| 摘 要： | 采用微波强化Fenton氧化处理系统,研究H2O2浓度、Fe2+浓度、初始pH、微波辐射时间和微波辐射功率对沼液中喹乙醇、土霉素、四环素及金霉素降解效果的影响.结果发现,采用微波强化Fenton氧化降解沼液中抗生素与激素的最优条件是:H2O2浓度为40 mg/L、Fe2+浓度为12 mg/L、初始pH为4、微波辐射时间为2 min、微波辐射功率为中火(445W),沼液中喹乙醇、土霉素、四环素、金霉素和COD的去除率分别达到67％、93％、91％、88％和46％.在水浴条件下,与单独微波辐射和单独Fenton相比,微波强化Fenton氧化有明显的优越性. |

| Abstract: | An experimental system of microwave-assisted Fenton oxidation was designed to degrade olaquindox,oxytetracycline,tetracycline and chlortracycline in biogas slurry. The influences of H2O2 mass concentration,Fe2+ mass concentration,initial pH,microwave irradiation time and power on degradation efficiency were investigated. The optimal conditions were determined as follows:the H2O2 dosage of 40 mg/L,the Fe2+ dosage of 12 mg/L,initial pH of 4,microwave reaction of 2 min and power of 445 W. Under the optimum conditions,the removal rate was 67% for olaquindox,93% for oxytetracycline,91% for tetracycline,88% for chlortracycline and 46% for COD. It is known from the contrast experiments that microwave-assisted Fenton oxidation has obvious supority. |
