Okside edici çeşitli kimyasalların kullanımıyla gerçekleştirilen çamur dezentegrasyonu, anaerobik çamur çürütme performansını ve biyogaz verimini önemli derecede arttıran bir çamur ön arıtım yöntemi olarak kabul edilmektedir. Bu çalışmada farklı dozlarda hidrojen peroksit (HP) ve peroksimonosülfat (PMS) kimyasalları kullanılarak, konserve gıda fabrikası orijinli bir atık aktif çamur örneği dezentegre edilmiştir. Ayrıca ultrasonik yöntemle gerçekleştirilen aktivasyon işleminin (40 kHz, 30 dak.) etkisi, dezentegrasyon verimliliği açısından irdelenmiştir. Uygulanan yöntemlerin etkinliğinin değerlendirilmesi, çamurdaki çözünmüş kimyasal oksijen ihtiyacı (ÇKOİ) parametresindeki değişimler üzerinden yapılmıştır. Çalışma sonuçları, sadece HP ve PMS ile yapılan dezentegrason yöntemlerinde ulaşılan maksimum ÇKOİ değerlerinin istatistiksel olarak benzer olduğunu göstermiştir. Ultrasonik yöntemle aktivasyonun gerek PMS gerekse HP ile gerçekleştirilen çamur dezentegrasyon verimliliğini belirgin şekilde arttırdığı sonucuna ulaşılmıştır. Dezentegre edilmemiş çamurda 0,05 olarak belirlenen ÇKOİ/TKOİ (Çözünmüş Kimyasal Oksijen İhtiyacı/Toplam Kimyasal Oksijen İhtiyacı) değeri ultrasonik olarak aktive edilmiş kimyasal ilavesiyle 0,33-0,36 seviyelerine çıkmıştır. Yürütülen çalışma kapsamında ultrasonik olarak aktive edilmiş HP’nin 44 mM dozunda uygulanmasıyla en yüksek çamur dezentegrasyon verimliliğine ulaşıldığı tespit edilmiştir.

Sludge disintegration using various oxidizing chemicals is accepted as a sludge pretreatment method that significantly increases anaerobic sludge digestion performance and biogas yield. In this study, waste-activated sludge from a canned food factory was disintegrated using different doses of hydrogen peroxide (HP) and peroxymonosulfate (PMS) chemicals. In addition, the ultrasonic activation process (40 kHz, 30 min.) has been examined with respect to sludge disintegration efficiency. The evaluation of the effectiveness of the applied methods was made via the changes in the dissolved chemical oxygen demand (SCOD) parameter in the sludge. The results of the study showed that the maximum SCOD values achieved by HP and PMS disintegration were statistically similar. It has been concluded that the activation by the ultrasonic method significantly increased the efficiency of sludge disintegration performed with both PMS and HP. The value of SCOD/TCOD (Dissolved Chemical Oxygen Demand/Total Chemical Oxygen Demand) determined as 0.05 in the non-disintegrated sludge increased to 0.33-0.36 levels with the addition of ultrasonically activated chemicals. It has been determined that the highest sludge disintegration efficiency has been achieved with the application of ultrasonically activated HP at a dose of 44 mM.
