摘要
基于目前活性炭再生方法存在的问题,研究了介质阻挡放电等离子体方法再生活性炭.探讨了电气参数,如放电电压、放电时间以及电源频率等因素对吸附有五氯酚的废活性炭再生效果的影响.结果表明:放电电压和放电时间存在一个最佳值,太高或太低的放电电压和放电时间都不利于活性炭的再生;当电源频率从200 Hz增加时,随着电源频率的增加,再生效果降低.
There are still many problems in the regeneration method of activated carbon （AC）. In this paper, the dielectric barrier discharge （DBD） was used to investigated the regeneration of AC. The main effects of electric parameters, such as discharge voltage, discharge time and power supply frequency, on regeneration efficiency of exhausted carbon was carried through the adsorption of pentachlorophenol. The results indicated that the discharge voltage and time had an optimum values. Too high or low discharge voltage and time were bad for the regeneration of exhansted AC. The regeneration efficiency decreased when the power supply frequency increased from 200 Hz
