A METHOD AND A DEVICE FOR TREATING EFFLUENT SEAWATER FROM A SEAWATER SCRUBBER

摘要

A gas cleaning system including a wet scrubber (14) for removal of sulphur dioxide from a gas and an oxidation basin system (42) for receiving effluent generated in the removal of sulphur dioxide from the process gas. The oxidation basin system (42) comprises an oxidation basin (43) for containing the effluent during treatment thereof, an oxygen supply system (47) for supplying oxygen to the effluent in the oxidation basin (43), and a contacting system for bringing the effluent into contact with an enzyme which catalyses the oxidation of bisulphite and/or sulphite ions.
