Abstract :

Background and objective: Petrochemical industry as well as some other industries is one of the environmental pollution which polluttted wastewater with ammonia nitrogen. The objective of this study was two-step ammonia nitrogen removal from Kermanshah Petrochemical effluent using native bacteria immobilized on granular activated carbon. Method:This study conducted in continuous mode using two reactors with effective volume of 1.7 l for each reactor. These  reactors operated as up-flow and fixed film. Granular activated carbon immobilized with nitrifier and denitrifire bacteria has been used as media. Initial concentrations of ammonia  and  nitrate (50-200 mg/l) with retention time (1-3 h) at pH 8 and temperature of 28 ± 3 ° C were studied.  Findings:Results showed that with increasing in retention time in both reactors nitrification and denitrification efficiency increased. The maximum nitrification and denitrification rates were 2.69 Kg NH4+/m3.d and 2.49 Kg NO3-/m3.d respectively. Maximum nitrification and denitrification rates occurred at 3h retention time and ammonia and nitrate removal efficiency were achieved 99.5 percent. Discossion and Conclusion: This study has been showed that native bacteria immobilized on granular activated carbon and use of that in a continuous up-flow attached-growth reactor for the removal of ammonia has a high efficiency.
