[0022] As a preferred embodiment, on the basis of the above method, further, the filtering and adsorbing assembly 40 includes a rotating shaft 41 rotatably connected to the side wall of the filtering tank 11. A fishing plate 42 is fixedly connected to the side wall of the rotating shaft 41. A filtering and adsorbing plate 43 is clamped to the inner side wall of the fishing plate 42. A guide rail 44 is fixedly installed on the inner side wall of the filtering tank 11. The filtering and adsorbing plate 43 is meshed and connected to the guide rail 44 through a first gear 45. A collecting groove 413 is also fixedly connected to the top of the inner side wall of the filtering tank 11. One end of the rotating shaft 41 passing through the filtering tank 11 is connected to a second gear 46. A power-assisted push rod 47 is also fixedly connected to the side wall of the filtering tank 11. The output end of the power-assisted push rod 47 is fixedly connected to a toothed plate 48. The toothed plate 48 is meshed and connected to the second gear 46. The filtering and adsorbing plate 43 can rotate relative to the fishing plate 42. When it is necessary to move the fishing plate 42, the power-assisted push rod 47 can be telescoped to drive the toothed plate 48 to move. The toothed plate 48 meshes with the second gear 46 to drive the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it can drive the fishing plate 42 to move. When the fishing plate 42 moves, the first gear 45 meshes with the guide rail 44 to drive the filtering and adsorbing plate 43 to rotate, so that the wastewater in the filtering tank 11 rotates, and thus is better adsorbed by the filtering and adsorbing plate 43.

When the servo motor 410 drives the reciprocating lead screw 411 to rotate, the reciprocating lead screw 411 can drive the push plate 412 to move. While the push plate 412 slides horizontally, the impurities in the collecting groove 413 are pushed out.

[0024] A slide bar 414 is also fixedly connected to the top of the cage 49. The slide bar 414 is slidably matched with the push plate 412. The push plate 412 is adapted to the collecting groove 413. The slide bar 414 can maintain the stability of the movement of the push plate 412, so that the push plate 412 can only slide horizontally and will not rotate with the rotation of the reciprocating lead screw 411.

The side wall of the guide rail 44 has a rack adapted to the first gear 45. When the first gear 45 moves to the position of the sliding ball 443, it is restricted by the sliding ball 443. At this time, the first gear 45 cannot rotate.

[0026] One end of the support shaft in the middle of the first gear 45 is slidably connected with a latch 451. A second spring 452 is fixedly connected between the latch 451 and the support shaft. The latch 451 is plugged and clamped with the filter adsorption plate 43. The first support shaft is rotatably connected with the fishing plate 42 through a bearing. When the sliding ball 443 moves, the second spring 452 is compressed. The second spring 452 has elastic potential energy to push the sliding ball 443 to reset in the compressed state, so that the sliding ball 443 is closely attached to the rack position of the guide rail 44.

[0027] As a preferred embodiment, on the basis of the above method, further, the medicine injection component 50 includes a medicine pump 51 fixedly connected to the top of the treatment tank 10. The input end of the medicine pump 51 is communicated with the medicine storage tank 52. The output end of the medicine pump 51 is rotatably connected with the stirring shaft 21 through a sealed bearing. The medicine injection component 50 further includes a hollow sleeve 53 fixedly connected to the side wall of the stirring shaft 21. A telescopic tube 54 is slidably connected to the inner side wall of the hollow sleeve 53. A third spring 55 is fixedly connected between the telescopic tube 54 and the hollow sleeve 53. Corresponding medicine outlet holes 56 are respectively formed in the outer walls of the telescopic tube 54 and the hollow sleeve 53. The medicine injection component 50 further includes a disc track 57 fixedly connected to the inner side wall of the treatment tank 10. A misaligned protrusion 58 is further connected to the inner side wall of the disc track 57. When the stirring shaft 21 rotates, the output end of the medicine pump 51 is rotatably connected with the stirring shaft 21. Therefore, the output end of the medicine pump 51 does not rotate. When the telescopic tube 54 abuts against the misaligned protrusion 58, the misaligned protrusion 58 will push the telescopic tube 54 to fold inward until the telescopic tube 54 is aligned with the medicine outlet hole 56 on the hollow sleeve 53. At this time, the liquid medicine can be discharged, achieving the purpose of automatically injecting the liquid medicine, and the gradual injection of the liquid medicine is convenient for mixing.

[0028] A wastewater treatment method for an integrated treatment device for efficient decolorization and simultaneous COD degradation of printing and dyeing wastewater includes the following operation steps: S1. Open the treatment tank 10, and put the wastewater and the decolorizing agent into the treatment tank 10. S2. Start the driving motor 31, and the driving motor 31 drives the stirring shaft 21 to rotate, so that the stirring blades 22 stir and mix the wastewater and the decolorizing agent. S3. The medicine pump 51 pumps the COD degradation agent inside the medicine storage tank 52 and transports it into the stirring shaft 21. The telescopic tube 54 is aligned with the medicine outlet hole on the hollow sleeve 53 under the extrusion of the misaligned protrusion 58, and then the COD degradation agent can be injected. S4. The water pump pipe group 12 transports the degraded wastewater to the filter box 11, and it is adsorbed and fished by the filter adsorption plate 43.

[0029] Specifically, when the integrated treatment device and method for efficient decolorization of printing and dyeing wastewater and simultaneous degradation of COD are in operation / use: Open the treatment tank 10, put the wastewater and the decolorizing agent into the treatment tank 10, start the driving motor 31, and the driving motor 31 drives the stirring shaft 21 to rotate, so that the stirring blades 22 stir and mix the wastewater and the decolorizing agent. The medicine pump 51 pumps the COD degradation agent inside the medicine storage tank 52 and transports it into the stirring shaft 21. As the stirring shaft 21 rotates, the telescopic pipe 54 is aligned with the medicine outlet hole on the hollow sleeve 53 under the extrusion of the misaligned protrusion 58, and then the COD degradation agent can be injected. After stirring, when the wastewater is effectively treated, the water pump pipe group 12 transports the degraded wastewater into the filtering box 11, and it is adsorbed and fished by the filtering and adsorbing plate 43. Specifically, the electric push rod 47 pushes the toothed plate 48 to move, and the toothed plate 48 meshes with the second gear 46 to drive the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it drives the fishing plate 42 to fish the impurities in the filtering box 11 into the collection tank 413. When the rotating shaft 41 moves, the first gear 45 meshes with the guide rail 44, thereby driving the filtering and adsorbing plate 43 to rotate, so that the filtering and adsorbing plate 43 can perform the adsorption operation better. When the filtering and adsorbing plate 43 needs to be disassembled, the sliding bolt 451 can disassemble the filtering and adsorbing plate 43. At the same time, when the filtering and adsorbing plate 43 needs to be installed, the sliding bolt 451 is inserted. After the bolt 451 is aligned and clamped with the filtering and adsorbing plate 43, it can be used.
