The phosphorus removal experiment implies the increasing 100 mg/L MLSS concentrations can remove about 1 mg/L TP. The phosphorus removal efficiency can be improved by the increasing rate of MLSS concentrations. When everyday increasing rate of MLSS concentrations are about 500mg/L, the phosphorus removal efficiency would higher than 90%, effluent TP would be lower than 1 mg/L. When MLSS concentrations are fluctuating, effluent phosphorus would fluctuate correspondingly. Everyday the amount of discharging excess sludge can be prejudged by the amount of influent TP.
