Abstract: The research was studied on removal of organic matter (COD) and hcavy metals (Copper; Cu and Zinc; Zn) by using sequencing batch reactor - granular activated carbon (SBR- GAC) systcm. Thc experiments were carried out by using synthetic wastewater, had COD concentration as 400 mgL and hcavy metal concentration (Cu and Zn) as 10 mgL. The experiments were separated in 3 pants as adsorption capacity, dosing of granular activated carbon (500, 1,000, 1,500, 2,000 and 2500 mgL) in SBR system and hydraulic retention time (HRT) of the system. , The results showed that the adsorptiou capacity of granular activated carbon (GAC) for COD, Cu and Zn were 657.698,45.836 and 37.763 mg/gGAC rcspectively. It was found that the efficiencies of SBK-GAC for rcmoval of COD, Cu and Zn during 8 day from starting the systcm did not show any different froin normal SBR system. But after 8 days of operation. The rcnioval eflicicncics for COD, Cu and Zn in SBR-GAC wcrc liighcr than in the nor~nal SBR system. When the hydraulic retention time (HRT) was considered, The COD, Cu and Zn concentrations in the effluents from SBR-GAC system which was operated under HRT of 3, 5 and 10 days, respcctively, were 67.800, 44.700 and 24.600 mgL, 0.236, 0.137 and 0.088 mg/L and 1.204, 0.933 and 0.450 mgL rcspcctively. On the other l~and the COD, Cu and Zn concentrations in the effluents from normal SBR system werc 79.400, 74.600 and 23.600 mg/L, 0.438, 0.212 and 0.208 mg/L and 1.248, 1.148 and 1.416 mg/L respectively. From the results aboved, we could conclude that normal SBR system could be used for treating COD, Zn and Cu I in the wastewater But, when the HRT and efficiency of the syetem were considered, SBR-GAC system could be applied for reduction of the HRT and increasing of the efficiency.
