[0022] As shown in the accompanying Figure 1 to the accompanying Figure 3 As shown:

[0023] The utility model provides a kind of synthetic leather sewage treatment equipment, including flocculation sedimentation tank 1, discharge port 2, water inlet 3, guide beam 4, flocculation combination box 5, flocculation forming channel 6, high-frequency static generator 7, extract flocculation pump 8 and flocculation well 9, flocculation sedimentation tank 1 and flocculation tank are mutually arranged together, the water inlet 3 of flocculation sedimentation tank 1 is connected with flocculation tank, and flocculation sedimentation tank 1 is arranged discharge port 2 and downstream stage pool is connected with;The guide beam 4 of fixed installation in the inside upper portion of flocculation sedimentation tank 1 is located the upper portion of flocculation combination box 5 installed in its inside, and a plurality of flocculation forming channels 6 are arranged in the upper portion of flocculation combination box 5;The flocculation well 9 of being arranged in the inside center of flocculation sedimentation tank 1 is connected with extract flocculation pump 8 by pipeline, and extract flocculation pump 8 and high-frequency static generator 7 are fixedly installed in the outside of flocculation sedimentation tank 1.

[0024] Further, discharge port 2 is ingeniously arranged on the upper side of the main body 11 of flocculation sedimentation tank 1, and is located on the side of several transversely arranged guide beams 4. Such design helps to optimize the water flow path, ensuring that the treated water can be smoothly discharged. At the same time, the water inlet 3 is arranged at the middle-lower position of the side of the main body 11 of flocculation sedimentation tank 1, facilitating the introduction of sewage.

[0025] Further, the guide beams 4 are transversely distributed on the inside upper portion of the main body 11, playing a role in guiding water flow and enhancing flocculation effect. On the outside of the main body 11, the extract flocculation pump 8 and the high-frequency static generator 7 are fixedly installed, and the two work cooperatively, improving the processing efficiency of the equipment. In addition, the flocculation well 9 is also arranged at the lower center of the inside of the main body 11, for collecting and discharging flocculation.

[0026] Further, the flocculation sedimentation tank 1 includes the main body 11, the bottom support plate 12, the gland plate 13 and the through hole 14, the bottom support plate 12 is fixedly installed on the inside upper portion of the main body 11, and the flocculation combination box 5 is arranged on the upper portion. The flocculation combination box 5 is fixed by the upper gland plate 13. A plurality of through holes 14 are formed in the bottom support plate 12 and the gland plate 13, and these through holes 14 allow liquid to enter and exit the flocculation forming channel 6.

[0027] Further, the flocculation combination box 5 on the inside upper portion of the main body 11 is provided with a serpentine-shaped flocculation forming channel 6. The upper and lower ends of these channels correspond to the through holes 14 of the bottom support plate 12 and the gland plate 13, respectively, ensuring that the sewage can smoothly enter and flow through the flocculation forming channel 6, thereby realizing the further growth and stability of the flocculation.

[0028] Further, below the coagulation and flocculation box 5, i.e. below the inner side of the water inlet 3, a plurality of electrostatic emission plates 15 are arranged transversely. These electrostatic emission plates 15 are connected to the high-frequency electrostatic generator 7 fixedly installed outside the main body 11. The electrostatic emission plates 15 have a spacing between each other, and the spacing forms an electrostatic field channel. The transversely arranged electrostatic emission plates 15 are located above the flocculation well 9, and they can adsorb small flocculation materials with opposite charges to themselves and repel small flocculation materials with the same charges as themselves, thereby improving the recycling rate of flocculation materials.

[0029] Further, the transversely arranged electrostatic emission plates 15 are divided into positive plates and negative plates, and they are arranged in an alternating manner. This means that the electrostatic charges generated by two adjacent electrostatic emission plates 15 are opposite. Such a design helps to form a stronger electric field gradient in the electrostatic field channel, thereby more effectively adsorbing and repelling flocculation materials.

[0030] The working principle is as follows: First, the liquid in the flocculation tank enters the main body 11 of the coagulation and flocculation tank 1 through the water inlet 3. As the liquid flows in, it begins to flow upwards, and in this process, the liquid first passes through the evenly distributed through holes 14 on the bottom support plate 12. These through holes 14 are designed just right, allowing the liquid to smoothly enter the flocculation forming channel 6 provided in the coagulation and flocculation box 5.

[0031] Once it enters the flocculation forming channel 6, the suspended solids and organic matter in the sewage begin their flocculation process. The flocculation forming channel 6 adopts a serpentine design, which not only prolongs the residence time of the flocculation materials, but also increases their chances of colliding with each other. In such an environment, suspended solids and organic matter can more fully combine with coagulants to form flocculation materials of varying sizes.

[0032] As the flocculation process proceeds, small and large flocculation materials begin to fall downward. At this time, they will encounter the electrostatic emission plates 15 transversely arranged below the coagulation and flocculation box 5. These electrostatic emission plates 15 are powered by the high-frequency electrostatic generator 7 and are divided into positive plates and negative plates, arranged in an alternating manner. Therefore, the electrostatic charges generated by adjacent electrostatic emission plates 15 are opposite, thereby forming an electrostatic field channel between them.

[0033] When the flocculation materials pass through the electrostatic field channel, small flocculation materials with opposite charges to the electrostatic emission plates will be firmly grasped by the electrostatic adsorption force, while flocculation materials with the same charges will be repelled. Such a mechanism not only effectively reduces the loss of flocculation materials, but also significantly improves the recycling rate of flocculation materials.

[0034] Finally, the flocculation after electrostatic treatment will continue to fall, until falling into the flocculation well 9 located in the inside center below the flocculation sedimentation tank 1. The flocculation well 9 is connected with the flocculation pump 8 through the pipeline, and the flocculation pump 8 will be started regularly, and the accumulated flocculation is pumped out and sent to the subsequent processing stage.

[0035] At the same time, the clear water after flocculation sedimentation and electrostatic treatment will continue to flow upward, and finally be smoothly discharged through the discharge port 2 arranged on the upper side of the main body 11 of the flocculation sedimentation tank 1, and enter the downstream stage tank for further treatment or utilization.

[0036] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, and the similar technical scheme achieving the above technical effects all fall within the protection scope of the utility model.
