METHOD AND DEVICE FOR THE PROCESSING OF LIQUID WASTE FROM THE PHOTOGRAPHIC DEVELOPMENT. |
| abstract |
The invention describes a method and apparatus for the treatment of liquid residues from photographic treatments in which the residues to be treated are: (a) subjected to oxygen oxidation (3) as well as (b) to oxidation of oxygen. ozone (7), (c) the haloid ions are optionally removed from the oxidized residues, (d) the residues, from which a large quantity of haloid ions is optionally removed, are subjected to anodic post-oxidation as well as to (15 ) (e) cathodic reduction (17), then (f) neutralized (19) and (g) released by filtration (22) of the aforementioned solids. The invention makes it possible to particularly effectively reduce the harmful substances produced during photographic processing. |
