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35、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 750mg/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.

Abstract: 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, FeSO4·7H2O=5 g/L. Under these conditions, COD Cr 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 COD Cr and Cu(II) decreased evidently both in single microwave and single Fenton oxidation.
