摘要：
Treatment of textile wastewater by advanced oxidation processes (AOPs) based on zero-valent aluminium (ZVAl) were carried out in the present study. COD removal efficiencies of ZVAl/O-2, ZVAl/Fe3+/O-2, ZVAl/Fe3+/O-2/H2O2 and ZVAl/Fe3+/O-2/persulfate processes were monitored and optimized. Colour and ammoniacal nitrogen removal efficiencies of each process at the optimal operating conditions were compared. Pollutant removal efficiencies of AOPs were followed the order as: ZVAl/Fe3+/O-2/H2O2 > ZVAl/Fe3+/O-2/persulfate > ZVAl/Fe3+/O-2 > ZVAl/O2. Maximum COD, colour and ammoniacal nitrogen removal efficiencies of ZVAl-based AOPs were found as 97.9%, 94.4% and 58.3%, respectively at 1 g/L ZVAl, 0.5 g/L Fe3+, 6.7 g/L H2O2 and after 3 h of contact time. External addition of tert-butyl alcohol to the processes revealed that in-situ hydroxyl and sulfate radicals are the main oxidants responsible for the oxidation of pollutants. Overall, ZVAl-based AOPs are efficient for treating effluents generating from textile industry.
