挥发性有机物(VOCs)严重危害人体健康及大气环境,而吸附工艺具有VOCs去除效率高、成本低等种优势并在VOCs的治理中发挥着重要作用,其核心在于VOCs吸附功能材料研制,因而基于活性炭具有原料来源广泛、孔隙结构发达、可回收利用等优点则常作为吸附剂被应用于VOCs治理。综述活性炭吸附工艺在VOCs治理领域的研究及技术应用进展,阐述活性炭吸附VOCs的关键影响因素及改性方法,并总结当前活性炭吸附VOCs的工艺技术、再生方法及应用现状,旨在为活性炭的选择及工艺控制提供理论指导。在活性炭选择上,应根据VOCs性质及外部工况选择具有合适结构的活性炭,同时须开发具有疏水性质的活性炭。在实际应用中,开展多种吸附工艺耦合为未来VOCs吸附工艺发展的重要方向;但由于VOCs成分的复杂性,可根据实际合理选择1种或多种VOCs治理工艺与吸附工艺联用以保证治理效果。对于吸附VOCs至饱和的活性炭,应从经济性及再生效果等方面进行考量从而对活性炭进行合理再生、补充或更换。

VOCs are seriously harmful to human health and the environment. The adsorption process has various ad⁃vantages such as high VOCs removal efficiency and low cost, and plays an important role in the treatment of VOCs,the core lies in the development of VOCs adsorption functional materials. Due to the wide range of raw materialsources, developed pore structure, and recyclability, activated carbon is often used as an adsorbent in VOCs treat⁃ment. This article reviews the research and application progress of activated carbon adsorption technology of VOCstreatment, elaborates on the key influencing factors and modification methods of activated carbon adsorption of VOCs,and summarizes the current process technology, regeneration methods, and application status based on practical ap⁃plications, aiming to provide theoretical guidance for the selection and process control of activated carbon. In productselection, suitable structures should be chosen based on the properties of VOCs and external operating conditions,and it is necessary to develop activated carbon with hydrophobic properties. In practical applications, coupling multi⁃ple adsorption processes is an important direction for the future development of VOCs adsorption processes. However,due to the complexity of VOCs components, one or more VOCs treatment processes can be reasonably selected basedon actual conditions to ensure treatment effectiveness. For the activated carbon that adsorbs VOCs to saturation, rea⁃sonable regeneration, supplementation or replacement of activated carbon should be carried out from the perspectiveof economy and regeneration effect.
