Description

Technical Field

[0001] The invention relates to the technical field of electroplating wastewater treatment, and in particular to an electroplating wastewater treatment device and a method thereof. Background Art

[0002] The wastewater and waste liquid discharged from the electroplating factory contain a large amount of metal ions such as chromium, tin, nickel, cyanide, acid, alkali, and usually organic additives. Some metal ions exist in the form of simple cations, some exist in the form of acid anions, and some exist in the form of complex complex ions. Electroplating wastewater treatment commonly uses chemical methods such as neutralization precipitation, neutralization coagulation precipitation, oxidation, reduction, barium salt, and ferrite. In order to improve the treatment effect of electroplating wastewater, activated carbon adsorption is generally used to remove most of the organic matter and heavy metal ions in the wastewater, and then chemical treatment is used to further remove or transform the remaining harmful substances. Such a comprehensive treatment process can meet the required emission standards.

[0003] According to the Chinese patent with publication number CN114084978A, a new integrated electroplating wastewater treatment device is disclosed.

A rotating drum 506 is movably connected to one side of the partition 101, and an adsorption filler 507 is inlaid and installed at an equal angle on the circumferential side of the rotating drum 506. The adsorption filler 507 is made of activated carbon material. Two spray pipes 8 located below the rotating drum 506 are also inserted in the middle of the upper box body 1; Two drainage plates 401 are symmetrically installed on the upper side of the inner wall of the bottom box 3. The bottom end of the drainage plate 401 is connected to an elastic strip 402. The drainage plate 401 is inclined, and the elastic strip 402 is made of an elastic material not limited to rubber. A separation tank 404 for filtering sediment is fixed at the bottom of the adjacent side of the two drainage plates 401. A spray pipe 403 is arranged in the middle of the separation tank 404. Spray nozzles are equidistantly arranged on the outer peripheral side of the spray pipe 403. One end of the spray pipe 403 is inclined. The center of the upper box 1 is butted with a connecting pipe 405, and one end of the connecting pipe 405 extending through the bottom box 3 is connected to a rotating joint 406. The opening on the upper side of the bottom box 3 is equidistantly provided with inclined plates 301, the outer wall surface of the cone bucket 502 is provided with a gear ring 503, and the inner wall surface of the upper box body 1 is provided with a transmission gear plate 408 meshing with the gear ring 503. The outer side of the connecting pipe 405 and the central axis end of the transmission gear plate 408 are sleeved with synchronous wheels, and a synchronous belt 407 is sleeved between the two synchronous wheels; A medicine box 9 is provided on one side of the bottom box 3 away from the rotary joint 406. The medicine box 9 is respectively connected to the spray pipe 8 and the rotary joint 406 through an internal metering pump. A discharge pipe 10 for cleaning the sediment inside the separation tank 404 is connected to the side of the upper box body 1 close to the medicine box 9. A control valve for controlling the opening and closing is connected to the discharge pipe 10. By adding cleaning liquid to the primary filter tank 2 and opening the control valve on the discharge pipe 10, the cleaning liquid is driven by the pump body 203 to be sent into the drum 506. After that, the cleaning liquid enters the bottom box 3 and carries the precipitated impurities in the separation tank 404 out along the discharge pipe 10, so as to facilitate the cleaning of the precipitated impurities generated by the electroplating wastewater treatment. A motor 505 is installed on the outer side of the upper box body 1. The output end of the motor 505 inserted into the upper box body 1 is connected to a driving gear 504, and the driving gear 504 is meshed with the gear ring 503. A through hole is provided on the lower side of one end of the cannula 501 extending into the drum 506. By providing a through hole on the surface of the cannula 501, it is convenient for wastewater to enter the cannula 501 along the conduit 202, and then the wastewater enters the drum 506 through the through hole of the cannula 501, so that the wastewater can be directly sent to the drum 506 for adsorption treatment; One side of the primary filter tank 2 is connected to a water inlet, one side of the bottom box 3 is connected to a drain outlet, and a grid 201 for removing impurities in wastewater is installed in the middle of the primary filter tank 2.

