摘要： A device for treating a liquid comprises a chamber (12) and a cavitation element (18) arranged in a rotatable manner in the chamber (12). According to a first aspect, the cross-section of the chamber (12) has varying curvatures (34, 36) in the region of the cavitation element (18). According to a second aspect, the substantially disc-shaped cavitation element (18) has preferably elongated passages (44) which have rounded inner walls.

摘要： According to a method for treating a liquid, a liquid to be treated is fed into a chamber (12), a mechanical cavitation element (17) acts on the liquid upon delivery of gas in the area of the surface of the cavitation element (17) and introduces the gas into the liquid by means of movement of the cavitation element (17), and sound waves are directly introduced into the liquid by means of at least one acoustic power converter (26, 28).

摘要： The invention relates to a method for the treatment of a sulphide-containing spent caustic by chemical reaction of the sulphides, wherein the process comprises the following steps: introducing the spent caustic into a reaction chamber (18) which comprises at least one acoustic power transducer (22) and a cavitation element (20); treating the spent caustic with ultrasound from the at least one acoustic power transducer (22), feeding an ozone-containing gas mixture into the reaction chamber and distributing the ozone-containing gas mixture in the spent caustic, using the cavitation element (20); wherein the sulphide-containing spent caustic is reacted with the ozone-containing gas mixture, forming non-sulphidic inorganic sulphur compounds.
