摘　　要：以活性炭为吸附剂和吸波载体,对微波再生法和直接微波法去除水中的苯酚进行了对比试验研究。结果表明,在两种微波辐射方式下,活性炭都能有效去除水中的苯酚,其中微波再生法对活性炭的一次再生率可达96,多次再生率为50～70;活性炭直接微波法对苯酚的去除率较单独活性炭吸附提高了7～20,在苯酚浓度较低(462mg/L)时对其去除率最高达93。试验结果还表明,微波再生法的除污效能指标(P)值普遍高于直接微波法,且活性炭可重复利用,是一种更为经济有效的微波方法。Using activated carbon as adsorbent and microwave absorption cartier, a comparative test was done by methods of microwave regeneration and direct microwave to remove phenol from water. The results show that two methods of microwave radiation can both help activated carbon to remove phenol from water effectively. The single regeneration rate of activated carbon by microwave regeneration can reach 96%, and the repeated regeneration rate is 50% to 70%. The removal rate of phenol by direct microwave/activated carbon is increased by 7% to 20% compared with activated carbon adsorption alone, and the highest removal rate is 93% when the phenol concentration is 462 mg/L. The removal efficiency （P） of pollutants by microwave regeneration is generally better than that by direct microwave, and the activated carbon can be used repeatedly, so it is a more economic and effective method.