[0020] In the specific implementation, the electroplating wastewater produced by the industrial production enters the primary filter tank 2 through the water inlet, and the impurities are intercepted and filtered by the grille 201 in the primary filter tank 2, and the filtered wastewater enters the conduit 202, and at the same time, the pump body 203 on the conduit 202 drives the wastewater along the cannula 501 to be sent into the rotating drum 506; when the motor 505 drives the driving gear 504 to rotate forward, the driving gear 504 will mesh with the toothed ring 503 on the outer side of the cone bucket 502, so that the cone bucket 502 drives the rotating drum 506. The drum 506 rotates in the opposite direction. When the drum 506 rotates in the reverse direction, it will drive the adsorption fillers 507 distributed at equal angles to rotate synchronously. The rotating adsorption fillers 507 will throw the wastewater in the drum 506 into the bottom box 3, and the adsorption fillers 507 will adsorb and remove most of the organic matter and heavy metal ions in the wastewater. By rotating the adsorption fillers 507 by the drum 506, several adsorption fillers 507 can be alternately inserted into the wastewater for adsorption treatment, ensuring that the adsorption fillers 507 can continuously and efficiently adsorb and treat the wastewater; When the rotating adsorption filler 507 throws the wastewater in the drum 506 into the bottom box 3, the metering pump in the medicine box 9 pressurizes the agent and transports it into the spray pipe 8, and then the agent is sprayed obliquely into the bottom box 3 through the spray pipe 8. When the agent is sprayed onto the inclined plate 301, the inclined plate 301 will cause the agent to recoil upward, so that the agent impacts the drum 506 from the inclined plate 301, so that the water thrown downward by the adsorption filler 507 is oscillated and mixed with the agent, thereby accelerating the mixing efficiency, and the wastewater and the agent are mixed. When the mixed liquid is generated, it will fall into the bottom box 3 along the inclined plate 301; at the same time, the reversed gear ring 503 will mesh with the transmission gear plate 408, so that the transmission gear plate 408 drives the synchronous belt 407 to rotate forward through the synchronous wheel, and then drives the synchronous wheel on the connecting pipe 405 to rotate forward through the synchronous belt 407, so that the connecting pipe 405 drives the eccentrically connected injection pipe 403 to rotate forward between the two elastic strips 402, and when the medicine in the medicine box 9 is fed into the injection pipe 403 through the rotary joint 406, the injection When the tube 403 rotates and swings in the positive direction, it will drive the nozzle to swing and spray the medicine, so that the medicine will be mixed and contacted with the mixed liquid falling into the bottom box 3 from bottom to top for a second time. At the same time, when the injection tube 403 rotates and swings eccentrically, it will produce an intermittent movement of extrusion contact and deflection separation with the elastic strip 402. When the injection tube 403 is in extrusion contact with the elastic strip 402, the mixed liquid will accumulate on the upper side of the guide plate 401 for chemical reaction. When the injection tube 403 is in deflection separation of the elastic strip 402, the mixed liquid will flow along the injection tube 403 and the gap between the elastic strip 402 enters the separation tank 404; then the rotating injection tube 403 will also spray the reagent into the separation tank 404, so that the mixed liquid reacts with the reagent three times in the separation tank 404, so that the electroplating wastewater can achieve sufficient chemical reaction in the bottom box 3 to change the physical and chemical properties of the pollutants in the wastewater, and the separation tank 404 can filter the precipitate transformed from the pollutants. Finally, the wastewater that has completed the reaction with the chemical reagent is discharged outward through the drain port on the side of the bottom box 3.

