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.

通过观察还发现，由于液体分布不均，生物膜在滴滤塔内生长分布不均，并且挂膜后，滴滤塔的孔隙率减小，两相流动阻力比空塔时的大，可采用流动阻力的变化作为判断挂膜成功与否判据。3、首次将多孔填料塔简化成多个竖直毛细管并行排列构成的填料，应用两相流理论，结合生化反应动力学，并考虑氧的限制，建立了一个生物膜滴滤塔降解废气的毛细管模型，其结果与实验数据吻合得较好。
