  7. Abstract:
  8. Due to the increasing relationships, and expand the transportation of goods and fuel by ships and other factors may also cause the release of pollution into the sea, Oil and also its derivatives are the dangerous pollutants that threaten the health of the environment and may destroy the local ecosystem.One of its highly carcinogenic pollutants that even inhaled,is furfural. A new and efficient method for the filtration of toxic substances and hazardous wastewaters, using the moving bed biofilm reactor treatment that is MBBR system. Microorganisms present in the reactor, that was used in this project, from the microorganisms of industrial Behran Company. Removal of furfural from the harsh conditions of salinity in the reactor with BBRC-9004 microorganisms was grown in vitro to the environment, Sharif University Research Institute for biological Bank.In this experiment that was tried in removal efficiency with different concentrations of salts, furfural and other factors in four Hydraulic retention times (HRT) of 24, 16, 12, 8 hours. Filling of packing inside the reactor was 40%. The optimal concentration of furfural in all situations was 600 mg / liter. The range of salt concentrations up to 60 gr / litr was considered. In this project was considered the ability of bacteria in replacement packing, the effect of furfural concentration, HRT, the hydraulic shock, furfural concentration shock and also influence of these parameters on the amount of outlet furfural concentration, COD concentration and comparing the results with stover-kincannon.
    The efficiency of COD and furfural removal in the best situation in 24-hr HRT, were respectively, 99.2% and 99.8% that decreased with increasing salt and furfural concentration, while the efficiency of COD removal was reached to 75% in 8- hr HRT, 800 mg /liter inlet furfural with the presence of 60 mg /liter salt in bioreactor
