| titleOfInvention | Method for vacuum evaporation of photographic waste liquid |
| abstract | (57) [Summary] [Objective] The drawbacks of the conventional method for treating photographic waste liquid by vacuum distillation are solved, and unlike the conventional method, without the use of chemicals, it is more effective, convenient, and high-performance. A vacuum evaporation method for removing volatile components to a level is provided. [Structure] In the waste liquid treatment, which consists of condensing the photographic waste liquid under reduced pressure by evaporation and condensing the vapor generated at that time to separate it into a concentrated waste liquid and a dilute condensate, contact air with the condensate at 40 to 80 ° C. A method for vacuum evaporation of photographic waste liquid, which removes ammonia in the condensate. In addition, air 1 is added to the condensate 7. A method for evaporating a photographic waste liquid under reduced pressure using a countercurrent wetting wall tower 9 as a means for removing the ammonia in the condensate by bringing them into contact with each other. |
