چکیده مقاله:

An anaerobic hybrid reactor (UASB/Filter) used for petrochemical wastewater treatment at mesophilic condition. The seeded flocculent sludge from a UASB plant treating dairy wastewater, acclimatized to the petrochemical wastes in two-stage operation. After start up, under steady state conditions, experiments were conducted at OLRs of between 0.5 and 24 kg TCOD m-3d-1, hydraulic retention times (HRT) of 4-48 h and up flow velocities 0.021-0.25 mh-1. Removal efficiencies in the range of 42-86% were achieved at feed TCOD concentrations of 1000-4000 mg L-1. The results of reactor performance at different operational conditions and its relations presented and discussed in this paper. Then, the obtained date used for determination of kinetic models. The results showed that Second-order model and a modified Stover-Kin cannon model were the most appropriate models for this reactor. Finally the biogas production data used for determination of biogas production kinetics.
