摘要：Brassware wastewater is classified as the most dangerous effluent, in particular when it is directly discharged in the receiving environment. The aim of this work is to study the biological pathway treatment of effluents at low and medium organic load with sequencing batch reactor (SBR). The effluents characterization have shown a high concentratio n of metallic load such as silver (3.05 mg/L), copper (10.64 mg/L), nickel (150.94 mg/L), and organic load with the an average COD of 4000 mg/L. The SBR has been used in a 24 hours cycle for 22 hours of aeration and 2 hours of tailing. The results have shown a significant reduction in COD and BOD 5 for both low and medium applied organic loads. The COD removal rates present 81 and 74%, while the BOD 5 abatement reaches 86 and 81% at low and medium organic load, respectively. The abatements observed for heavy metals such as Ag, Cu and Ni with low and medium load were 32.87, 41.42, 30.98 % and 27.77, 34.63, 26.06% respectively. The efficiency SBR results have been affected by the presence of both high heavy metal s co ncentrations and increased organic load in real effluent brassware
