摘要
Reactor for oxidation and biological reduction of liquid to be treated by upward circulation and recirculation, comprising, in a vertical lengthwise enclosure (5) accessible by an entry (9), a lower biomass fixation layer (1) made of a material with a density lower than that of the liquid and an upper biomass fixation layer (3) made of a material with a density higher than that of the liquid, characterised in that the lower layer (1) is separated from the upper layer (3) by a transverse partition (2) forbidding the passage of the filtering materials between a lower zone situated under the partition (2) and an upper zone above the partition (2), a delivery of oxidising gas (8) provided under the upper layer (3) and above the partition (2), an output (10) of the treated liquid and recycled by a pump (12) and external piping (11) to the entry (9). …IMAGE…
