| Abstract: | Study on the liquid circulation velocity,organic matter degradation kinetics and bio film detachment rate in airlift biofilm suspension reactor was conducted.The results showed that the inner circulation velocity is proportional to the reactor height and the 0.5 power of the superficial gas velocity in the riser. The reactor can be treated as CSTR when inner circulation flux is high. The biofilm detachment rate is proportional to the first power of suPerficial gas velocity in riser and the biofilm thickness and the 2/3 power of carrier quantity in reactor,respectively. |
