Abstract
The purpose of this study was to determine the biodegradability of 2 4-dichlorophenol 2 4-DCP in an anaerobic reactor aerobic sequential reactor system. Target compound 2 4-DCP present in simulated wastewater at a concentration of 200 mg L-1 was treated sequentially in continuous mode by combined anaerobic hybrid reactor AHR and submerged aerobic fixed film SAFF reactor . Sodium acetate was used as co-substrate at 3 g L-1. Hydraulic retention time HRT was kept constant at 24 h. Almost complete mineralization of 2 4-DCP was achieved at 2 4 DCP loading rates from 0.005 g L-1 d·1 to 0.200 g L-1 d·1 and organic loading rates in AHR from 1.34 kg COD m-d.1 to 1.52 kg COD m-3 d-1. The COD removal efficiency of AHR varied from 50.6 to 70.45. The 2 4-DCP removal efficiency of AHR varied from 40.3 to 73 6. The COD removal efficiency of SAFF reactor varied from 85 to 96.9. The 2 4-DCP removal efficiency of SAFF reactor varied from 83.9 to 100. The overall COD removal efficiency by combined AHR and SAFF reactor was 92.9 to 98.8. The overall 2 4-DCP removal efficiency by combined AHR and SAFF reactor was 96 to 100.
