摘　　要：在废水中进行直接高压脉冲电晕放电产生的等离子体可以有效地降解其中的有机物。考察了多种因素对高压脉冲电晕放电等离子体降解含酚废水效果的影响。减小放电电极的直径、提高废水的pH、光催化剂以及过氧化氢的存在等均可提高含酚废水的降解率。对质量浓度为100mg/L的对氯苯酚废水而言,高压脉冲放电降解与过氧化氢降解的协同效应可达17.81%。The degradation of organic compounds in wastewater with pulsed high-voltage corona discharge was very effective. The effects of some factors on degradation of phenol in wastewater with pulsed high-voltage corona discharge plasma were studied. The degradation efficiency could be raised by increasing the pH value of the wastewater and/or the diameter of the discharge electrode and/or adding the photo-catalyst and/or hydrogen peroxide into the wastewater. For the wastewater containing 100mg/L of pchlorophenol, the synergistic effect of the pulsed high-voltage discharge plasma degradation and the hydrogen peroxide degradation reached 17.81%.
