Analysis and prospect on treatment technologies of industrial volatile organic compounds

Volatile Organic Compounds （VOCs） are one of the main sources of atmospheric pollutants. The existing industrial VOCs treatment technologies are classified and reviewed. The working principle,technical characteristics,application scope and current status of main methods of the technologies are summarized,including recycling technologies （such as absorption,adsorption,membrane separation and condensation）,non-recycling elimination technologies （such as thermal oxidation combustion,biodegradation,low-temperature plasma and photocatalysis） and typical combination and integration technologies for industrial VOCs treatment. It is pointed out that the combination and integration treatment technology is the development direction of this field in future.
