Study of the Treatment of Organic Waste Gas Containing Benzene by a Low Temperature Plasma-Biological Degradation Method

Volatile organic compounds (VOCs) from the pharmaceutical and chemical industries have been a matter of concern for some years in China. Achieving efficient degradation chlorobenzene (CB) waste gas is difficult because its high volatility molecular stability. A DBD (dielectric barrier discharge) biological method was proposed to treat chlorobenzene, aiming control operating costs prevent secondary pollution. In this investigation, introduced deal with by optimization process parameters. The results showed that efficiency close 80% at hydraulic retention time (HRT) 85 s when inlet concentration 700 mg·m−3 method. reached under discharge voltage 7 kV, an HRT 5.5 s. integrated system can be increased 15–20% compared single system. Therefore, used as new way address pollution industries.
