Treatment of Synthetic Petroleum Refinery Wastewater in Anoxic Reactors at Varied Feed Phenol
Abstract Present study was carried out using simulated refinery wastewater of varying concentrations of phenol in feed along with diesel, sulphide, ammonia–nitrogen (NH4 +–N) and nitrate–nitrogen (NO3 −–N). Four reactors were maintained in anoxic environment with heterogeneous microorganisms grown on sponge cubes. Hydraulic retention time was constant of one day in all reactors. Degradations of phenol, diesel and organic COD were inhibited with increase in feed phenol concentrations. Denitrification increased as more amount of NO3 −–N was consumed for phenol removal in anoxic environment. With increase in feed phenol, sulphide degradation was favoured and higher amount of feed sulphide was converted to elemental sulphur (S0). Batch kinetics studies revealed complete degradation of all pollutants in anoxic condition, and time required for complete removal increased with increase in feed phenol concentration.
