Abstract:

为了说明脉冲放电等离子体对吸附有机物饱和活性炭的再生作用,以酸性橙II(AO7)为目标物,建立了吸附AO7饱和活性炭的气液混合的脉冲放电等离子体再生体系,考察了该再生体系中的关键因素,包括水溶液电导率、载气流速、活性炭量及再生时间对活性炭再生效果的影响规律。研究结果表明一定的放电操作参数下,在实验所考察的参数变化范围内,增加水溶液电导率,减少活性炭投加量,活性炭的再生效率随之提高;较高的水溶液电导率(1000μS/cm)和较低的活性炭添加量(1g)有利于活性炭再生;适宜的载气流速(2L/min)和放电作用时间(60min)下的活性炭再生效率较高;相应操作条件下的活性炭在20.4kV脉冲峰值电压和50Hz脉冲频率的等离子体作用体系中的再生效率可达71.6%。
