Özet: The pollution parameters in the wastewater must be treated below the discharge criteria before the wastewater generated after industrial production is discharged to the receiving environment. Phenol and its derivatives are found in high concentrations in wastewater after industrial production. Wastewater containing this phenol and its derivatives have carcinogenic and teratogenic effects. Therefore, this type of wastewater should not be discharged to receiving environments without treatment. For this purpose, in this study, the removal of 2,4-dichlorophenol in a column filled with polyurethane upstream of activated sludge microorganisms activated with 2,4-dichlorophenol was investigated. Activated sludge microorganisms were immobilized on polyurethane sponge pieces and the purification of 2,4-dichlorophenol in a continuous system for 90 days in an upstream filled column was studied. According to the results, 83% COD and 86% phenol removal was achieved at the optimum 500 mg / L 2,4-dichlorophenol compensation.
