A novel microwave plasma system was implemented and applied on the volatile organic compounds (VOCs) treatment. Ethanol and acetone were selected as the target VOCs respectively. The decomposition and removal efficiency (DRE) value was used to evaluate the performance of the microwave plasma system. Oxygen, air and H2O add to air were used as carriers to combine with the VOCs and to facilitate the VOCs treatment. Under the optimal conditions, namely, flow rate of ethanol was 1500 sccm, power input was 1.5 KW at a frequency of 1KHz, flow rate of air was 1000 sccm and the flow rate of H2O was 0.3 ml/min, an efficiency high than 97% DRE value could be obtained for both ethanol and acetone. Due to the high efficiency and high capacity, this system could be an potential alternation in industrial VOCs treatment.
