Abstract
Düzenli depolama sahalarındaki sızıntı suları, yüksek kirliliğe sahip karmaşık atık sulardır ve biyolojik olarak parçalanabilirlikleri de zordur. Yüksek konsantrasyonlarda kirletici madde içeren deponi sahası sızıntı suyuna ön arıtma yapılmalıdır. Bu nedenle, amonyum sıyırma işlemi, özellikle sızıntı suyunun amonyum giderimi için etkili bir yöntemdir. Amonyum sıyırma işlemi ile amonyum ve organik maddelerin giderimi artar. Bu çalışmada, amonyum sıyırma işleminin ham sızıntı sularından amonyum (NH4+) ve kimyasal oksijen ihtiyacı (KOI) giderilmesinin uygulanabilirliği araştırıldı. Amonyum sıyırma kulesi adı verilen yeni bir sistem tasarlanmıştır. Bu çalışma sırasında amonyum sıyırma işlemi, sıcaklık (30-40-60oC), havalandırma oranı (HH, HL, LL m3air / dak) ve hidrolik bekletme süreleri (6-12-24-48 saat) olarak gerçekleştirildi. Sistem performansı amonyum ve KOI parametreleri ile değerlendirildi. Amonyum sıyırma işleminin optimum koşulları 60°C sıcaklık, HH (1m3hava/ dakika) havalandırma hızı ve (48 saat) hidrolik bekletme süresi belirlenmiştir. Karşılık gelen amonyum ve KOIgiderim verimleri sırasıyla yaklaşık% 88 ve % 79’dur. Bu çalışmanın sonuçları, bir amonyum sıyırma işleminin kullanılmasının, ham depolama sahası sızıntı sularından amonyum ve KOI konsantrasyonunu gidermek için etkili bir yöntem olduğunu göstermektedir.

Abstract
Landfill leachates are complex wastewater which has high pollution and their biological degradability is also difficult. Landfill leachate with high concentrations of contaminants must be pretreated. For this reason, the ammonium stripping process is an effective method for ammonium removal, especially for landfill leachate. With the ammonium stripping process, the ammonium and organic matter removal increases. This study aimed to investigate the applicability of the ammonium stripping process as remove ammonium (NH4+) and chemical oxygen demand (COD) from raw leachate. A new system has been designed which is called ammonium stripping tower. During this study, the ammonium stripping process was operated temperature (30-40-60oC), aeration rate (HH, HL, LL m3air/min), and hydraulic retention times (6-12-24-48 h). System performance was evaluated by ammonium, and COD parameters. The optimum conditions of the ammonium stripping process were determined at 600C temperature, HH(1m3air/min aeration rate), and hydraulic retention time (48h). The corresponding ammonium and COD removal efficiencies were about 88% and 79% respectively. The results of this study suggest that the use of an ammonium stripping process is an effective way to remove ammonium and COD concentration from raw landfill leachate.
