Abstract：

For controlling reaction conditions ，adsorptive kinetics and equilibrium models were investigated by experiment with compound activated sludge-biofilm reactor. The results showed in 30mins biofilm attached met the reversible dynamic model； Biofilm adsorption process followed t he the second model； The equilibrium data fitted the Langmuir biosorption isotherm better than Freundlich.
