| 摘要 |
The invention concerns a method for recuperating vent gas coming from an ozonization reactor, in a plant treating effluents in particular of waste water comprising in the following order or otherwise, a biological reactor (10), a clarification tank (12) and an ozonization reactor (14), characterised in that: the vent gas coming from the ozonization reactor is contacted, countercurrent, with a flow of water containing compounds oxidizable by the ozone for efficiently consuming and eliminating the residual ozone; the vent gas free from residual ozone is then, optionally, scoured using the water taken from the clarification tank, for producing a gas/liquid mixture; said gas/liquid mixture is transformed into an emulsion of very fine bubbles; and said emulsion is introduced in the biological reactor in the proximity of the latter.
