With the development of industrial production, the emission of volatile organic compounds and pollutant components continue to increase. A variety of technologies and processes for treatment of VOCs have emerged. This paper briefs the typical characteristics of VOCs, summarizes and compares corresponding physical, chemical and biological treatment technologies, and summarizes in detail the treatment technologies such as adsorption, plasma and biological methods. The traditional treatment technology has low cost, mature technology and large processing capacity, but it can not meet the current situation of industrial production, especially decomposition of a variety of mixed polluting gases. Emerging technologies and combined technologies have the advantages of high purification efficiency, no secondary pollution and low energy consumption, which will be a continuous research hotspot in the future. By analyzing the current emission characteristics of VOCs and the corresponding treatment technologies, this paper discusses the most significant advantages and disadvantages of each technology as well as the difficulties that need to be overcome in the future. Finally, the future improvement direction and trend of VOCs treatment methods are put forward.
