DETERMİNATION OF ODOR LEVELS IN WASTEWATER TREATMENT PLANTS BY OLFACTOMETRIC METHOD

Öz

Wastewater treatment plants are known as an odor source due to their activities and they cause complaints due to the fact that long term exposure to high concentrations of odors affects human behaviors and environment. The aim of this study is to detect the odor concentrations in the units of the facility. Thus, odor measurements were taken at 11 units of facility in three seasons. The rates of odor formation were, in order, found as sludge dewatering (39%), sludge thickening (9%), anaerobic tank (9%), primary sedimentation (8%), final sedimentation (8%), fine screen (7%), setrant (7%) and inlet-coarse screen (6%) units. Besides, the efficiencies of odor removal processes were found as 84.9% (Ozone) 28.2% (UV). With an effective odor control system, it has been found that the emissions are reduced below the legal limits. The results showed that odor control process is satisfactorily efficient

OLFAKTOMETRİK YÖNTEM İLE ATIKSU ARITMA TESİSİ ÜNİTELERİNDE KOKU DÜZEYLERİNİN BELİRLENMESİ

Öz

Atıksu arıtma tesisleri faaliyetleri gereği koku kaynağı olarak bilinir ve genellikle şikayete konu olur. Çünkü koku uzun dönemde ve yüksek yoğunlukta insan davranışlarını ve çevreyi olumsuz etkiler. Bu çalışmanın amacı tesisin ünitelerinde koku konsantrasyonlarının belirlenmesidir. Bu nedenle 11 ayrı ünitede 3 farklı dönemde olfaktometrik yöntem ile koku ölçümleri yapılmıştır. Tesiste en yüksek koku oluşumu sırasıyla çamur kurutma (%39), çamur yoğunlaştırma (%9), anaerobik havuz (%9), ön çöktürme (%8), son çöktürme (%8), ince ızgara (%7), kum tutma (%7), setrant (%7) ve giriş-kaba ızgara (%6) ünitelerinde tespit edilmiştir. Ayrıca koku önleme sisteminin verimi (ozon) %84,9, (UV) %28,2 tespit edilmiştir. Etkili bir koku kontrol sistemi ile atmosfere salınan emisyon değerlerinin yönetmelikte belirtilen idari yaptırım limitinin altına indirildiği görülmüştür. Bu sonuçlar tesiste etkili bir koku kontrol prosesinin gerçekleştiğini göstermektedir
