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.

通过对反应器的除磷效果的研究，发现污泥浓度增长100 mg／L能去除将近1 mg／L TP；发现随着污泥浓度增长速率的增加，除磷效率相应提高；当污泥浓度的增长速率增加到每天500 mg／L时，磷的去除率将高于90％，并且出水TP浓度将低于1 mg／L；发现每天排放的剩余污泥量可以根据进水TP浓度来决定；发现最佳好氧与厌氧时间比T_是0.5；溶解氧冲击指数DO_I被首次提出，作为分析溶解氧DO影响的指标。

It takes about 50d for full-scale anoxic variable rate biofilter with microbe-catalyzed media to finish start-up at 22~28C.
