The top of the filter screen 4 is fixedly connected to a lifting rod 41, and the left and right sides of the top of the inner ring frame 3 are fixedly connected to a lifting frame 5. A lifting mechanism is provided in the lifting frame 5, and the lifting mechanism controls the lifting of the filter screen 4 by being movably connected to the lifting rod 41. A stirring mechanism 6 is provided at the bottom of the filter screen 4.

[0028] By setting up the rotating mechanism, filter screen 4, lifting mechanism and stirring mechanism 6, the filter screen 4 and the stirring mechanism 6 below the filter screen 4 are driven to rotate by the rotating mechanism, so that the added reagent can be completely dissolved and stirred evenly, and fully react with the electroplating wastewater; when the reaction generates large particle precipitation, the height of the filter screen 4 is adjusted by the upgrading mechanism, so that the supernatant is located above the filter screen 4 and the precipitation is located below the filter screen 4, and the floating impurities are blocked by the filter screen 4, so that the supernatant needs to be filtered through the filter screen 4 before being discharged to the next process, and the quality of the supernatant is guaranteed. When the precipitation needs to be discharged, the stirring mechanism 6 is driven to rotate by the rotating mechanism to facilitate discharge. After a period of use, when a certain amount of impurities accumulate on the filter screen 4, the filter screen 4 can be easily lifted up for cleaning by the upgrading mechanism.

[0029] In addition, in this embodiment, the lifting mechanism includes a vertical screw 51 and a servo motor 52. Support plates 53 are provided at the upper and lower ends of the lifting frame 5. The two ends of the vertical screw 51 are rotatably connected between the two support plates 53 through bearings. The top surface of the upper support plate 53 is fixed with a servo motor 52. The servo motor 52 drives the vertical screw 51 to rotate. The outer sides of the two lifting rods 41 are fixedly connected with lifting blocks 411, and the lifting blocks 411 are threadedly connected to the vertical screw 51.

[0030] Start the servo motor 52, which drives the vertical screw 51 to rotate, so that the lifting block 411 threadedly connected to the vertical screw 51 moves up and down, thereby driving the lifting rod 41 fixedly connected to the lifting block 411 to move up and down, and then driving the filter screen 4 at the bottom end of the upgrading rod 41 to move up and down.

[0031] In addition, in this embodiment, the stirring mechanism 6 includes an L-shaped stirring plate 61 and a telescopic rod 62, the top of the L-shaped stirring plate 61 is fixedly connected to one end of the telescopic rod 62, and the other end of the telescopic rod 62 is fixedly connected to one side of the bottom end of the filter screen 4. A spring 63 is provided on the outer surface of the telescopic rod 62, one end of the spring 63 is fixedly connected to the L-shaped stirring plate 61, and the other end of the spring 63 is fixedly connected to the bottom end of the filter screen 4. A scraper plate 64 is fixedly connected to one side of the L-shaped stirring plate 61, and the scraper plate 64 is in contact with the inner wall side and bottom surface of the sedimentation tank body 1. The stirring mechanism 6 is provided with four groups, and the four groups of stirring mechanisms 6 are evenly arranged on the four sides of the front, back, left and right of the bottom end of the filter screen 4.

[0032] The stirring mechanism 6 is arranged at the lower end of the filter screen 4, and can keep up with the up and down movement and rotation of the filter screen 4. Through the telescopic rod 62 and the spring 63, the distance between the L-shaped stirring plate 61 and the bottom of the sedimentation tank body 1 can be adjusted by the telescopic rod 62 as needed to ensure that the scraper plate 64 is in contact with the bottom surface of the sedimentation tank body 1, so that the sludge accumulated at the bottom and sides of the sedimentation tank body 1 that cannot be discharged can be scraped off.

