Abstract—Biosorption anic pollutants, expressed as COD, local wastewater treatment plant, which situates in HeFei City,
by aerobic and anaerobic sludge was conducted to examine Anhui Province, China. The wastewater sample was also
equilibrium and ic models. Freundlich and Langmuir collected from the influent of the plant, and its COD
models were mostly used for mathematical description of the concentration is ranged from 200mg/l to 400mg/l.
biosorption equilibrium. Freundlich equation was more fit to
describe the equilibrium of biosorption process in this study. The sludge was used on the same day as it was sampled.
Under the same experimental condition, biosorptive capability of Immediately after arriving at the lab, the biomass was washed
aerobic sludge was greater than that of anaerobic sludge. The to remove background electrolytes and previously adsorbed
biosorption processes by aerobic and anaerobic sludge anics. After the mixed liquid settled, the supernatant water
governed by intraparticle diffusion. For both anaerobic and was decanted and replaced with double-distilled water.
