Abstract

The impact of Ni²⁺ on the aerobic granular sludge (AGS) system was explored by inoculating the return sludge from A²/O process of a municipal wastewater treatment plant in sequencing batch reactor (SBR). The mature AGS cultured at 25℃ for about 50 days had a morphology of sphere or ellipsoid with a small number of filamentous bacteria on the surface, and a particle size of 2~4mm. The AGS system keeps a mixed liquid suspended solids (MLSS) of 6000mg/L and sludge volume index (SVI) at 40~50mL/g. Ni²⁺ in the concentration range of 0~2mg/L will improve the stability of AGS, increase MLSS, and decrease SVI. Meanwhile, the extracellular polymeric substances (EPS) in AGS increased with the addition of Ni²⁺and contained significantly more protein (PN) than polysaccharide (PS). The inhibition of Ni²⁺ on removal of total nitrogen (TN) by AGS was greater than that of chemical oxygen demand (COD). Finally, the removal rate of COD and TN could be maintained above 95% and 70%, respectively.

Key words： AGS nickel ion extracellular polymer removal efficiency
