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。An experimental system of microwave-assisted Fenton oxidation was designed to degrade olaquin- dox, 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 re- moval 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.
