摘　　要：针对实验室废水,采用活性碳联合Fenton试剂氧化处理,探讨主要因素对COD处理效果的影响。实验结果表明,活性碳在添加量为0.45 g/mL,反应30 min后对废水中COD的去除率达61.32%;Fenton试剂在H2O2添加量为0.07 mg/mL,FeSO4·7H2O的添加量为0.02 g/mL的条件下反应60 min后,对废水中COD的去除率达到59.88%;将活性碳吸附和Fenton试剂联合作用后,活性碳添加量减少了0.05 g/mL,FeSO4·7H2O添加量减少了0.005 g/mL,去除率可达89.23%,显著提高实验室废水中COD的去除率。Lab waster water was disposed by combining activated carbon and Fenton reagent oxida- tion. The effect of the combined method on disposing COD was analysed. When the addition of the activated carbon reaches 0.45 g/mL, the disposing rate of COD reaches 61.32% after 30 minutes of reaction. When the addition of Fenton reagent in H2 O2 amounts to 0.07 mg/mL and the amount of FeSO4· 7H2Oreaches 0.02 g/mL, the disposing rate of COD is 59.88% after 60 minutes of reac- tion. The amount of active carbon and FeSO4 · 7H2O can be reduced by 0. 05 g/mL and0. 005 g/mL respectively through combining activated carbon and Fenton reagent, while the dis- posing rate of COD increases up to 89.23%. The results indicate that the combined method can greatly increase the COD disposing rate of the lab waste water
