Özet
Bu çalışmada iplik boyama yapan bir tekstil endüstrisi boyama prosesinden alınan iki numuneye laboratuar koşullarında ozon oksidasyonu, persülfat (PS) oksidasyonu ve peroksimonosülfat (PMS) oksidasyonu yöntemleri uygulanarak TOK giderim verimi, renk giderim verimi ve BOİ5/TOK oranı incelenmiştir. Ozonlama işleminde 2 g/saat dozunda ozon verilerek 15, 30, 45, 60, 90, 120. dakikalarda örnekleme yapılmıştır. PS ve PMS oksidasyonunda sıcaklık 70o C’de sabit tutulup 30 mmolar oksidan ilavesi yapılarak 15, 30, 45, 60, 90, 120. dakikalarda örnekleme yapılmıştır. Ozonla oksidasyon sonucunda iki atıksu için TOK giderim verimi sırasıyla %14.7 ve %12.5; renk giderim verimi sırasıyla %85.2 ve %94.1; BOİ5/TOK oranı da sırasıyla 0.38 ve 0.047 olmuştur. PS oksidasyonu sonucunda, TOK giderim verimi sırasıyla %19 ve %9.9; renk giderim verimi sırasıyla %99.99 ve %95.1; BOİ5/TOK oranı da sırasıyla 0.48 ve 0.041 olmuştur. PMS oksidasyonu sonucunda, TOK giderim verimi sırasıyla %16.2 ve %6.7; renk giderim verimi sırasıyla %98.8 ve %88.2; BOİ5/TOK oranı da sırasıyla 0.41 ve 0.039 olmuştur.
In this study, TOC, color removal efficiencies and BOD5/TOC rates were investigated in dyeing processess wastewaters by using ozone, persulfate (PS) and peroxymonosulfate (PMS) oxidation in laboratory. In ozone oxidation, ozone was given 2 g/hour dose and samples were taken in 15, 30, 45, 60, 90 and 120 minutes. In PS and PMS oxidation, the temperature was kept constant at 70 0 C and samples was taken in 15, 30, 45, 60, 90 and 120 minutes by adding 30 mmolar oxidant. In ozonation process TOC removal efficiencies of two wastewaters were found as 14.7 % and 12.5 %, color removal efficiencies were found as 85.2%, 94.1%, BOD5/TOC rates were found as 0.38 and 0.047 respectively. In PS oxidation TOC removal efficiencies of two wastewaters were found as 19 % and 9.9 %, color removal efficiencies were found as 99.99 % and 95.1%, BOD5/TOC rates were found as 0.48 and 0.041 respectively. In PMS oxidation TOC removal efficiencies of two wastewaters were found as 16.2 % and 6.7 %, color removal efficiencies were found as 98.8 % and 88.2%, BOD5/TOC rates were found as 0.41 and 0.039 respectively.
