Abstract:

This study is interested on the evaluation of the diagnostic of the treatment station (activated sludge) of used waters of oil rejects of the Company SAMIR so as to identify stops on which one can act to improve favors the output of elimination pollution. The optimization of the processing physico-chemical by coagulation-floculation has allowed to improve the output of elimination of the organic pollution by the biological processing. Results obtained by adopting an aeration some continuous shows the functioning of treatment station. Nevertheless followed it by the indication of muds in the course of the time shows that the value of the former can reach 25 % what justifies the efficiency of the biological processing. The measure of parameter DCO and DBO5 of waters processed to the exit of the clarificateur watch that the DCO varies around 100 mg∙L-1 and the DBO5 varies between 40 and 50 mg∙L-1. Matters in suspension are well eliminated by the biological processing. Furthermore, results obtained during followed it by the development of the biomass in the basin of aeration have shown that microorganisms remain well. This allows to degrade correctly and an efficient manner hydrocarbons in the biological basin.
