摘　　要：采用微波强化Fenton工艺处理了偏二甲肼废水,考察了微波功率、H2O2投加量、pH值、Fe2+与H2O2摩尔比等因素对废水处理效果的影响,通过正交实验确定了该工艺的最佳条件。结果表明,在微波功率280 W,H2O2(68.5 g·L-1)投加量4.0 mL、水样pH=4.0、Fe2+与H2O2摩尔比1:16、反应时间8.0 min的条件下,偏二甲肼废水COD去除率可达98.4%。The unsymmetric dimethyl hydrazine（UDMH）wastewater was degraded by the microwave（MW）enhanced Fenton, and the effect factors,such as MW power,dosage of H2 O2 ,pH,Fe2 ＋H2 O2 molar ratio on wastewater treatment were studied. The best degradation conditions were determined by the orthogonal experiment. Results show that,the chemical oxygen demand （COD）removal rate could be 98.4% on condition that MW power is 280 W,H2O2（68.5 g·L -1）dosage 4.0 mL,pH 4.0, Fe2 ＋H2 O2 molar ratio 116 and reaction time 8. 0 min.
