  • 摘要: 研究了1%和10% 2种浓度正丙醇废水在光催化氧化-Fenton组合工艺条件下的降解情况,分别考察了H2O2加药方式及剂量、Fe2+浓度、TiO2浓度,以及废水的初始浓度对反应的影响,得到了优化工艺参数。结果显示,在23 W的低压汞灯照射下,当Fe2+离子浓度为0.44 g/L,TiO2为0.4 g/L,H2O2分6次等幅递增投加,增幅为均值的10%,投加总量至28.6 g/L时,反应6 h后,组合工艺可将1%浓度正丙醇废水的COD从17 200 mg/L降低至2 000 mg/L。H2O2总用量为136.5 g/L,其他条件及加药方式不变条件下,废水浓度提高至10%,紫外光能量利用率明显提高,反应15 h后,可将COD从172 000 mg/L降至1 000 mg/L以下,降解速率随浓度降低而下降。
    Abstract: The degradation procedure of 1% and 10% 1-propanol wastewater by combined UV photocatalysis /Fenton process was investigated under different conditions. In the study, the addition manner & dosage of H2O2, the dosage of Fe2+ ion & catalyst TiO2, and the initial concentration of 1-propanol were tested for optimizing the operation parameters. It is found that the COD of 1% 1-propanol wastewater decreased from 17 200 mg/L to 2 000 mg/L by the combined process under the conditions: the irradiation of 23 W low-pressure UV mercury lamp, t=6 h, [Fe2+] =0.44 g/L , [TiO2]=0.4 g/L, and [H2O2]=28.6 g/L, which was put in 1 time per hour fractionally by a dose of gradual increasing, of that the range was 10% of the average value. Moreover, under the conditions: [H2O2]=136.5 g/L, t=15 h, and the other condition was kept, the COD of 10% 1-propanol wastewater decreased from 172 000 mg/L to 1 000 mg/L, whose decomposing rate came down as the COD decreased gradually. Compared to the reaction in the wastewater of low concentration, the efficiency of the UV was higher.
