Keywords: Textile industry dyeing wastewater, fenton, peroxy-electrocoagulation, color. The dark black colored sample containing dispersed dye mixture (Buffer Acid, Degapers Micro, Code: 3s001- Polyclear Sr, Sudkostik) in the content of PHPERS BLACK CT used in the research was taken directly from the dye tank without washing after textile industry dyeing process in Akyazı and removal efficiency of fenton and peroxyelectrocoagulation method researched. According to the data obtained from the experimental studies, Fenton oxidation process for the fenton oxidation method was 86.28% COD and color RES436 = 98.96%, RES525 = 99.36%, RES620 = 99.76% at optimum pH = 3; H2O2 dose was determined as 5g/L and color RES436 = 98.15%, RES525 = 98.8%, RES620 = 99.25% and 86.28% COD removal were performed. 3 g L Fe2+ ion concentration preferring color RES436 = 99.34%, RES525 = 99.60%, RES620 = 99.83% and 87.65% COD removal, time RES436 = 99.40%, RES525 = 99.63%, RES620 = 99.84%, RES436 = 99.51% and 87.79% COD at 120 min. In the peroxy-electrocoagulation method, optimum pH = 3, 82.16% COD and color RES436 = 98.96%, RES525 = 99.36%, RES620 = 99.75% removal, Hydrogen peroxide dose was determined to 5 g / L Color RES436 = 98.96%, RES525 = 99.36%, RES620 = 99.75% and 82.16% COD removal efficiency were obtained at .5g / LH 2 O 2. If the current density is higher than 0.08m A/cm2 preferable amperes yield value is very little and summer increases. current density 0.08 mA/cm2 at color RES436 = 99.51%, RES525 = 99.6%, RES620 = 99.78% and 86.55% COD value, duration 30 minutes at color RES436 = 99.28%, RES525 = 99.34%, RES620 = 99.54% and 84.9% COD removal efficiency values were found. In this study treatment of textile wastewater dyeing fabric in Akyazı by fenton and peroxi-electrocoagulation method was investigated. According to experimental results, the optimum conditions have been found as 3 g/L of ferrous ions concentration, 5 g/L of H2O2 concentration, pH 3 and 60 min. of reaction time for Fenton process. After 60 min time, (wavelenght of 436 nm, 525nm, 620 nm ) % 98,96, % 99,36, % 99,76 for RES respectively. The COD removal efficiency has been calculated as % 86,28. The optimum conditions have been found I=0,08A, 5 g/L H2O2 concentration, pH 3 and 90 min of reaction time for peroxi-electrocoagulation process. After 90 min time, (wavelenght of 436 nm, 525nm, 620 nm) % 99,61,% 99,76, % 99,83 for RES respectively. The COD removal efficiency has been calculated as % 89,44.
