Abstract
A method and apparatus are disclosed for treating process water which is loaded with gaseous compounds and/or possibly with solids and comes from a wet-cleaning installation for cleaning process gas, e.g., from a melt-reduction subassembly or from a direct-reduction subassembly. Process water is introduced in a tank in a first process stage and degassed on the basis of reduced solubility of the dissolved compounds. The tank has, on its upper side, a gas-collecting chamber, in which the separated-off gases are collected and from which these are discharged. Likewise, the treated process water is discharged from the tank via a drainage means.
