When pH is litmusless, the purification efficiency is the largest. The unhomogeneity of liquid flow results in the uneven biofilm growth. The flow resistance after start-up is significantly larger than that before start-up, whichprovides a method to monitor the biofilm growth.3、The packed bed is simplified to a series of straight capillary tubes covered by the biofilm. The two-phase flow and mass transport, biochemical reaction kinetics, and the limitation of oxygen are taken account of in this model. The results of model are basically in agreement with the experimental data.
