Abstract We investigate the decomposition of phenol using a hybrid reactor that combines a pulsed electrohydraulic discharge plasma with ultrasound application to increase the efficiency of wastewater treatments. The discharge and grounded electrodes are a needle-type electrode and a perforated plate, respectively. Ultrasound is directly applied to the plasma reactor through water by using ultrasonic oscillators. Hybridization of the pulsed high-voltage discharge with ultrasound generates a continuous streamer discharge by cavitation-induced bubbles. The phenol removal efficiency (energy yield) becomes higher than that corresponding to the sum of the efficiencies of the pulsed high-voltage discharge and ultrasonic applications.

用于去除有机化合物的超声波增强电动液压放电

摘要 我们使用混合反应器研究苯酚的分解，该反应器将脉冲电液放电等离子体与超声应用相结合，以提高废水处理的效率。放电电极和接地电极分别为针型电极和穿孔板。超声波通过使用超声波振荡器通过水直接施加到等离子体反应器。脉冲高压放电与超声波的混合通过空化诱导的气泡产生连续的流光放电。苯酚去除效率（能量产率）变得高于对应于脉冲高压放电和超声波应用的效率之和。
