Özet:

 Wastewater treatment plants WWTPs are considered as one of the most important point sources for releasing antibiotics into the natural environment. In this study, the occurrence, fate, and removal of three antibiotics, ciprofloxacin CIP, sulfamethoxazole SMX, and azithromycin AZI, belong to quinolone, sulfonamide, and macrolide groups, respectively were investigated seasonally in a large-scale urban WWTP. While the occurrence concentrations of the investigated antibiotics in raw wastewater were found between about 0.26 and 0.73 μgL in the summer season, it was determined in the range of approximately 0.41 and 4.6 μgL in the winter season. Although the removal efficiencies obtained for antibiotics in the pre-treatment stage of the studied advanced biological WWTP were not very high, the most treated compound in the pre-treatment stage was determined as CIP up to 23.8. Total removal efficiencies of the investigated antibiotics in the WWTP varied mainly based on the biological treatment stage of the WWTP. At the same time, removal efficiencies of the antibiotics obtained in the biological treatment also changed considerably depending on the seasons. Among all the investigated antibiotic compounds, it was determined that AZI was the compound that was least affected by the seasons in terms of the total removal efficiency obtained in WWTP. According to the annual average total removal efficiencies, it was determined that SMX 25.7, CIP 71.3, and AZI 89.2 were treated poorly, moderately, and highly in WWTP, respectively. However, advanced biological WWTP was determined to be insufficient for the complete removal of total antibiotics.

 Atıksu arıtma tesisleri AATler, antibiyotiklerin doğal ortama geçişi için en önemli noktasal kaynaklardan biri olarak kabul edilmektedir. Bu çalışmada, sırasıyla kinolon, sülfonamid ve makrolid gruplarına ait üç antibiyotik bileşik siprofloksasin CIP, sülfametoksazol SMX ve azitromisinin AZI büyük ölçekli kentsel bir AATdeki oluşumu, akıbeti ve uzaklaştırılması mevsimsel olarak araştırılmıştır. İncelenen antibiyotiklerin ham atıksulardaki oluşum konsantrasyonları yaz mevsiminde yaklaşık 0,26 ile 0,73 μgL arasında bulunurken kış mevsiminde ise yaklaşık 0,41 ile 4,6 μgL aralığında belirlenmiştir. Çalışılan ileri biyolojik AATnin ön arıtma kademesinde antibiyotikler için elde edilen giderim verimleri çok yüksek olmamak ile birlikte ön arıtma kademesinde en fazla arıtılan bileşik CIP 23,8e kadar olarak belirlenmiştir. AATde araştırılan antibiyotiklerin toplam giderim verimleri esas olarak AATnin biyolojik arıtma kademesine bağlı olarak değişiklik göstermiştir. Aynı zamanda biyolojik arıtmada antibiyotikler için elde edilen giderim verimleri de mevsimlere bağlı olarak önemli ölçüde değişmiştir. İncelenen tüm antibiyotik bileşikler arasında AATde elde edilen toplam giderim verimi açısından mevsimlerden en az etkilenen bileşiğin AZI olduğu belirlenmiştir. Yıllık ortalama toplam giderim verimlerine göre AATde; SMX 25,7, CIP 71,3 ve AZInin 89,2 sırasıyla düşük, orta ve yüksek oranda arıtıldığı belirlenmiştir. Bununla birlikte, ileri biyolojik AATnin toplam antibiyotiklerin tamamen giderilmesi için yetersiz olduğu belirlenmiştir.
