Method for evaporation treatment of photographic processing waste solution and device
therefor |
(57) Disclosed is a method for treating a photographic processing waste solution which
comprises evaporating a photographic processing waste solution by heating and cooling
a vapor generated by the heating by use of a cooling device to obtain a distilled
solution, and a treatment device therefor which comprises a treatment tank for performing
heating treatment of the photographic processing waste solution, a device for discharging
the heated and concentrated solution of the photographic processing waste solution
from the treatment tank, a receiving tank for the discharged solution, a device for
performing cooling treatment of vapor generated by the heating treatment, a recovering
tank for recovering a distilled solution generated by the cooling treatment, and a
control device for controlling heating treatment according to the progesss of treatment
of the waste solution.
