영문 초록

Dyehouse wastewater has many environmental problems with their high pollutant concentration and color. Wastewater of Small dyehouses in Seoul were sampled and analyzed the physicochemical characteristics and investigated the influence of various experimental parameters of Fenton oxidation, such as pH, feeding rate of H₂O₂ and FeSO₄, reaction time and temperature and measured the COD removal efficiency by Fenton oxidation. In the analysis of raw dyehouse wastewater, high correlationship was shown between the APHA apparent color and visible wavelength peak absorbance and between COD cone. and UV peak absorbance. Hydrogen peroxide was very important in the Fenton oxidation and feasible amount of hydrogen peroxide was 0.1 ~ 0.3 ml/l to the wastewater of low COD cone. and 0.3 ~ 0.5 ml/I to the high COD cone. Efficiency of COD removal by Fenton oxidation was highest in pH 3.5. The efficiency was not low in pH 7 and the possibility of oxidation in neutral pH was shown. At the high COD wastewater, the feasible amount of oxidants were determined to 0.5~1 ml/I H₂O₂, 1200 ml/l FeSO₄·7H₂O, and at the low COD wastewater 0.5 ml/l H₂O₂, 800 ml/l FeSO₄·7H₂O. As the remained COD cone. was high after Fenton Oxidation of the wastewater with high raw COD, additional treatment should be considered to emit treated water.
