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. |
