THE FULL-SCALE TREATMENT PLANT FOR DECOLOURISATION OF DYE WASTEWATER

The paper presents a short description of full-scale chemical treatment plant, based on the Fenton reagent, designed for decolourisation and purification of dye wastewater from production of matches. This treatment plant has been working since December 2000 in a chemical factory located in southern Poland. It is the first chemical plant in Poland, with Fenton reagent, intended for treatment of this type wastewater. It has been shown that the Fenton reagent process is a highly effective treatment technology for decolourisation and degradation of dye wastewater from production of matches. The Fenton reagent can achieve high removal efficiency for various parameters, such as COD, colour, and toxicity. After the Fenton oxidation, complete elimination of specific colour and toxicity (in relation to bacteria Vibrio Fischeri) is observed. This technology is fully professional, highly efficient, safe and flexible. The long-term experiences on a technical scale, suggest that Fenton reagent can be also applied successfully in other industries, which produce wastewater resistant to biodegradation.
