Title Of Article :
APPLICATION OF SEVERAL ADVANCED OXIDATION PROCESSES FOR THE DESTRUCTION OF ORGANICS IN EFFLUENTS OF PTA PRODUCTION
Abstract :
In this study, the efficiency of several advanced oxidation processes such as ultrasonic oxidation, heterogeneous Fenton-like oxidation, ultrasound or UV assisted heterogeneous Fenton-like oxidation, heterogeneous sonophotoFenton oxidation and oxidation with ultrasound+UV light combination was tested for COD reduction in effluents of purified terephthalic acid (PTA) production. The highest COD removal was achieved as 18% when UV light assisted heterogeneous Fenton-like oxidation was applied to PTA manufacturing wastewater in the presence of 5 wt% iron containing TiO2 catalyst. This combined advanced oxidation process seems to be a promising one to enhance the COD removal when it is used after biological treatment.
