Algal bloom in lakes and reservoirs caused by eutrophication has raised wide public concerns in recent years. In this investigation, algae leachate was treated using a biological aerated filter (BAF) on laboratory scale for the first time, and the effect of hydraulic loading had been studied. The results showed that the optimum hydraulic loading was 0.65m3/(m2xh). At the optimal hydraulic loading of 0.65m3/(m2xh), the average values of COD, NH4+-N, TN, TP and MC-LR in effluent were 29.04mg/L, 36.33mg/L, 5.07mg/L and 0.57mg/L respectively, and the average removal efficiencies were 45.5%, 90.8%, 40.52%, 15.4% and 77.1% respectively. The concentrations of COD and ammonia nitrogen for the effluent both achieved Standard A of the "Discharge standard of pollutants for municipal wastewater treatment plant" and MC-LR of the effluent was lower than the limit of the "Standards for drinking water quality" of China.
