摘要：
The treatment by biodegradation of phenols wastewaters resulted from a petrochemical platform was studied. The purpose of this work was to establish the parameters that influence the phenols biodegradation process and to find out the optimum points for system working. During more than one thousand days of experiments was obtained the system answer at changing of the pH, biomass concentration and nutrient concentration. It was settled the phenols removal efficiency and the final phenols concentration at the changing of the parameters above mentioned. In the end, it was established an optimum running unit interval related to the pH, biomass concentration and nutrient concentration for running the system in conditions of best phenols removal efficiency and final phenols concentration below the maximum admissible phenols concentration (0.3 ppm)..
