ABSTRACT:
An improved method and apparatus for treating liquor containing biodegradable wastes wherein the liquor is first delivered to a quiescent primary settling zone and then to an aeration zone. The aerated liquor is delivered downwardly through a column of submerged fixed media having a high surface area to volume ratio so that aerobic microorganisms can grow on their surface. The liquor is recirculated through the aeration zone and fixed media, and is withdrawn from the unit after treatment. A portion of the aerated liquor from the top of the fixed media is recycled back into the primary settling zone to denitrify the nitrate rich aerated liquor by deoxygenating the dissolved nitrates and to equalize the BOD load in the secondary aerobic treatment zone.
