    摘要: Decribed are a process for the treatment of liquid residues from photographic processes, in which the residues are oxidized in stages and precipitated solids are then separated out, and in which the residues to be treated are subjected to:

    (a) oxygen oxidization and
    (b) oxygen-supported mild anodic oxidization and then
    (c) ozone oxidization and
    (d) are freed of precipitated solids by filtration after pH value setting and loading of auxiliary substances
    and a device for performing this process.

    摘要: Decribed are a process for the treatment of liquid residues from photographic processes, in which the residues are, where necessary after dilution, oxidized in stages with oxygen and ozone and where precipitated solids are, after pH value setting and the addition of auxiliary substances, separated by filtration from the oxidized residues, and a process for performing this process. In the new process, the residues to be treated are subjected to the following process stages:

    (a) oxygen oxidization,
    (b) oxygen-supported mild anodic oxidization and
    (c) a further complete anodic oxidization with current intensities higher than in (b),
    (d) in a manner known per se to an ozone treatment and in stage
    (e) the precipitated solids are separated in a manner known per se.
