OXIDATION AND BIOLOGICAL REDUCTION REACTOR, BIOFILTRATION METHOD AND WASHING METHODS USED IN THIS REACTOR |
摘要 |
The present invention concerns an oxidation and biological reduction reactor for liquid to be treated by upwards circulation and recirculation including, within a longitudinal vertical enclosure 5 accessible by an admission 9, a lower layer 1 of biomass fixation made of material whose density is lower than that of the liquid and an upper layer of fixation 3 of biomass made of material whose density is higher than that of the liquid, characterized in that the lower layer 1 is separated from the upper layer 3 by a transverse wall 2 preventing the passage of filtration materials between a lower zone located under the wall 2 and an upper zone above the wall 2, an oxidation gas input 8 under the upper layer 3 and above the wall 2, an outlet 10 for the treated liquid is recycled by a pump 12 and an outer pipe 11 on the inlet 9.
