TREATMENT OF DYEING WASTEWATER BY APPLYING PHOTO-FENTON OXIDATION TECHNOLOGY
Abstract
Treatment of textile wastewater was carried out at room temperature in a batch reactor by using the Photo-Fenton oxidation process. The reactor was designed with 5cm dia. and 61 cm height with inlet and outlet openings. The effects of initial pH of the solution (pH = 1-7), ferrous ion concentration (2-6 g) and UV power (60 W) on chemical oxygen demand (COD), biological oxygen demand (BOD) and colour removal were examined. The results showed that this process was enhanced at the acidic pH range. The optimum condition was found to be at pH = 3, 5.5 g Fe2+×l-1, 5-10 minutes operating time, 60 W UV power and 20 ml H2O2×l-1. At this condition, approximately COD (74.19%) & BOD (72.55% and colour were removed respectively. During the treatment process, a small amount of sludge (5.8×10 -5 kg×kg COD-1) was generated.
