中文摘要：
为了研究超重力技术对电化学反应过程中气泡的影响，分别对超重力环境下、重力环境下以及重力搅拌环境下，电化学法处理含酚废水过程中的气泡行为，如：电极表面气泡富集行为、废水中气泡分散行为、装置端盖上气泡聚集行为以及气泡溢出行为进行研究。结果表明：在重力环境下和重力搅拌环境下，电化学反应过程中产生的气泡主要附着于电极表面以及分散于电解液中，这会造成电化学反应效率下降和过程能耗增加。而在超重力环境下，电化学反应过程中产生的气泡可快速脱离电极表面以及从电解液中溢出。说明超重力技术可突破传统搅拌的传质极限，消除电化学反应过程中气泡对其过程的影响，从而提高电化学反应效率和降低过程能耗，这对电化学技术的工业化应用进程可起到推动作用。
英文摘要：
In order to research the influence of high gravity technology on the bubbles in the process of electrochemical reaction, the bubbles behaviors in the process of electrochemical treatment of phenol wastewater respectively under high gravity, normal gravity and stirring environment were studied. The bubbles behaviors included the bubbles gathered on the electrode surface, gathered on the reactor cover, scattered in the wastewater and the bubbles overflowed from the wastewater. The result shows that the bubbles mainly gather on the electrode surface and scatter in the wastewater under the normal gravity and stirring environment, but detach from the electrode surface and wastewater under the high gravity environment. It indicates that the high gravity technology can push the mass transfer limits in stirring and eliminate the bubbles influences on the electrochemical reaction, thus improving the reaction efficiency and reducing the energy consumption. High gravity technology can effectively advance the industrialization process of electrochemical technology.
