Özet
This experimental study was conducted to investigate the effect of coagulation-flocculation (CF), ozonation (O), coagulation-flocculation after ozonation (O/CF), ozonation after coagulation-flocculation (CF/O) and Fenton processes on the Tekirdağ Province Municipal Sanitary Landfill leachate treatment in the city of Tekirdağ. Also, the effects of Al2(SO4)3 and FeCl3 dosages on coagulation-flocculation process, oxidation time on ozonation process and H2O2 and FeSO4 dosages on Fenton process in the removal of chemical oxygen demand (COD) were studied. The following parameters were analyzed for characterization study: pH, conductivity, COD, dissolved COD, total suspended solids (TSS), NH4-N and alkalinity. The study shows that in CF, FeCl3 was effective for all three samples in terms of COD removal and the removal efficiencies for Sample 1, 2 and 3 were 40.5%, 46.8% and 55.2%, respectively. The amount of ozone applied in ozonation process was 1 g O3 per hour and after 120 minutes ozonation the COD removal efficiencies were insufficient and 14.5%, 24.4% and 31.8%, respectively. In all treatment methods the best removal efficiencies were obtained as 80.2%, 79.6% and 78.8%, respectively by Fenton process. The COD values for Samples 1, 2 and 3 after the Fenton process were found to be 509, 456 and 397 mg/L, respectively. It was also determined that the removal efficiencies of coagulation-flocculation process which applied after ozonation were 70.4%, 74.4% and 67.7%, respectively and close to the Fenton process. © 2021 Gheorghe Asachi Technical University of Iasi, Romania.
