2. Description of the Related Art Generally, photographic processing of a silver halide photographic light-sensitive material is carried out by developing, fixing and washing with a black-and-white light-sensitive material, and by color developing and bleach-fixing (or bleach-fixing) with a color light-sensitive material. , One of the functions of washing, stabilizing, etc., or 2
It is carried out by combining the steps using a treatment liquid having three or more. Then, in a photographic process for processing a large amount of a light-sensitive material, a component consumed by the process is replenished, while a component which is concentrated by elution or evaporation in the process solution by the process (for example, bromide ion in a developing solution, A means for keeping the performance of the processing solution constant by removing (such as silver complex salt in the fixing solution) and keeping the processing water component constant, and the replenishing solution is replenished to the processing solution for the above replenishment. Therefore, a part of the processing liquid is discarded for the purpose of removing the thickening component in the photographic processing.

In recent years, as a photographic waste liquid processing apparatus capable of reducing the amount of waste (waste liquid) as described above, Japanese Patent Laid-Open No. Sho 60-
As disclosed in Japanese Patent No. 70841, there is introduced a photographic waste liquid processing apparatus which heats a waste liquid to evaporate and solidify water.

Decompress at
An evaporative concentrator of a reduced pressure heat pump type has been introduced in which the liquid is boiled below a normal boiling point to take out a concentrate. Further, this depressurization heat pump type evaporative concentration apparatus employs a method in which condensed water condensed and liquefied in the cooling vessel is recovered in a sump by depressurizing means using an ejector and a liquid feed pump. That is, when the condensed water in the basin is pumped up by a liquid feed pump having a blade directly connected to a motor installed outside the basin and returned to the inside of the basin through the vertical pipe portion of the ejector, the vertical pipe The horizontal pipe section side orthogonal to the section is in a vacuum state. Therefore, when the mouth end of the horizontal pipe portion is connected to the condensed water outlet of the cooling kettle,
The condensed water is forcibly sucked and collected in the reservoir. This evaporative concentrator has an advantage that the concentrate can be taken out without generating hydrogen sulfide or the like because the evaporative concentrator evaporates under reduced pressure. The photographic processing waste liquid processed by the evaporative concentrator of the reduced pressure heat pump system becomes colorless and transparent water. An automatic photo processing system has been developed in which such a vacuum heat pump type evaporative concentrator is connected to an automatic photo developing machine.

First, the automatic photo processor 101 and the vacuum heat pump type evaporative concentrator 100 are operated to develop a photographic light-sensitive material and / or a paper and process the waste liquid discharged from the automatic photo processor 101. .

That is, the photographic processing waste liquid discharged from the automatic photographic developing machine 101 is sent to the storage tank 6 through the pipe 80. At this time, a pH adjusting agent according to the amount of the photosensitive material to be processed by the automatic photo processor 101 is added from the pH adjusting means 102 to the photographic processing waste liquid, and the pH of the photographic processing waste liquid is adjusted.
Is adjusted to 5 to 6.3. Next, the pH-adjusted water whose pH has been adjusted is supplied from the pipe 80 to the storage tank 6. In the storage tank 6, by the air blown from the degassing means 103,
The pH-adjusted water is degassed, where carbonate ions are released as a gas.

Next, the pumping means 7 is operated to inject the degassed water that has been degassed in the storage tank 6 into the evaporation tank 1 up to the required water level.

When the concentrate accumulated in the concentrate reservoir 15 is removed, the concentrate outlet 16 that has been sealed is opened, and the concentrate accumulated at the bottom of the evaporator 1 is taken out to the concentrate recovery container 19. By rotating the rotary blades 20 by the drive source 22 at the time of taking out, the work of taking out the concentrate can be efficiently performed.