[0033] Moreover, in this embodiment, a mud discharge pipe 7 is installed at the bottom of the sedimentation tank body 1. The mud discharge pipe 7 is L-shaped, and a mud discharge motor 71 is installed at one end of the mud discharge pipe 7. A spiral mud discharge blade 72 is installed at the output end of the mud discharge motor 71 and located inside the mud discharge pipe 7. The spiral mud discharge blade 72 is rotatably connected to the mud discharge pipe 7. A mud discharge hole 73 is opened at one end of the bottom of the mud discharge pipe 7. An installation groove 74 is provided at the middle end of the bottom of the mud discharge pipe 73. A filter screen 75 is fixedly connected to the installation groove 74. A water collecting tank 76 is provided below the mud discharge pipe 7 and directly below the filter screen 75.

[0034] When mud discharge is required, the generated sediment can be discharged from the mud discharge pipe 7 and slide down to the mud discharge pipe 7. The mud discharge motor 7 is started to drive the spiral mud discharge blades 72 to rotate, so that the sediment is discharged through the spiral mud discharge blades 72. The water generated in the process of the sediment being transported and squeezed by the spiral mud discharge blades 72 falls into the water collection tank 76 through the filter screen 75 and is then transported back for reprocessing, which prevents environmental pollution and also reduces the weight of the sediment.

[0035] When the electroplating wastewater is treated in the coagulation reaction sedimentation tank, reagents are added to make heavy metal ions react with it to generate precipitates, and the rotating motor 2 is started. The rotating motor 2 drives the transmission gear 21 to rotate, and the transmission gear 21 is meshed with the transmission gear 31, so that the inner ring frame 3 rotates, and the rotation of the inner ring frame 3 drives the lifting frame 5 to rotate, and the rotation of the lifting frame 5 drives the filter screen 4 to rotate. The rotation of the filter screen 4 and the L-shaped stirring plate 61 at its lower end can make the reagents stirred evenly, completely dissolved, and fully react with the electroplating wastewater; when the reaction generates large particles of precipitation, the height of the filter screen 4 is adjusted by the upgrading mechanism so that the supernatant is located above the filter screen 4 and the precipitate is located below the filter screen 4. The floating impurities are blocked by the filter screen 4, so that the supernatant The sludge needs to be filtered through the filter screen 4 before being discharged to the next process, and the quality of the supernatant is guaranteed; when sludge needs to be discharged, the rotating mechanism drives the stirring mechanism 6 to rotate to facilitate discharge. The distance between the L-shaped stirring plate 61 and the bottom of the sedimentation tank body 1 can be adjusted by the telescopic rod 62 as needed to ensure that the scraper plate 64 is in contact with the bottom surface of the sedimentation tank body 1, so that the sludge accumulated at the bottom and sides of the sedimentation tank body 1 that cannot be discharged can be scraped off, and the resulting sediment can be discharged from the sludge discharge pipe 7 and slide down to the sludge discharge pipe 7. The sludge discharge motor 7 is started to drive the spiral sludge discharge blades 72 to rotate, so that the sediment is discharged through the spiral sludge discharge blades 72. The water generated in the process of the sediment being transported and squeezed by the spiral sludge discharge blades 72 falls into the water collection tank 76 through the filter screen 75.

[0036] In this embodiment, the comprehensive treatment system for electroplating wastewater includes a recycled water treatment system and a discharge water treatment system. The electroplating wastewater is treated by the recycled water treatment system to obtain recycled water. The recycled water can be refluxed for continued use in the electroplating production process, and can also be circulated to the discharge water treatment system. The recycled water can meet the discharge standards after being treated by the discharge water treatment system.

