Effect of Water Flow Pattern on the Treatment of Discharged Sewage by Biological Accelerator-Bio-Film Process

Abstract:

The paper studied the effect of water flow pattern on the treatment of disorderly discharged sewage in tidal rivers by bio-film process. The results indicated that biomass was greater under the fluctuation turn flow than under the folding flow around. Under the fluctuation turn flow, the concentration of COD was 168mg/L and the removal rate of COD was 37.1%. Under the folding flow around, the concentration of COD was 187mg/L and the removal rate of COD was 29.4%. The results indicated that the removal rate of COD was higher 7.7% under the fluctuation turn flow than under the folding flow around. The reason was that under the fluctuation turn flow, soft packing fiber was derided by water, and the effective use of surface area was great and microbial growth space was large.
