In order to ensure beauty and effect, electroless nickel plating is sometimes used, and complexing agents such as citric acid, EDTA, tartaric acid, and malic acid are used. With the improvement of environmental protection emission standards, some regions require zero emissions of heavy metals such as nickel, which increases the treatment difficulty and cost of nickel-containing wastewater.

[0003] For example, the Chinese utility model patent with the publication number CN219907283U relates to the technical field of wastewater treatment and discloses a nickel-containing wastewater discharge device, including a discharge treatment device. The discharge treatment device includes: a collection tank, one side of which is connected to an MCR reaction tank, and a PH adjustment device is arranged on the MCR reaction tank; a primary RO raw water tank is arranged on one side of the MCR reaction tank and is connected to the MCR reaction tank; a primary RO system is arranged on one side of the primary RO raw water tank and is connected to the primary RO raw water tank; a primary RO product water tank is arranged on one side of the primary RO system and is connected to the primary RO system. This nickel-containing wastewater discharge device avoids the disadvantages of the conventional coagulation and sedimentation process relying on a large amount of chemical dosing through pretreatment, reduces the dosing of coagulant aids and flocculants in the physico-chemical reaction section, reduces the dependence on coagulants and flocculants, and also reduces the pollution risk of the subsequent process membrane concentrate water system, realizing zero discharge of nickel-containing wastewater, with strong applicability, high treatment efficiency, and stable performance.

[0004] When treating nickel-containing wastewater, large wastewater treatment equipment is usually used. These devices treat wastewater through a series of complex technological processes. Although the quality of wastewater treatment can be guaranteed, the equipment occupies a large area, has a complex operation process, and is large in volume and not easy to move, which is inconvenient.

[0011] By adopting this technical solution, through the arranged connecting pipes and water pump, the wastewater can sequentially pass through the wastewater collection tank, the pretreatment tank, the wastewater treatment component and the UV disinfection device, thus completing the treatment of the wastewater.

[0012] Furthermore, the wastewater treatment component includes mounting blocks, mounting frames and a plurality of treatment cylinders.

Specific implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1 , in this embodiment, a super-small integrated nickel-containing wastewater zero-emission device includes a wastewater collection tank 1. The inner bottom wall of the wastewater collection tank 1 is provided with an inclined surface. A pretreatment tank 2 is fixed on the right side of the wastewater collection tank 1. A limiting plate 3 is fixed inside the pretreatment tank 2. The limiting plate 3 is a hollow annular plate. A filter screen 4 located on the top of the limiting plate 3 is slidably connected inside the pretreatment tank 2. The provided limiting plate 3 is used to prevent the filter screen 4 from moving downwards excessively. Sliding blocks 15 are fixed on both the left and right sides of the filter screen 4. Sliding grooves slidably connected to the sliding blocks 15 are formed inside the pretreatment tank 2. By providing the sliding blocks 15 and the sliding grooves, the position of the filter screen 4 can be positioned, and the filter screen 4 can move more stably when moving, thereby making the whole more practical.

[0032] In addition, two support blocks 5 are fixed to the top of the filter net 4 and penetrate through the top of the pretreatment tank 2. A sponge pad is fixed to the top of the support block 5, and the sponge pad is in contact with the cover plate 601. A fixing component 6 is arranged on the top of the pretreatment tank 2, and the fixing component 6 is used to fix the filter net 4. A wastewater treatment component is fixed to the right side of the pretreatment tank 2, and the wastewater treatment component is used to treat the nickel-containing wastewater. The wastewater treatment component includes a mounting block 8, a mounting frame 9, and a plurality of treatment cylinders 7. The ultraviolet disinfection device 11 is fixed to the treatment cylinder 7 between the ultraviolet disinfection device 11 and the pretreatment tank 2. The outer surface of the treatment cylinder 7 is fixed to the mounting block 8, and the upper and lower sides of the mounting block 8 are fixed to the mounting frame 9. The inside of the treatment cylinder 7 is filled with ion exchange resin and modified activated carbon, so that when the wastewater passes through the treatment cylinder 7, the nickel ions in the wastewater can be adsorbed, thereby effectively improving the wastewater treatment efficiency. A ultraviolet disinfection device 11 is fixed to the right side of the wastewater treatment component, and a storage tank 10 is fixed to the right side of the ultraviolet disinfection device 11.

