Kök Yüzdürme Yöntemi ile yüzeysel su kalitesinin iyileştirilmesinde Japon şemsiyesi ve Vetiverin fitoremediasyon kapasitesi

Abstract

Surface water is polluted due to many reasons, mainly wastewater and irrigation discharges, and loses their value for potential uses. In this study, phytoremediation was applied to improve the surface water, provided from a branch of the Gediz River, which supplies the fresh water of Izmir Bird Paradise, but not qualified as a quality source in terms of ecosystem. For this purpose, the removal efficiency for total phosphorus (TP), total nitrogen (TN) and total organic carbon (TOC) of Cyperus Alternifolius L. (umbrella palm) and Vetiveria zizanioides (L.) Nash (vetiver) were tested in the tanks, which were set with the floating treatment wetland (FTW) with a control group.TP, TN and TOC were measured in water on the 1st, 3rd, 7th and 14th days, macro and micronutrients were measured in the plants at the beginning and at the end of the study. According to the results, TP removal was 92%, 82%, 45%, TN removal was 62%, 52%, 24% and TOC removal was 79%, 66%, 13% in umbrella palm, vetiver and control tanks, respectively. The translocation factors (TF) that were expected >1 in plants were determined as Cd (1.55), Pb (1.27), B (1.19) and Cr (1.11) in vetiver, and in umbrella palm B (1.33) and Pb (1.14). Considering the increase in biomass, it can be said that the umbrella palm will remove metal at a higher rate. Overall, this study demonstrates that with the usage of umbrella palm and vetiver, FTW has the potential to be used as a green treatment method.
