Kinetic characteristic of single biological aerated filter (BAF) for organics degradation

摘要

The kinetic model of organic removal in single biological aerated filter for domestic waste water treatment was established, and kinetic parameter was calibrated under certain hydraulic loadings. The results showed that organic removal efficiency was affected by the concentration of the influent COD, hydraulic loadings and the height of filter media when the reactor size was unchangeable. It is found that the model was accurate in predicting the effluent quality by the experiment and it could afford new reference evident to optimize the treatment processes.
