Özet:

 Classical activated sludge systems have been used for over a century in domestic wastewater treatment. However, in recent years, not only carbon removal but also nitrogen and phosphorus removal have become essential for preserving water resources. In this context, scientists are searching for effective and sustainable solutions. In this study, the integrated biological activated sludge IFAS process, which is created by integrating fixed biofilm into the classical activated sludge process, was applied by combining it with a sequential batch reactor SBR. The IFAS-SBR system was applied in the sequencing batch reactor with a 40 volume fill ratio of moving support material, utilizing anaerobic Anaerobic Oxanoxic Ox cycles, with a 36 hour hydraulic retention time HRT and an 11.8-day sludge retention time SRT. During the operational phases, average removal efficiencies of 92.7 for chemical oxygen demand COD, 79.5 for total nitrogen TN, and 59.3 for phosphate phosphorus PO4-P were achieved. Considering discharge criteria, the reactor achieved successful COD and TN removal, but fell short in terms of phosphorus removal. The IFAS-SBR reactor, has the potential to meet wastewater standards under optimized conditions.

 Klasik aktif çamur sistemleri, evsel atıksu arıtımında yüz yıldan uzun bir süredir kullanılmaktadır. Ancak son yıllarda su kaynaklarının korunması için sadece karbon giderimi değil, azot ve fosfor giderimi de gereklilik haline gelmiştir. Bu bağlamda bilim insanları, etkili ve sürdürülebilir çözümler arayışındadır. Bu çalışmada, klasik aktif çamur prosesine sabit biyofilm entegre edilerek oluşturulan entegre biyolojik aktif çamur EBAÇ prosesi, ardışık kesikli reaktör AKR ile birleştirerek uygulanmıştır. EBAÇ-AKR sistemi, ardışık kesikli reaktöre, 40 doluluk hacminde hareketli destek materyali ilave edilerek anaerobikAn  aerobikOx  anoksik Ox faz sırası, 36 saat hidrolik bekleme süresi HBS ve 11.8 gün çamur yaşı ÇY ile işletilerek uygulanmıştır. Çalışma aşamalarında ortalama kimyasal oksijen ihtiyacı KOI 92.7, toplam azot TN 79.5 ve fosfat fosforu PO4-P giderimi 59.3 olarak elde edilmiştir. Deşarj kriterleri dikkate alındığında reaktör KOI ve TN gideriminde başarılı olurken P gideriminde yetersiz kalmıştır. EBAÇ-AKR reaktörü optimize edilmiş şartlarla atıksu standartlarını sağlama potansiyeli bulunmaktadır.
