Abstract of corresponding document: WO9429227
A process is described for purifying waste water containing sulphide, comprising oxidising the sulphide to elemental sulphur in a reactor with sulphide-oxidising bacteria in the presence of oxygen, and separating from the waste water at least a part of the sulphur formed during the oxidation, while recycling a part of the elemental sulphur separated from the reactor effluent into the reactor in such a way that a concentration of elemental sulphur of at least 1 g/l is maintained in the reactor. The sulphur, in the form of aggregates, is used as a carrier material for the sulphide-oxidising bacteria.
