| 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110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%. |
| 关 键 词： | 环境工程 UV-Fenton法 偏二甲肼(UDMH)废水 COD去除率 |

| Abstract: | 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 rati... |
