Abstract:

In recent years, the problem of air pollution and haze have become more and more serious. Volatile organic compounds(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 organic 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.

Key words: waste gas, volatile organic compounds(VOCs), processing technic, research progress
