Abstract:

TNT wastewater has been treated by microwave radiation Fenton’s reagent. The effect factors， such as wastewater initial concentration， amount of H₂O₂，microwave irradiation time， microwave power and pH on TNT wastewater have been investigated. The results show that when the microwave power is 480 W， microwave irradiation time is 6 min，6% H₂O₂ dosage is 1.5 mL， FeSO₄dosage is 0.07 g and pH=4， the removal rate of COD of TNT wastewater is 84.5%. The contrast experiments among three treatment processes， including single microwave radiation，single Fenton’s reagent oxidation and microwave radiation Fenton’s reagent reveal that microwave radiation Fenton’s reagent has obvious supority.

摘要：

采用微波辐射Fenton试剂处理TNT废水，分别考察了TNT废水初始浓度、双氧水用量、微波辐射时间、微波功率和pH等因素对TNT废水处理效果的影响。结果表明，在微波功率为480 W、微波辐射时间为6 min、6%的双氧水用量为1.5 mL、FeSO₄质量为0.07 g和pH=4的条件下，TNT废水COD去除率达到84.5%。单独微波辐射、单独Fenton试剂氧化、微波辐射Fenton试剂3种不同方法的对比实验表明，微波辐射Fenton试剂有明显的优越性。
