Submerged arc plasma technology was assessed for the removal of phenols from wastewater. The OH radicals generated from the boundary between the plasma and waste solution were considered as a significant factor on the degradation reaction. In this study, the effects of highly energetic electrons released from the submerged arc plasma were mainly studied. The highly energetic electrons directly broke the strong chemical bond and locally increased the reaction temperatures in solution. The effects of the submerged-arc plasma on the decomposition of phenol are discussed in terms of the input energy and initial concentration. The single use of submerged arc plasma easily decomposed the phenol but did not increase the mineralization efficiency. Therefore, the submerged arc plasma, coupled with the ozone injection, was investigated. The submerged arc plasma combined with ozone injection had a synergic effect, which led to significant improvements in mineralization with only a small increase in input energy. The decomposition mechanism of phenol by the submerged arc plasma with the ozone was analyzed.

评估了埋弧等离子体技术用于去除废水中的苯酚。从血浆和废液之间的边界产生的OH自由基被认为是降解反应的重要因素。在这项研究中，主要研究了从埋弧等离子体释放的高能电子的影响。高能电子直接破坏了强化学键，并局部提高了溶液中的反应温度。从输入能量和初始浓度的角度讨论了埋弧等离子体对苯酚分解的影响。单独使用浸没电弧等离子体可轻松分解苯酚，但不会增加矿化效率。因此，研究了埋弧电弧等离子体和臭氧注入技术。埋弧等离子与臭氧注入相结合具有协同作用，从而导致矿化作用得到显着改善，而输入能量仅有少量增加。分析了埋弧等离子体与臭氧对苯酚的分解机理。
