活性炭作为典型吸附材料在国民经济各领域有着广泛的应用。大量废弃活性炭的再生回用,既可减少原生炭生产过程中的原料消耗与 CO2 排放,又能有效降低企业用炭成本,同时避免传统炭焚烧填埋处置对环境造成的负面影响,符合国家鼓励的资源循环利用战略。因此,如何实现废活性炭的经济高效再生,已成为活性炭产业高质量发展与资源循环利用过程中亟待解决的关键问题
废活性炭热再生法,因技术普适性强、再生效率高的优势,成为当前主流活性炭再生工艺。在“打赢蓝天保卫战”“建设无废城市”等相关大气污染治理政策的推动下,我国已建成多个区域性废活性炭集中再生项目。然而,已投运的废活性炭再生设施普遍面临废活性炭收集难度大、运行负荷低下、再生效率低且能耗高、再生炭品质欠佳等现实问题。在国内经济社会全面绿色转型的大背景下,亟需科学规划、建设技术先进、运行可靠的废活性炭综合性集中再生设施,推动其资源循环利用迈向高质量发展新阶段。
1产业现状与存在的问题
1.1产业技术特征
废活性炭因其来源广、理化性质复杂,广泛应用于化工、医药、食品加工、环境保护(含污水处理、空气净化、VOCs治理)贵金属冶炼、新能源材料等领域。现有废活性炭再生技术包括热再生、化学再生、生物再生及超临界氧化等,其技术核心在于通过物理、化学、热化学等工艺实现吸附质脱附,从而恢复其吸附性能。……
