ABSTRACT:
Apparatus in which contaminants from the raw or waste waters are removed by combined biological-chemical degradation of such contaminants comprises first, second and third chambers. An aeration zone is provided in the first chamber. A slanted plate is located in the second chamber to define an aeration zone which overlies a sludge separation zone. Means for transferring such waters from the equalization zone to the upper region of the aeration zone is provided. The slanted plate provides for a downflow of waters through the aeration zone and an upflow of waters through the sludge separation zone, where due to the lower end of the slanted plate being spaced from the lower portion of the second chamber wall forms a constriction to the flow of waters to increase the rate of flow and form a fluidized bed of active media in the sludge separation zone. The height of the sludge separation zone is sufficient to dampen the upward flow of the waters to develop a quiescent region in the upper portion of the sludge separation zone. An upflow channel means is provided in the second chamber with its intake located in the lower region of the sludge separation zone and with its outlet located in the upper region of the aeration zone. Means for dispersing air into the active media which is circulated through the upward flow channel is provided. The third chamber has a clarifying zone. Means is provided for transferring the processed waters from the upper region of the sludge separation zone to the clarifying zone.
