Abstract
Emissions of VOCs in China,the United States and the European Union in recent years are analyzed.The ways to control VOCs are outlined.At present,end treatment is the main measure to control VOCs.The recycling technology and destruction technology among end treatment technologies are introduced in detail.Typical techniques such as adsorption,absorption,combustion,biological treatment and photocatalytic degradation are focused on.The principle,advantages and disadvantages,research status and development prospects of these technologies are analyzed,which provides a basis for the selection of VOCs treatment technologies.The adsorption process is mature and widely used.Both the regenerative combustion and catalytic combustion technologies show a high purification efficiency.Photocatalytic degradation and low temperature plasma technologies are emerging technologies.The future development trend of VOCs treatment technology is shared.
