| 摘 要： | 颗粒活性炭吸附有机废水中二异丙基苯等有机物后，采用Fenton试剂对活性炭进行氧化再生。研究H2O2与Fe2＋的摩尔配比及投加量、pH、温度、再生时间等因素对活性炭再生效果的影响。实验结果表明，Fenton体系中Fe2＋和H2O2的摩尔比为1：20，H2O2投加量为120mmol／L，pH为3，再生温度为25℃，再生时间为70min时，为最佳再生条件，再生率可达85．6％，且6次连续再生的平均效率仍能达到84．9％。Fenton试剂再生活性炭的方法表现出较高的经济和环境效益。

| Abstract: | The regeneration of granular activated carbon （GAC） which adsorbed diisopropyl benzene and other organic matters from organic wastewater using Fenton reagent was investigated at various H2O2 dosages, Fe2＋/H2O2 （mole ratio） , pH, temperatures and regeneration times. The optimal operating conditions for the re- generation of GAC were 120 mmol/L H2O2, Fe2＋/H2O2 of 1：20, pH of 3, temperature of 25℃ and regeneration time of 70 min. Under these conditions, the regeneration rate achieved its peak of 85.6% and average regenera- tion rate could still achieve 84.9% after six full cycles. Fenton reagent is an economic and environmental way for the regeneration of GAC. |
