[0002] The environmental protection type electroplating wastewater recycling treatment system is a system specially used for treating wastewater generated in the electroplating industry and realizing wastewater recycling. The main purpose of this system is to reduce environmental pollution and reduce water costs for enterprises.
[0003] A Chinese utility model patent discloses a wastewater recycling treatment system, which includes a wastewater providing device, at least one adsorption device, and a recycling device. The wastewater providing device is used to provide wastewater. The at least one adsorption device is configured to receive wastewater through a first pipeline, adsorb a certain amount of treated substances from the wastewater, and discharge the adsorbed wastewater through a second pipeline. The recycling device is configured to return the adsorbed wastewater to the at least one adsorption device. Thus, the utility model improves the efficiency of the wastewater treatment device.
[0004] Traditional electroplating wastewater treatment methods such as chemical precipitation and oxidation-reduction often require a large amount of chemical reagents and energy, resulting in high treatment costs. The sludge and waste liquid generated during wastewater treatment also need to be specially treated and disposed, further increasing the cost. Traditional methods often cannot completely remove heavy metal ions and organic pollutants in water during the treatment of electroplating wastewater, resulting in a certain risk in the quality of treated water. Especially for some high-concentration or difficult-to-degrade pollutants, the treatment effect of traditional methods is more limited. During the wastewater treatment process, if the treatment is not proper or the equipment is aging, etc., secondary pollution such as heavy metal leachate in sludge is easily produced. If these secondary pollutants are not properly treated, they may cause greater harm to the environment. Some electroplating wastewater treatment facilities have low automation, and manual monitoring and operation are required, which not only increases labor costs but also easily leads to poor treatment effect due to human operation errors. Therefore, an environmental protection type electroplating wastewater recycling treatment system is needed to solve the above problems. SUMMARY

[0025] Specifically, the end of the connecting pipe 7 furthest from the primary filter box 8 is fixedly connected to the inlet end of the sedimentation tank 6, and a sealing ring is provided at the connection outlet between the connecting pipe 7 and the inlet end of the sedimentation tank 6, and the connecting pipe 7 is connected to the inlet end of the sedimentation tank 6.
[0026] Specifically, the multiple guide plates 15 are arranged symmetrically in a cross pattern. The side of each guide plate 15 away from the inner wall of the secondary filter box 17 is not connected to the symmetrical inner wall of the secondary filter box 17, so that the secondary filter box 17 and the guide plates 15 form an opening. The openings are staggered from top to bottom, so that the secondary filter box 17 and the guide plates 15 form an S-shaped channel, which increases the travel distance of the water flow inside the secondary filter box 17 and increases the residence time of the water flow inside the secondary filter box 17. The front and rear ends of the multiple guide plates 15 are fixedly connected to the front and rear end walls of the secondary filter box 17, respectively, and the connection between the guide plates 15 and the secondary filter box 17 is provided with sealant.
[0027] Specifically, the top of the secondary filter box 17 is provided with a sealing cover 12, the bottom of the sealing cover 12 is tightly attached to the top of the filter structure 13, and a sealing ring is provided at the connection between the sealing cover 12 and the filter structure 13, and a sealing gasket is provided at the connection between the filter structure 13 and the placement rack 14.
[0028] Specifically, the cleaning mechanism 1, the first water pump 4, the sedimentation tank 6, the primary filter box 8, the control box 10, the secondary filter box 17, the second water pump 20, and their accessories constitute an environmentally friendly electroplating wastewater recycling system.
