Abstract:

The performance of organics and nitrogen removal as well as sludge reduction were investigated in a novel catching bed biofilm reactor which applies to decentralized wastewater treatment. The results indicate that the average removal rate of COD reached to 81.7% with different hydraulic retention time (HRT); Even HRT was only 2.94h, the average volumetric loading of NH 4+-N and TN were 0.65 kg/(m3·d) and 0.81 kg/(m3·d), the removal efficiencies of NH4+-N and TN reached the climax about 74.7% and 65.2%. Protozoa and metazoan were observed on the biofilm and suspended sludge. The sludge yield was roughly achieved as 0.1465Kg MLSS/KgCODremoved, which was only about 50% of the conventional aerobic processes. © 2009 ASCE.
