The target pollutant was real dyeing wastewater sampled from after primary treatment and bio-treatment respectively. The photocatalysis experimental method used suspended batch reactor. The manipulation parameters included the pH value (4, 7, 10) and dosages of photocatalyst (0.1 g/L, 0.2 g/L) affected the color residual, chemical oxygen demand (COD) and mineralization efficiency.

The results of the real dyeing wastewater showed that the best mineralization efficiency (32.0 %) and COD removal rate (50.8 %) on the condition of 0.2 g/L photocatalyst in pH 7, and the color residual rate of 0.2 g/L photocatalyst in pH 4, 7, 10 was individually 62.7 %, 56.0 % and 49.0 %. On the other hand, the results of the bio-treatment wastewater revealed the best mineralization efficiency (45.5%) and COD removal rate (53.0%) on the condition of adding 0.1 g/L dosage of photocatalyst in pH 7. In addition, the best color residual rate (63.0%) work on 0.2 g/L photocatalyst in pH 7. The conclusion of this study, it could enhance the mineralization efficiency of the dyeing wastewater in photocatalysis by TiO2 after bio-treatment. So the photocatalytic system work more efficiency behind the bio-treatment. 謝永旭 2012 學位論文 ; thesis 75 zh-TW |

碩士 === 國立中興大學 === 環境工程學系所 === 100 === In this study, preparation of titanium dioxide (TiO2) was synthesized by sol-gel method. The target pollutant was real dyeing wastewater sampled from after primary treatment and bio-treatment respectively.
The photocatalysis experimental method used suspended batch reactor. The manipulation parameters included the pH value (4, 7, 10) and dosages of photocatalyst (0.1 g/L, 0.2 g/L) affected the color residual, chemical oxygen demand (COD) and mineralization efficiency. Therefore, explore the feasibility of photocatalytic applied to real dyeing wastewater.
The results of the real dyeing wastewater showed that the best mineralization efficiency (32.0 %) and COD removal rate (50.8 %) on the condition of 0.2 g/L photocatalyst in pH 7, and the color residual rate of 0.2 g/L photocatalyst in pH 4, 7, 10 was individually 62.7 %, 56.0 % and 49.0 %.

The conclusion of this study, it could enhance the mineralization efficiency of the dyeing wastewater in photocatalysis by TiO2 after bio-treatment. So the photocatalytic system work more efficiency behind the bio-treatment.
