  • 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.

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.
