The aim of this study was to evaluate the performance of pilots physical, biochemical and chemical, in series and together for waste water treatment plants, processing oil in the Persian Gulf’s oil and gas. For this purpose a Skimmer tank, MBBR reactor, Nano reactor, UV tank was used. Incoming wastewater system effluent desalination unit. Hydraulic retention time for various different system is intended. If you reduce the retention time of 18 to 12 hours, removed COD from 91% to 76% reduced. It was also found that the total removal of carbon materials in part MBBR 78.2% and 21.8% of the biofilm floating microorganisms. The results indicate that the whole system, which consists of 4 pilot that each part of its eliminates COD in waste water, the ability to remove 91% of COD. Solution input load 1.766 Kg COD/m2 was signed. Finally, after the passage of treated wastewater and filters in 4 stages, has a relatively uniform quality and desirable.