[0021] See also Figure 3 , Figure 9-12 An activation mechanism 6 is provided on the upper side of the insert tube 501 near one end of the through hole, and the activation mechanism 6 includes a mounting seat 601 docked on the upper side of the insert tube 501, the top of the mounting seat 601 is set as an arc surface, a groove is provided in the middle of the arc surface of the mounting seat 601, and a card groove 602 is provided in the middle of the groove, and docking channels 603 connected with the groove are provided on both side edges of the mounting seat 601; A spring 604 is connected to the inner wall of the groove of the mounting seat 601, and an extrusion piece 605 is slidably connected to the side of the groove close to the docking channel 603. The surface of the extrusion piece 605 is provided with a U-shaped inner cavity, and the inner wall of one side of the U-shaped inner cavity is provided with equidistantly distributed protrusions; an arc-shaped blowing pipe 606 is provided between the spring 604 and the extrusion piece 605, and the outer arc surface of the arc-shaped blowing pipe 606 is provided with equidistantly distributed blowing ports; A horizontal tube that docks with the slot 602 is fixed at the bottom of the arc-shaped blowing tube 606, and a bellows 607 is connected to the lower side of the middle of the horizontal tube. When the arc-shaped blowing tube 606 moves back and forth, the bellows 607 is stretched back and forth to facilitate the continuous introduction of hot air into the arc-shaped blowing tube 606. A positioning pin 608 is connected to the outer peripheral side wall of the rotating cylinder 506 near the cone bucket 502, and a ball is movably connected to one end of the positioning pin 608. An air inlet pipe 609 is connected to the lower side of the mounting seat 601, and the air inlet pipe 609 is connected to the bottom end of the bellows 607. The air inlet pipe 609 is movably connected to the rotating drum 506 via a sealed bearing. One end of the air inlet pipe 609 extends through the upper box body 1, and an electric heater 7 connected to the air inlet pipe 609 is installed on the outer side of the upper box body 1, and a blower fan is installed on the surface of the electric heater 7.

[0022] In a specific implementation, when the cone bucket 502 drives the rotating drum 506 to rotate on one side of the partition 101, the rotating drum 506 will drive the adsorption filler 507 to rotate and adjust its position. When the adsorption filler 507 rotates upward and approaches the mounting seat 601, the positioning pin 608 installed on the rotating drum 506 will enter the U-shaped inner cavity of the extrusion member 605 along the docking channel 603 at the edge of the mounting seat 601, and when the positioning pin 608 continues to rotate with the rotating drum 506, the positioning pin 608 will intermittently squeeze the protrusion of the inner wall of the extrusion member 605 through the ball at one end, so that the extrusion member 605 and the arc-shaped blowing pipe 606 can slide back and forth along the groove with the assistance of the spring 604, and the arc-shaped blowing pipe 606 can be sprayed. The horizontal tube on the lower surface of the tube 606 will slide along the slot 602. When the electric heater 7 and the blower fan are started, the blower fan will send air to the electric heater 7 for heating, and the hot air will be introduced into the equally spaced arc-shaped blowing tube 606 along the air inlet pipe 609 and the bellows 607. When the arc-shaped blowing tube 606 moves back and forth, the blowing port on the outer arc surface will efficiently blow and heat the adsorption filler 507 rotating through the mounting seat 601, so that the adsorption filler 507 is activated and regenerated under the action of heating, ensuring that the adsorption filler 507 can be activated and regenerated without stopping when rotating with the drum 506, thereby ensuring that the adsorption filler 507 has sufficient efficiency in the adsorption treatment of electroplating wastewater.

[0023] A method for treating electroplating wastewater comprises the following steps: S1, preliminarily filtering and removing impurities from the electroplating wastewater through the pre-filter tank 2, thereby removing large particles of impurities in the electroplating wastewater, and the efficiency of filtering and removing impurities can be ensured by regularly cleaning the grid 201 in the pre-filter tank 2; S2. The electroplating wastewater is continuously adsorbed by the adsorption filler 507 that continuously rotates in the upper box 1. When the adsorption filler 507 with equal angles rotates with the drum 506, the adsorption filler 507 can adsorb and treat the wastewater when it rotates to the lower side of the drum 506. When the adsorption filler 507 rotates to the upper side of the drum 506, it can be activated and regenerated by heating through the activation mechanism 6. S3. The wastewater after adsorption treatment undergoes sufficient chemical reaction with the chemical agents sprayed from the spray pipe 8 and the dosing reaction mechanism 4, respectively, so that the mixed liquid in the chemical reaction process can precipitate impurities.
