And a drying unit 107. The developing section 104, the fixing section 105, and the water washing section 106 constitute the tanks 104a, 105a, and 106a so as to store the developer, the fixing solution, and the flushing water, respectively. In addition, the film passes through the spaces of the detection unit 103, the developing unit 104, the fixing unit 105, the water washing unit 106, and the drying unit 107 through the feed rollers 108 arranged in a plurality. The feed rollers 108 are arranged in a zigzag manner to maximize the contact between the developer, the fixer, and the wash water with the film as the film passes.

Therefore, when the X-ray film is input through the detection unit 103, the X-ray film is introduced into the water tank 104a of the developing unit 104 along the feed roller 108 and developed by contact with the developer. . That is, the developer in contact with the surface of the film forms an image by reducing the silver substance exposed to the film to turn into a metal. The film passing through the developing unit 104 is continuously introduced into the water tank 105a of the fixing unit 105 and fixed by contact with the fixing liquid. In addition, the X-ray film is introduced into the water tank 106a of the water washing unit 106, washed with water for washing the developer and the fixing solution on the surface, and then introduced into the drying unit 107, and dried. do.

However, in the X-ray film developing machine 101 as described above, the developing waste solution and the fixing waste solution can be extracted from the resources such as silver, and are separately collected and consigned to a wastewater treatment company, but a small amount of chemicals, gelatin and scales are used. In the case of the mixed wash water, the amount is 3-6ℓ per minute, about 1 ton per day, the waste water purification process is difficult, and the cost burden is excessive.

Accordingly, the developer washing water is discharged to the sewer. As compared with the developing solution and the fixing solution, the washing water must be used in a large amount to improve the quality. There is a problem that the amount to be discharged is increased to increase the environmental pollution, as well as waste of water.

Therefore, the present invention has been made in order to solve the above problems, by reducing the cost burden due to the waste water treatment of a large amount of washing water by filtering and recycling the washing water flowing from the developer after washing the X-ray film. The purpose of the present invention is to provide an automatic developing water treatment apparatus for minimizing the environmental pollution and water waste caused by just throwing the flushing water into the sewer.