[0029] In use, when using this electroplating wastewater treatment system, the wastewater first flows smoothly into the drain pipe 9 through the drain end of the cleaning mechanism 1. This drain pipe 9 serves as the initial guiding channel for the wastewater, ensuring that it can enter the primary filter box 8 without obstruction. Inside the primary filter box 8, the wastewater undergoes rapid and effective preliminary filtration through the built-in filtration device, removing most of the larger impurities and particles. The water after primary filtration becomes relatively clear and is then smoothly introduced into the sedimentation tank 6 through the connecting pipe 7. In the sedimentation tank 6, the water undergoes a period of settling, which helps to further remove suspended solids and sediments, further improving the water quality. When the sedimentation process is complete... After completion, by turning on the first water pump 4, the settled water is forcefully pumped out and flows into the outlet pipe 11 through the second outlet 5. This pipe acts as a bridge connecting the primary filter box 8 and the first water pump 4, ensuring that the water flow can continuously and stably enter the inlet of the first water pump 4. Subsequently, under the powerful force of the first water pump 4, the water is rapidly drawn in and pressurized, and then sent into the secondary filter box 17 through the fixed pipe 18. Inside the secondary filter box 17, the water undergoes a more complex and refined treatment process. The water flows slowly along a complex and tortuous S-shaped channel formed by the secondary filter box 17 and multiple carefully designed guide plates 15. This unique design not only greatly increases the efficiency of the secondary filter box 8 but also enhances the water quality of the secondary filter box 8. This design not only shortens the water flow path within the secondary filtration box 17 but also significantly extends the water's residence time within the box. This undoubtedly provides ample time for subsequent filtration and sterilization processes, allowing for more thorough water purification. As the water flows along the S-shaped channel, the ultraviolet sterilizer 16 mounted on the guide plate 15 emits intense ultraviolet rays. These ultraviolet rays act like invisible swords, comprehensively sterilizing the water within the channel. They penetrate deep into the water flow, effectively destroying the DNA structure of bacteria, viruses, and other microorganisms, thereby completely eliminating these potential sources of contamination. After treatment by the ultraviolet sterilizer 16, the water continues to flow along the S-shaped channel until it reaches... The water reaches the inner top wall of the secondary filtration box 17; here, the filter structure 13 can further remove tiny particles and impurities from the water; after this round of filtration, the water quality has become exceptionally fresh and pure; finally, the water after secondary filtration is pumped back into the installation pipe 19 by the second water pump 20; under the powerful force of the second water pump 20, this strictly treated water will smoothly pass through the inlet pipe 3 and flow back into the cleaning mechanism 1; at this point, the entire water treatment process is successfully completed, and the cleaning mechanism 1 can continue to use this purified water for subsequent cleaning work; such recycling not only improves the efficiency of water resource utilization, but also helps to protect the environment and achieve sustainable development.In summary, this environmentally friendly electroplating wastewater recycling system, through the installation of a sealing cover 12, a filter box, a placement rack 14, a flow guide plate 15, an ultraviolet sterilizer 16, and a secondary filter box 17, ensures the airtightness of the secondary filter box 17, effectively preventing water leakage and the entry of external pollutants during the treatment process, thereby guaranteeing the purity of the water and the stable operation of the system. The combined use of the filter structure 13 and the placement rack 14 enables the filter material to stably and efficiently remove small particles and impurities from the water, further improving the clarity and purity of the water. At the same time, the easy replacement of the filter structure 13 facilitates the maintenance and upkeep of the system. The placement of the flow guide plate 15 causes the water flow to form a complex and tortuous S-shape within the secondary filter box 17. The channel not only increases the water flow path but also significantly extends the water's residence time within the tank. This design helps suspended solids and pollutants in the water to settle and filter more thoroughly, thereby improving the system's treatment efficiency. The ultraviolet sterilizer 16 provides comprehensive sterilization of the water within the channel, effectively destroying the DNA structure of bacteria, viruses, and other microorganisms, thus completely eliminating these potential sources of pollution. This not only improves the hygiene standards of the water quality but also ensures the safety and reliability of the system. Through the system's cyclical treatment, electroplating wastewater can be effectively purified and reused, thereby reducing the consumption of fresh water resources and wastewater discharge. This not only helps protect water resources and the ecological environment but also achieves the sustainable development of the electroplating industry.
