| 摘 要： | 挥发性有机物（VOCs）对环境造成严重污染，危害人体健康，已成为全社会共同关注的环境问题。吸收法作为一种重要的VOCs末端处理技术，具有工艺简单、适应性强、二次污染少、投资运行成本低等优势。吸收剂与吸收设备是制约吸收法处理VOCs效率的关键因素，在介绍VOCs的危害及常见治理技术的基础上，简述4类常用VOCs吸收剂（有机溶剂、表面活性剂、微乳液及离子液体）与2种常用VOCs吸收设备（填料塔与超重力旋转填料床）的最新国内外研究成果，概述VOCs吸收剂再生与重复利用的方法。最后，针对吸收法处理VOCs目前存在的问题，提出了今后的重点研发方向。

| Abstract: | Volatile organic compounds (VOCs) were concerned by the whole society. As a mainstream terminal technology for the removal of VOCs, the absorption method had advantages including simple process, high adaptability, less secondary pollutants, low investment and operation cost. The absorbent and absorption devices were two key factors that constrain the removal efficiency of VOCs by absorption. Based on introducing the harms and common treatment technologies of VOCs, this paper briefly presented recent research results of four kinds of common absorbents (organic solvent, surfactant, micro emulsion and ionic liquid) and two common absorption devices (packed column and high-gravity rotating packed bed) for purifying VOCs containing waste gas globally, and summarized the methods of regeneration and reuse of the absorbents for the removal of VOCs. Lastly, aiming at the existing problems of the absorption method for the removal of VOCs, the key research directions in the future were proposed. |