[0037] The recycled water treatment system includes a mixed coagulation reaction sedimentation tank, which includes a sedimentation tank body 1. The recycled water treatment system also includes a mixed wastewater regulating tank, a sludge ceramsite adsorption and degradation reaction tank, a secondary sedimentation tank, an ozone oxidation reaction tank, a mixed intermediate water tank and a quartz sand filter. The upper part of one side of the sedimentation tank body 1 is connected to the mixed wastewater regulating tank through an inlet pipe, and the upper part of the other side of the sedimentation tank body 1 is connected to the sludge ceramsite adsorption and degradation reaction tank through an outlet pipe. The other side of the sludge ceramsite adsorption and degradation reaction tank is connected to the secondary sedimentation tank, the ozone oxidation reaction tank, the mixed intermediate water tank and the quartz sand filter in sequence. After the electroplating wastewater is separated and treated in the secondary sedimentation tank, the supernatant water enters the ozone oxidation reaction tank. The organic matter that is difficult to biodegrade in the electroplating wastewater is removed through the strong oxidizing effect of ozone.

[0038] When electroplating wastewater needs to be treated, it is first treated by the reuse water treatment system. The reuse water treatment system includes a mixed wastewater regulating tank, a mixed coagulation reaction sedimentation tank, a sludge ceramsite adsorption degradation reaction tank, a secondary sedimentation tank, an ozone oxidation reaction tank, a mixed intermediate water tank and a quartz sand filter. The mixed wastewater regulating tank prepares for subsequent treatment by adjusting the Ph value of the electroplating wastewater. The mixed coagulation reaction sedimentation tank generates precipitates by adding DTCR to react with heavy metals, and then forms large particle precipitates through the action of coagulants and flocculants to separate them from the wastewater, thereby separating the metal ions, and the supernatant flows to the sludge ceramsite adsorption degradation reaction tank. In the sludge ceramsite adsorption degradation reaction tank, ceramsite is used as a carrier to adsorb and degrade pollutants in the sewage through its surface biofilm and physical and chemical properties. Ceramsite is made of modified sludge and has adsorption capacity and a certain The hardness of sludge is taken as the main raw material and mixed with auxiliary materials such as clay and slag to form a filter material with a certain hardness and adsorption capacity. This filter material uses its porous structure and large specific surface area to provide a good attachment environment for microorganisms to form biofilms or biological communities. These microorganisms can degrade pollutants in sewage through metabolic activities. In addition, the particle size and pore structure of sludge ceramsite also give it a certain filtering ability, so that impurities such as suspended matter and colloids are trapped on the surface or pores of ceramsite, further purifying the water quality. It is then settled in the secondary sedimentation tank, and the supernatant water enters the ozone oxidation reaction tank. The strong oxidizing effect of ozone removes the organic matter that is difficult to biodegrade in the wastewater. Finally, it is lifted by a pump and enters the quartz sand filter for filtration to obtain recycled water that meets the standards of industrial recycled water. The recycled water can be refluxed and continued to be used in the electroplating production process.

[0039] The discharge water treatment system includes a discharge water regulating tank, a discharge coagulation reaction sedimentation tank, a discharge ozone oxidation reaction tank, a discharge intermediate water tank, an activated carbon filter and a water collection tank which are arranged in sequence.

[0040] When the recycled water needs to be further treated by the discharge water treatment system and then discharged in compliance with the standards, the recycled water is water that has been treated by the reuse water treatment system, so the recycled water mainly contains a small amount of heavy metals and organic matter. The recycled water first passes through the discharge water regulating tank for preliminary adjustment of Ph, etc., and then flows to the discharge coagulation reaction sedimentation tank. DTCR is added to the discharge coagulation reaction sedimentation tank to make the metal ions form chelate precipitates, and then coagulants and flocculants are added for coagulation reaction precipitation to remove the metal precipitates. The remaining organic matter in the supernatant is basically non-biodegradable. Therefore, the supernatant flows to the discharge ozone oxidation reaction tank. The discharge ozone oxidation reaction tank uses ozone oxidation to remove organic matter in the recycled water through the strong oxidizing effect of ozone, and then enters the discharge intermediate water tank, and is then pumped into the activated carbon filter. The effluent enters the collection tank for discharge in compliance with the standards.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
