Abstract

Phenol is toxic, carcinogenic, and carcinogenic, and a teratogenic. Therefore, remove phenol from oil refinery wastewater before it is discharged. The main objective of the present investigation was to evaluate the effect of temperature and phenol concentration on anaerobic waste stabilization pond (WSP) efficiency for the treatment of oil refinery wastewater. In this study, phenol concentrations of 100, 200, 300, and 400 mg/L and a temperature range of 10°C–13°C were surveyed. Parameters such as phenol, COD, and BOD pH were investigated. Out of these parameters, phenol concentration and temperature were found to affect WSP efficiency. The efficiency of the anaerobic WSP increased when the phenol concentration decreased. Results also showed that the efficiency of the anaerobic WSP in low temperatures decreased. Hence, the efficiency of anaerobic ponds for the the removal of phenol from oil refinery wastewater is improved when temperatures are high and phenol concentrations are low.
