Abstract :
Brewery wastewater treatment by three-phase bio-fluidized bed was studied, as well as the effects of aeration quantity and hydraulic stay time. It was found that the optimal aeration quantity is 0.25 m3/h, and the optimal hydraulic stay time is 1.5 h. Under such operating condition, the average removal ratio of COD reached above 85% and the biological concentration reached 28.31 mg/L. It is proved that the bio-membrane is active and the reactor has strong capability to resist impact load.
