| 中文摘要 |
| 采用Fenton法对竹制品废水生化出水的脱色和有机物去除进行了研究. 在综合考虑经济性和去除效果的基础上,起始COD质量浓度为430 mg·L-1、色度为1500倍的废水,在反应条件:t=30℃,pH为3.5,ρ(H2 O2)=1665 mg·L-1,c(Fe2+)/c(H2 O2)=0.072,反应时间3 h的情况下,Fenton氧化处理后,COD和色度的去除率分别高达87.5%和94.4%. 研究发现,色度的去除率要优于有机物(以COD计)的去除率,且受外界因素影响小. GC-MS分析结果表明:经过Fenton处理后,废水中的发色团和助色团基本上完全被去除. 中间产物主要是脂类衍生物,副产品有1-碘十三烷和正辛基醚等. |
| 英文摘要 |
| The decolorization and organic matter reduction of bamboo wastewater using Fenton oxidation was studied. Considering the cost and the removal efficiency, the optimal conditions were t=30℃,pH=3.5, ρ(H2 O2)=1665 mg·L-1, c(Fe2+)/c(H2 O2)=0.072 and reaction time 3 h, with an initial COD and color concentration of wastewater of 430 mg·L-1 and 1500 times, under these conditions, the removal efficiency of COD and color could achieve 87.5% and 94.4%, respectively. It was found that the color reduction was higher than that of organics, and less affected by operation factors. The GC-MS analysis revealed that the chromophoric groups and auxochromic groups were greatly removed after Fenton treatment. The intermediates were mainly ester derivatives, and the by-products included 1-iodo-tridecane and 1,1'-oxybisoctane. |
