摘要

•Textile wastewater was treated with sludge flocs and aerobic granules (AGS) in SBR.•Higher anaerobic and overall COD removal yields were observed in the AGS SBR.•High azo dye decolorization was attained with both flocs and aerobic granules.•Decolorization products showed higher cyto- and genotoxic potential than original dye.•AGS had better performance in decolorization product detoxification potential
