification， and multi-solid waste coordination， which significantly improves reaction efficiency and product performance and enables the controllable synthesis of high-value-added calcium carbonate products. The analysis of the environmental and economic benefits of the mineralized products confirms that the technology exhibits good economic feasibility while achieving CO₂ fixation. The CO₂ mineralization process of carbide slag synchronously achieves the dual goal of solid waste resource utilization and carbon emission reduction. The derived lightweight fillers and low-carbon cementitious materials possess both environmental and economic potential， which provides theoretical and application support for the “waste-to-waste” carbon emission reduction technology system.
