摘　　要：以络合铜生产废水为研究对象,考察了H2O2投加量、FeSO4投加量、pH值、微波辐射时间、微波辐射功率等因素对微波辐射Fenton氧化法去除污染物效果的影响.分析了最优条件下单独微波、单独Fenton以及两者联用对CODCr和Cu2+的去除作用,初步探索了各影响因子的作用效果和综合反应机理.结果表明,通过单因素实验优化微波辐射Fenton氧化处理络合铜生产废水的最佳工艺条件为:30%H2O2用量为130 mL/L、FeSO4.7H2O用量为5 g/L、pH值为3.5、微波功率680 W、微波辐射时间10 min.在此条件下,微波结合Fenton氧化使CODCr和Cu2+分别由14 750 mg/L、968 mg/L下降到1 327 mg/L、55 mg/L,单独微波下降到11 563 mg/L、681 mg/L,单独Fenton氧化下降到2 537 mg/L、99 mg/L.The effects of H2O2 mass concentration,Fe2＋ mass concentration,pH value,microwave power and irradiation duration on pollutant removal were investigated during microwave-assisted Fenton oxidation.Chelated copper wastewater was treated by single microwave,single Fenton oxidation and microwave-assisted Fenton oxidation under the most favorable conditions.The mechanisms of microwave-enhanced Fenton oxidation were analyzed.The optimal operating conditions during microwave-Fenton process are as follows：microwave power=680 W,irradiation time=10 min,dosage of Fenton was H2O2（30%）=130 mL/L,FeSO4·7H2O=5 g/L.Under these conditions,CODCr decreases from 14 750 mg/L to 1 327 mg/L,and Cu2＋ decreases from 968 mg/L to 55 mg/L.Compared with those by means of the microwave-oxidation process,the removal rate of CODCr and Cu（II） decreased evidently both in single microwave and single Fenton oxidation.
