Then, in some implementations In this example, the process liquid 24 with a calibrated concentration is injected into at least one process bath (for example, the dyeing tank 12 and/or the cross-linking tank 13 ) of the processing equipment 1A. In some embodiments, when the processing reagent (for example, the optical adjustment agent of the dyeing tank 12 and/or the cross-linking tank 13) in the liquid in the process bath (for example, the dyeing tank 12 and/or the cross-linking tank 13) does not reach the When the concentration is predetermined, an additional amount of process liquid 24' is further added to the process bath to adjust the processing reagent in the liquid in the process bath to have the predetermined concentration. In some embodiments, the recovered process liquid 24 with calibrated concentration can be added to the dyeing tank 12 and the cross-linking tank 13 at the same time, and then different additional amounts of the process liquid 24' are added according to the predetermined concentration required for each process bath. to the dyeing tank 12 and the cross-linking tank 13 to respectively adjust the treatment reagents in the liquids in the dyeing tank 12 and the cross-linking tank 13 to have respective predetermined concentrations. In this way, the process waste can be recovered through the above steps and processed and reused in the process equipment 1A and the electrolysis device 10 .

In recent years, waste liquids are usually treated through coagulation, adsorption, filtration, ion exchange and other methods. However, not only is the time cost high, the recovery efficiency is not ideal, and the waste produced also poses a burden to the environment. For example, during the polarizing film production process, excess iodine and potassium iodide will be produced. Activated carbon is usually used to absorb the excess iodine, and potassium iodide is recovered by evaporation after pretreatment. However, activated carbon that has adsorbed iodine cannot be reused, which not only causes a waste of materials, but also produces waste that has a negative impact on the environment. In addition, the waste liquid generated during the manufacturing process also needs to be replaced in large quantities on a regular basis, which also has high costs and adverse effects on the environment.

According to some embodiments of the present disclosure, by integrating the process waste treatment and reuse system 1B into the process equipment 1A, the process waste generated in the process equipment 1A can be effectively recycled and reused, thereby significantly reducing the process cost.

For example, according to some embodiments of the present disclosure, iodine molecules/potassium iodide waste liquid from the optical film material (eg, polarizing film) manufacturing process can be used as the electrolyte, and the positive electrode 120 is made of Using activated carbon (i.e., adsorbent 30) from the optical film manufacturing process, the iodine molecules on the activated carbon can be reduced to iodide ions through an electrolysis reaction to be desorbed from the activated carbon and dissolved into the iodine molecules/potassium iodide waste liquid. After all iodine is desorbed from the activated carbon, activated carbon with virtually no iodine molecules/potassium iodide can be obtained, and the activated carbon can be recovered and re-invested in the optical film manufacturing process. Furthermore, the iodine molecule/potassium iodide waste solution can not only be used as an electrolyte to recover activated carbon, but can also be purified and recovered through electrolysis reaction and/or electrodialysis reaction. The recovered iodine molecule/potassium iodide solution can be re-invested in the polarizing film production process. In this way, by manufacturing optical films (for example, polarizing films) through the process system 1 that integrates the process equipment 1A and the process waste treatment and recycling system 1B, there is no need to Additional waste liquid will be generated, and the waste liquid from the recycling process equipment 1A can also be processed.

Furthermore, according to some embodiments of the present disclosure, activated carbon (adsorbent 30 ) is recovered through electrolysis reaction, and the waste liquid (for example, iodine molecules/potassium iodide solution) of the process equipment 1A can be directly used as an electrolyte without being processed again. , and other impurities (such as boric acid) in the waste liquid of the process equipment 1A do not participate in the electrolysis reaction (redox reaction), so other impurities in the waste liquid can be recovered without additional separation or purification. , and then directly recover and reuse the electrolyte as the process liquid of the process equipment 1A, which has the advantages of reducing costs and simplifying the process.

In addition, according to some embodiments of the present disclosure, in addition to the waste liquid from the process equipment 1A (for example, iodine molecules/potassium iodide solution), other electrolytes (for example, zinc sulfate) can be further added to the electrolyte to help electrolysis. To carry out the reaction, the iodine molecules/potassium iodide waste solution and the electrolyte can be purified and recovered simultaneously through electrolysis reaction and/or electrodialysis reaction. The recovered iodine molecules/potassium iodide solution can be put back into the polarizing film production process, and the recovered electrolyte can be put back into the process. During electrolysis reaction.

In some embodiments, the difference between the process liquid 24 and the process liquid 40' is that they have different concentrations. In some embodiments, the concentration of the processing reagent (eg, the optical modifier of the dyeing tank 12 and/or the optical modifier of the cross-linking tank 13 ) in the process liquid 24 and the process liquid 40 ′ is different due to the adsorbent 30 Impurities (eg, processing reagents in the process bath, such as iodine molecules) are ionized, desorbed, and dissolved into the electrolyte 140 , thereby changing the concentration of the process liquid.
