摘要: The biological aerated filter (BAF) was used to treat the oil-field produced water. The
removal effi-ciency for oil, COD, BOD and suspended solids (SS) was 76.3%—80.3%, 31.6%—
57.9%, 86.3%—96.3% and 76.4%—82.7%, respectively when the hydraulic loading rates varied
from 0.6m•h-1 to 1.4m•h-1. The greatest part of removal, for example more than 80% of COD
removal, occurred on the top 100cm of the media in BAF. The ki-netic performance of BAF
indicated that the relationship of BOD removal efficiency with the hydraulic loading rates
in biological aerated filters could be described by cr/ci=1-exp(-2.44/L0.59). This
equation could be used to predict the BOD removal efficiency at different hydraulic loading
rates.
