Abstract

A hybrid wastewater treatment method was used to improve the quality of the treated wastewater for possible reuses. Real textile wastewater was subjected to electrocoagulation and Fenton like oxidation sequentially. In the Fenton like oxidation process the performances of BiFeO3/RHAC and BiNiO3/RHAC (RHAC: Rice husk based activated carbon) catalysts were compared. BiNiO3/RHAC was determined to be more effective in total organic carbon removal. A parametric study was carried out in the presence of the selected BiNiO3/RHAC catalyst to investigate the effect of the catalyst loading, pH and the oxidant dosage on total organic carbon removal. The most suitable reaction conditions were determined as 1.5 g/L of catalyst loading, pH 7, and 2 mM initial hydrogen peroxide concentration. 17% and 15.7% total organic removal efficiencies were achieved in electrocoagulation and Fenton like oxidation processes, respectively, whereas the cumulative removal efficiency was 32.7%.

Özet

Arıtılan atıksuyun kalitesini olası bir yeniden kullanım için iyileştirmek amacıyla bir hibrit atıksu arıtım yöntemi kullanılmıştır. Gerçek tekstil atıksuyu sırasıyla elektrokoagülasyon ve Fenton benzeri oksidasyonuna tabi tutulmuştur. Fenton benzeri oksidasyonu prosesinde BiFeO3/RHAC ve BiNiO3/RHAC (RHAC: Pirinç kabuğundan elde edilen aktif karbon) katalizörlerin performansları karşılaştırılmıştır. BiNiO3/RHAC'nin toplam organik karbon gideriminde daha etkili olduğu belirlenmiştir. Katalizör yüklemesin, pH ve oksidan dozajının toplam organik karbon giderimi üzerine etkisini araştırmak için seçilen BiNiO3/RHAC katalizör varlığında parametrik çalışma gerçekleştirilmiştir. En uygun reaksiyon koşulları 1,5 g/L katalizör yüklemesi, pH 7 ve 2 mM başlangıç hidrojen peroksit konsantrasyonu olarak belirlenmiştir. Elektrokoagülasyon ve Fenton benzeri oksidasyonu proseslerinde sırasıyla %17 ve %15,7 toplam organik giderim verimleri elde edilirken kümülatif giderim verimliliği %32,7’dir.
