Aerobic Granular Sludge for Lead Ion Adsorption and Desorption by LIU Yong, CHENG Yuanyuan, ZENG Lingcong, ZHANG Yuhang, ZENG Minjing, ZENG Yu, LI Zhenghao, WU Junfeng, LONG Bei

“…The Pb²⁺ adsorption by aerobic granular sludge (AGS) and the ammonium salt desorption are investigated,which aims to provide technical support for the treatment of wastewater from ionic rare earth mines.The influence of Pb²⁺ concentration and adsorption time on the adsorption performance is explored by the single-factor experiment.Then,the Pb²⁺ adsorption capacity and rate of AGS are studied by the thermodynamic model and kinetic model.Finally,ammonium chloride with a concentration of 0.1~2.0 mol/L is employed to desorb AGS.When the initial Pb²⁺ concentration in wastewater is less than 80 mg/L,the adsorption efficiency is close to 100%.During the first 60 min of the adsorption,the concentration of Pb²⁺ decreases rapidly,but the decreasing trend gradually slows down after the first 60 min.The Pb²⁺ (20~1 000 mg/L) adsorption by AGS (2 690 mg/L) is in line with the Langmuir model (R² equals 0.998,and the saturated adsorption capacity is 55.37 mg/g) and the pseudo-second-order kinetic model (R²= 0.999).The adsorption efficiency of AGS is close to 100% for the first time and decreases to 38.2% for the fifth time.The desorption efficiency is 78.5% for the first time and declines to 39.9% for the fifth time.After five rounds of adsorption and desorption,the granulation rate of AGS is still above 97%,which indicates that AGS has the potential for repeated adsorption of Pb²⁺.…”
