| 摘 要： | 为研究水处理活性炭的再生，利用超声波处理技术，以甲基橙为有机化合物模型，进行吸附饱和木质活性炭的超声处理再生实验。结果表明，Fe^2＋、Cu^2＋的加入明显提高了超声反应的脱色率。在pH值为1．0，温度为30℃，声能密度为180W／L，Fe^2＋和Cu^2＋的投加量为0．6g／L的条件下，超声反应30min后，脱色率都可达到95．5％。

| Abstract: | By using Methyl Orange as model compound, the regeneration of saturated adsorption wood -based activated carbons were investigated by means of ultrasonic treatment technique for the regeneration of water treated activated carbon. The results show that the rate of decolorization of the dyes greatly improved in the presence of Fe^2＋ ,Cu^2＋. Under the conditions of pH 1. 0, reaction temperature 30℃, sound intensity 180 W/L and Fe^2＋ and Cu^2＋ dosage 0. 6 g/L, the decolorization percentage reaches up to 95.5 %, after 30 minutes of ultrasonic treatment. |
