Under the same total alkalinity, the absorbing rate of the regenerated spent caustic liquid (or mass transfer factor) is directly related with the OH concentration.

Comparing with the other models, the new model is closer to real status and the expression of mass transfer factor is obtained, which coincide with that obtained by experiment and lays a foundation for improving the mass transfer effect in actual use.

Using the mass transfer and biological reactions principles, a useful and simplified integrated biological process and mathematical model is established, in which the overall mass transfer factor, η_t, can be determined by measuring actual bio-reaction and inherent bio-reaction rate in the packing tower used.

A complex process of mass transfer and bio-reaction among three phases in biological packing tower was reduced reasonably to an effective bio-reaction process and its mathematic model was obtained. A synthetic (parameter) of the model-overall effective mass transfer factor can be determined by measuring actual bio-reaction rate and inherent bio-reaction rate.

A new model for mass transfer of air bubble in water is established. Comparing with the other models, the new model is closer to real status and the expression of mass transfer factor is obtained, which coincide with that obtained by experiment and lays a foundation for improving the mass transfer effect in actual use.

Using the mass transfer and biological reactions principles, a useful and simplified integrated biological process and mathematical model is established, in which the overall mass transfer factor, η_t, can be determined by measuring actual bio-reaction and inherent bio-reaction rate in the packing tower used.

Using the mass transfer and biological reactions principles, a useful and simplified integrated biological process and mathematical model is established, in which the overall mass transfer factor, η_t, can be determined by measuring actual bio-reaction and inherent bio-reaction rate in the packing tower used. The effects of COD_ Cr and rate of influent of restaurant wastewater on the overall effective mass transfer factor were studied experimentally. The results showed that a bigger overall mass transfer factor can be obtained at a higher COD_ Cr in influent of restaurant wastewater and further increased with the increase of wastewater flow rate.
