环境中VOCs的污染现状及处理技术研究进展

Pollution Situation of VOCs in Ambient Air and Research Progresses of VOCs Treatment Technologies

综述了近十年来大气环境中挥发性有机物(VOCs)的污染现状及其主处理技术的研究进展。介绍了目前大气环境中VOCs的主处理技术(包括吸附、冷凝及膜分离等回收技术和燃烧、等离子体、光催化降解和生物降解等销毁技术)的适用条件、经济性、可操作性和净化效率。提出对VOCs的吸收和生物降解的反应动力学模型、催化机制、材料的性能及微生物活性进行深入研究的建议。

The pollution situation of VOCs in ambient air in the last decade and the research progresses of VOCs treatment technologies are summarized. The application conditions, economical efficiency, feasibility and purification efficiency of the main treatment technologies, including adsorption, condensation and membrane separation for VOCs recovery, and combustion, plasma treatment, photocatalytical degradation and bio-degradation for VOCs destruction, are introduced. It is proposed that further research on adsorption and bio-degradation kinetics models, catalytic mechanism, material performance and microbial activity for VOCs treatment should be carried out.
