Abstract：Benzene series is a common industrial pollutant,which includes benzene,methylbenzene,xylene and styrene.The traditional methods of treating the pollutants include liquid absorption-stripping,adsorption,incineration,condensation method and biological treatment,whose advantages and disadvantages are analysed.A new method of plasma technology is then put forward,which enjoys the characteristics of fast reaction to environmental conditions,wide applications,compact system and easy operation,as well as the advantage of short residual time,thus the plasma technology is suitable to be applied to deal with the volatile organic compounds (VOCs).In this paper,experiment device of different types has been studied and analyzed,which is used to decompose benzene series,and the effects of related parameters have been analyzed,such as applied voltage,electric strength,specific dissipation energy,reactor type,reactor size,carrier gas,residual time and the kind of benzene series,for example,the catalyst could increase the decomposition efficiency and optimize reaction conditions.In addition,the decomposition mechanisms of benzene,xylene and styrene have been discussed and concluded.At last,the combination of plasma technology and traditional methods would be the main study direction of purifying VOCs in the future.
