摘要

由于工业生产过程中的成本和环境污染问题，大量有害有机废物的管理面临着巨大挑战。制定回收利用此类废物的通用策略对环境保护至关重要。本文提出了一种基于反应的高价值重酚渣废物（HPSW）回收和循环利用策略。在分析 HPSW 的化学结构后，采用缩聚法将 HPSW 通过酚羟基与甲醛的反应转化为活性炭粘合剂（ACA）。新制备的活性炭样品（AC-12，在最佳条件下）的碘值高达 1320.80 mg-g-1，比表面积为 1368.8 m2-g-1。它能高效吸附气相（对二甲苯蒸气）和液相（亚甲基蓝）中的有机污染物，平衡时间小于 15 分钟，达到了高端商用活性炭的标准。这种既环保又经济的方法为各类有机废弃物的资源化回收和处理提供了创新途径，有利于工业中有害有机固体废弃物的有效利用和处置。

Low-carbon and high-value utilization of hazardous industrial organic waste: From molecular mechanism to application

The management of large volumes of hazardous organic waste poses remarkable challenges due to costs and environmental pollution in industrial processes. Developing a universal strategy for recycling such waste is crucial for environmental protection. Herein, a reaction-based strategy has been proposed to recover and recycle the heavy phenolic slag wastes (HPSW) in a high-valued way. After analyzing the chemical structure of HPSW, the polycondensation method has been used to convert HPSW into an activated carbon adhesive (ACA) through reaction between phenolic hydroxyl groups and formaldehyde. The newly prepared activated carbon sample (AC-12, at optimal conditions) exhibited a high iodine value of 1320.80 mg·g⁻¹ and a specific surface area of 1368.8 m²·g⁻¹. It demonstrates high efficiency in adsorbing organic pollutants from both gaseous (p-xylene vapor) and liquid phases (methylene blue), with an equilibration time under 15 min, achieving the standard of high-end commercial ACs. This environmentally friendly and cost-effective method offers innovative approaches for the resourceful recycling and treatment of various types of organic waste, facilitating the efficient utilization and disposal of hazardous organic solid wastes in industries.
