<p>In a process for purifying substantially organically polluted waste water, the waste water is evaporated and condensed within a primary system and a secondary agent within a closed secondary system containing a condenser and spatially separated from the primary system, whereby the waste water is evaporated by heating at the secondary agent previously heated further in the condenser and the latter is evaporated in the secondary system by the condensation of the waste water vapour. Here the waste water vapour is taken through a cyclone and the depleted waste water sump solution obtained in the evaporation of the waste water is removed. The latter takes place dependently upon the superheating temperature of the secondary agent on the pressure side of the condenser and when this exceeds a set value the waste water is simultaneously fed into the primary system depending on its filling level. It is thus possible even with such polluted waste water to produce a continuous process in a technically simple manner.</p> |
