中文摘要:
      利用UV-Fenton方法处理偏二甲肼(UDMH)废水,以废水中UDMH和化学需氧量(COD)的去除率为检测指标,通过正交实验确定了反应的主要影响因素以及最佳工艺组合,并比较研究了五种反应体系的降解情况,初步探讨了中间产物的变化规律。实验结果表明:常温下,H2O2为1.5 Qth(theoretical quantity),pH值在3.5左右,Fe2+与H2O2的摩尔比为1:10时,经过45 min的UV-Fenton氧化降解,UDMH废水(400 mg/L)中UDMH去除率可达到99%以上,COD去除率可达到95.8%。

英文摘要:
      UV-Fenton process was applied to oxidize the unsymmetrialdimethy hydrazine(UDMH) wastewater. The optimal manufacturing process and the primary factors contribute to the UV-Fenton oxidation were determined by orthogonal experiments with removal efficiencies of the UDMH and COD in wastewater as two main monitor index,and the removal efficiencies of UDMH wastewater of five kinds of reaction systems were compared. Results show that when initial H2O2 is 1.5 times of the theoretical quantity(1.5 Qth),the molar ratio of Fe2+ to H2O2 is 1:10,pH value is 3.5,room temperature is 25 ℃,and the reaction time is 45 min,the removal effciency of UDMH and COD is over 99% and 95.8% respectively. The change curves of degradation intermediate products CN- and HCHO and the UV-visible spectroelectrochemistry spectra of UDMH wastewater degradation processes were studied. Results show that UV-Fenton process is efficient in UDMH wastewater treatment.