[0033] It should be noted that a connecting pipe 12 is fixed between the wastewater collection tank 1, the pretreatment tank 2, the wastewater treatment component, the ultraviolet disinfection device 11, and the storage tank 10. A water pump 13 is fixed inside the connecting pipe 12. By setting the connecting pipe 12 and the water pump 13, the wastewater can pass through the wastewater collection tank 1, the pretreatment tank 2, the wastewater treatment component, and the ultraviolet disinfection device 11 in sequence, thereby completing the treatment of the wastewater.

[0034] Generally speaking, by setting the pretreatment tank 2 and the filter net 4, the fine impurities in the wastewater can be filtered. By setting the treatment cylinder 7, the nickel ions in the wastewater can be adsorbed, and finally, by setting the ultraviolet disinfection device 11, the wastewater can be disinfected, thereby completing the treatment of the wastewater.

[0035] Please refer to Figures 2 to 3The fixing assembly 6 in this embodiment includes a cover plate 601, a fixing block 602, a fixing rod 603, a moving block 604 and a limiting block 605. The top of the pretreatment box 2 is fixed to the cover plate 601, and a positioning block 14 is fixed to the bottom of the cover plate 601. A positioning groove adapted to the positioning block 14 is provided on the top of the pretreatment box 2. The positioning block 14 and the positioning groove are provided so that the position between the cover plate 601 and the pretreatment box 2 can be more accurate. The left and right sides of the pretreatment box 2 are fixed to the fixing block 602, and the bottom of the cover plate 601 is fixed to the fixing rod 603 that passes through the fixing block 602. The outer surface of the fixing rod 603 is threadedly connected to the moving block 604, and the fixing rod 603 is an external screw. The movable block 604 has a threaded hole inside that matches the external threaded rod. The external threaded rod allows the movable block 604 to move simultaneously due to the extrusion of the thread when it rotates. The outer surface of the movable block 604 is fixed to the limit block 605. The fixed block 602 has a mounting hole 606 inside that matches the movable block 604. The fixed block 602 has a positioning hole 607 inside that is connected to the mounting hole 606. The positioning hole 607 matches the limit block 605. The movable block 604 can be moved to the bottom of the fixed block 602 through the mounting hole 606, and the positioning hole 607 allows the limit block 605 to pass through the fixed block 602.

[0036] In general, by setting the mounting hole 606 and the positioning hole 607, the limit block 605 and the movable block 604 can be moved to the bottom of the fixed block 602. When the movable block 604 rotates, the limit block 605 and the positioning hole 607 are offset, and the limit block 605 moves toward the fixed block 602, so that the cover plate 601 and the pretreatment box 2 are more tightly connected.

[0037] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0038] The working principle of the above embodiment is:

[0039] Under the traction of the water pump 13 and the connecting pipe 12, the wastewater inside the wastewater collection tank 1 will flow into the inside of the pretreatment tank 2. Under the action of gravity, the wastewater will flow downward and pass through the filter screen 4, enabling the filter screen 4 to filter out the fine impurities in the wastewater. When the wastewater flows into the inside of the treatment cylinder 7 through the connecting pipe 12, the ion exchange resin and modified activated carbon filled inside the treatment cylinder 7 will adsorb the nickel ions in the wastewater, thus completing the preliminary treatment of the wastewater. Finally, through the provided ultraviolet disinfection device 11, the treated wastewater can be disinfected, making the recycled water meet the safety standards. When it is necessary to clean the filter screen 4, by pushing the limit block 605, the moving block 604 rotates on the outer surface of the fixed rod 603, so that the limit block 605 rotates to coincide with the positioning hole 607. At this time, it is convenient to pull up the cover plate 601 to complete the disassembly of the fixing component 6. Since the cover plate 601 loses the extrusion on the support block 5, it is convenient to pull up the support block 5 at this time to complete the disassembly of the filter screen 4. The overall structure is simple, reducing the floor area and volume of the equipment, making the whole easy to move.
