摘要
近年来我国大气污染和雾霾问题越来越严重。挥发性有机物(VOCs)是造成大气污染的主要原因之一,而工业有机废气是VOCs的主要来源。因此,采取必要的措施来减少有机废气的排放迫在眉睫。国内外处理有机废气的技术包括吸附、吸收、冷凝、膜处理、催化氧化、等离子体、生物等,本文总结了这些技术的特点、使用条件、应用案例和效果等。最后总结出目前上述技术所存在的弊端,并指出其今后的发展方向。
In recent years, the problem of air pollution and haze have become more and more serious. Volatile organic com- pounds （VOCs） is one of the main source of air pollution,while industrial organic waste gas is the main source of VOCs. Therefore, taking necessary measures to reduce emissions of organic waste gases is imminent. Technologies to deal with or- ganic waste gas at home and abroad, including adsorption, absorption, condensation, membrane treatment, catalytic oxidation, plasma, biological treatment are introduced in the article. The technical characteristics, use conditions, application cases and treatment effect of these technologies are covered. Finally, the weakness of the above technologies are indicated, the direction of future research in these technologies for air pollution applications are also showed clearly in detail.
