る。Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to processing waste liquid (abbreviated herein as photographic processing waste liquid or waste liquid) generated during the processing of photographic light-sensitive materials using an automatic photographic processor. The present invention relates to a method for processing waste liquid of photographic processing suitable for processing by disposing in or near an automatic processor, and a processing apparatus suitable for use in carrying out the method.
[発明の背景]

を用いた工程を組合せて行なわれている。[Background of the Invention] In general, photographic processing of silver halide photographic materials includes development, fixing, and water washing in the case of black and white materials, and color development, bleach-fixing (or bleaching, fixed M) in the case of color photographic materials. A combination of processes using a treatment liquid having one or more functions such as , water washing, and stabilization is performed.

によって処理液の性能を一定に維持する手段が採られて
おり。In photographic processing in which a large amount of light-sensitive material is processed, the components consumed during processing are replenished, while the components that are concentrated by elution or evaporation into the processing solution (
Measures have been taken to maintain the performance of the processing solution at a constant level by removing bromide ions in the developing solution and silver complex salts in the fixing solution to keep the processing solution components constant.
上記補充のために補充液が処理液に補充され、上記写真

廃棄されている。A replenisher is added to the processing solution for the above replenishment, and a portion of the processing solution is discarded to remove the thickening components in the photographic processing.

あるが、写真処理廃液は自動現像機の処理槽から排液管

で稀釈されて下水道等に廃棄されている。In recent years, systems have been changing to systems in which the amount of replenishment of processing solutions, including washing water, has been significantly reduced due to pollution and economic reasons. It is then diluted with waste water from washing water or cooling water from automatic processors and disposed of in sewers, etc.

に不可イ七となっている。このため、各写真処理業者は
廃液を専門の廃液処理業者に回収料金を払って回収して
もらったり公害処理設備を設置したりしている。However, due to the recent tightening of pollution control by the Water Pollution Control Law and the ordinances of each prefecture, it is possible to dispose of washing water and cooling water into sewers or rivers, but other photographic processing solutions [e.g. It is virtually impossible to dispose of standard liquids (color developing solution, bleach-fix solution (or bleach solution, fix solution), stabilizer solution, etc.). For this reason, each photo processing company pays a collection fee to a specialized waste liquid processing company to collect the waste liquid, or installs pollution treatment equipment.

。However, the method of outsourcing to a waste liquid treatment company requires a considerable amount of space to store the waste liquid, and is also extremely expensive.Furthermore, the initial investment (initial cost) for pollution treatment equipment is extremely high. It has drawbacks such as being large and requiring a fairly large area to maintain. More specifically, the activated sludge method (for example,

きい利点が発揮される。On the other hand, due to constraints from water resources, rising water supply and drainage costs, the simplicity of automatic processor equipment, and the work environment around automatic processors, in recent years stabilization treatment has been used instead of washing with water, and Photographic processing using automatic developing machines (so-called waterless automatic developing machines) that do not require piping for water supply and drainage is becoming popular. In such processing, it is desired that cooling water for controlling the temperature of the processing liquid can also be omitted. In such photographic processing that does not substantially use water submersion or cooling water, the photographic processing waste liquid from the automatic processing machine is not diluted with water compared to the case where water washing is used, so the pollution load is extremely large. It has the characteristic of being small in quantity. Therefore, since the amount of waste liquid is small, piping outside the machine for supplying and draining liquid can be omitted. As a result, it is difficult to move after installation to install piping, the leg space is small, piping work at the time of installation requires a large amount of money, and energy costs for hot water supply are required. All of the machine's shortcomings have been eliminated, and it has the extremely great advantage of being made compact and simple enough to be used as an office machine.

の廃液の処理は、近年益々大きな問題となりつつある。However, on the other hand, the waste liquid has an extremely high pollution load, and it is completely impossible to dispose of it not only in rivers but also in sewers in accordance with pollution regulations.
Furthermore, although the amount of waste liquid in such photographic processing (processing that does not substantially involve water washing) is small, even in relatively small-scale processing, for example, in the processing of X-ray photosensitive materials, 10 times a day! L. The processing of photosensitive materials for printing and plate making amounts to about 3,041 units per day, and the processing of color photosensitive materials requires approximately 50 units per day, and the disposal of the waste liquid has become an increasingly big problem in recent years.

and could not satisfy the demand for pollution-free production. In recent years, the amount of evaporation tends to increase further due to lower replenishment amounts, lower renewal rates due to compact laboratories, and higher temperature processing of processing solutions due to faster processing, and therefore the above-mentioned drawbacks tend to be further magnified. .

This is thought to occur when ammonium thiosulfate and sulfites (ammonium salt, sodium salt, or potassium salt), which are often used as fixing solutions and bleach-fixing solutions in photographic processing solutions, decompose due to high temperatures. Further, during the evaporation process, moisture and the like in the photographic processing waste liquid becomes vapor and gasifies, thereby expanding the volume and increasing the pressure in the evaporation pot. Therefore, this pressure causes the harmful or malodorous gas to leak out of the evaporation treatment device.

ど不可能である。In this case, the evaporation process itself cannot be carried out, and if there is no means C, the steam will condense and condense at the exhaust means E, rendering the exhaust means ineffective.Furthermore, if there is no means D, The waste liquid evaporates and the condensed aqueous solution and organic solvent are discharged to the outside.The inventors have conducted various studies and found that sulfur dioxide gas and hydrogen sulfide gas are dissolved in the condensed aqueous solution. Furthermore, it was found that organic solvents and organic acids such as ethylene glycol, acetic acid, diethylene glycol, and benzyl alcohol, which came out as gases through an azeotropic phenomenon with water in the photographic waste liquid, also distilled out as fractions. For this reason, condensed water has high pollution values such as BOD and COD, and it is almost impossible to discharge it as it is into external sewers or rivers.

う。Furthermore, if there is no means E, the volume will expand significantly due to water vaporization during the evaporation process, and the pressure in the evaporator will increase, causing harmful gases to leak to the outside or causing the evaporator to overheat. This could lead to pressure and become a dangerous situation.

Therefore, in the color development processing process, it is usually necessary to include a color developing agent in the color developing solution, but color developing agents are incorporated in the color photographic material. The color developing agent contained in the 0-color developing solution, which may be treated with a developer or an alkaline solution (activator solution), is an aromatic primary amine color developing agent, and is an aminophenol-based and p-phenyrezine amine-based color developing agent. Contains derivatives. These color developing agents can be used as salts of organic and inorganic acids, such as hydrochlorides, sulfates, phosphates, p-)luenesulfonates, sulfites, oxalates,
Use benzene disulfonate, etc. These compounds are generally present at a concentration of about 0.1 g to about 30 g per color developer 11, more preferably about 1 g per color developer 131.
