Description

Technical Field

[0001] This utility model belongs to the technical field of heavy metal ion removal equipment, specifically referring to a heavy metal ion adsorption and removal device for wastewater. Background Technology

[0002] Heavy metals, primarily referring to mercury, chromium, cadmium, lead, arsenic, copper, zinc, cobalt, and nickel, are a significant class of pollutants in environmental pollution control. During production processes in industries such as mining, metallurgy, electroplating, and chemicals, heavy metal pollutants enter natural water bodies along with industrial wastewater. In these water bodies, they accumulate through the food chain of plants and animals, ultimately posing a threat to human health. Therefore, it is necessary to adsorb and remove heavy metal ions from wastewater.

[0003] However, existing heavy metal ion adsorption and removal devices rely on a single adsorption structure, making it difficult to completely adsorb and remove metal ions from wastewater, thus affecting the quality of wastewater treatment. Utility Model Content

A water inlet pipe is threaded to the top of the activated carbon adsorption tube, and a drain pipe is threaded to the bottom of the porous ceramic adsorption tube.

[0006] Preferably, the chemical adsorption structure includes a base, a chemical adsorption tank, a second drain pipe, a filter screen, a second fixing seat, a motor, a stirring shaft, and stirring teeth.

The fixed base 4 is fixedly mounted on the upper part of the support frame 1. The activated carbon adsorption tube 5, the activated carbon adsorption tube 6, the iron oxide adsorption tube 7, the porous ceramic adsorption tube 8, and the porous ceramic adsorption tube 9 pass through the fixed base 4 and are fixedly installed. 26. Iron oxide adsorption tube 7, porous ceramic adsorption tube 1 8, and porous ceramic adsorption tube 2 9 are arranged in parallel. One end of connecting bend 10 is threaded to the bottom of activated carbon adsorption tube 1 5, and the other end is threaded to the bottom of activated carbon adsorption tube 2 6. One end of connecting bend 2 11 is threaded to the bottom of porous ceramic adsorption tube 1 8, and the other end is threaded to the bottom of porous ceramic adsorption tube 2 9. One end of connecting bend 3 12 is threaded to the top of activated carbon adsorption tube 2 6, and the other end is threaded to the top of iron oxide adsorption tube 7. One end of connecting bend 4 13 is threaded to the top of porous ceramic adsorption tube 1 8, and the other end is threaded to the top of porous ceramic adsorption tube 2 9.

Water inlet pipe 14 is threaded to the top of activated carbon adsorption tube 1 5, and drain pipe 15 is threaded to the bottom of porous ceramic adsorption tube 2 9.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the chemical adsorption structure 3 includes a base 16, a chemical adsorption tank 17, a second drain pipe 18, a filter screen 19, a second fixing seat 20, a motor 21, a stirring shaft 22, and stirring teeth 23. The base 16 is fixedly mounted on the support frame 1, the chemical adsorption tank 17 is fixedly mounted on the base 16, the first drain pipe 15 is connected between the top of the chemical adsorption tank 17 and the second porous ceramic adsorption tube 9, the second drain pipe 18 passes through the support frame 1 and is fixedly connected to the base 16 at the bottom of the chemical adsorption tank 17, the filter screen 19 is fixedly mounted on the top of the second drain pipe 18, the second fixing seat 20 is fixedly mounted on the upper side of the support frame 1, the motor 21 is fixedly mounted on the second fixing seat 20, the stirring shaft 22 is fixedly mounted on the output shaft of the motor 21, and the stirring teeth 23 are fixedly mounted on the stirring shaft 22.

[0020] In practical use, activated carbon is added to activated carbon adsorption tube 5 and activated carbon adsorption tube 6, iron oxide is added to iron oxide adsorption tube 7, porous ceramic is added to porous ceramic adsorption tube 8 and porous ceramic adsorption tube 9, and finally ion exchange resin is added to chemical adsorption tank 17. The inlet pipe 14 is then connected to the waste discharge pipe. At this point, wastewater containing a high concentration of pollutants is discharged through inlet pipe 14 into activated carbon adsorption tube 5, where it undergoes adsorption by the activated carbon. The wastewater then flows through bottom-connected bend pipe 10 into activated carbon adsorption tube 6, where it undergoes further adsorption by the activated carbon. Finally, it flows through top-connected bend pipe 12 into iron oxide adsorption tube 7, where it undergoes further adsorption by the iron oxide. The wastewater is first adsorbed, then discharged from the bottom through the bend pipe 11 into the porous ceramic adsorption tube 8, where it is adsorbed again by the porous ceramic. Finally, it is discharged through the bend pipe 13 into the porous ceramic adsorption tube 9, where it is adsorbed again by the porous ceramic, thereby reducing the concentration of heavy metal ions in the wastewater. The wastewater with low concentration of heavy metal ions is then discharged into the chemical adsorption tank 17. Then, the motor 21 drives the stirring teeth 23 on the stirring shaft 22 to stir the wastewater and ion exchange resin to fully mix and adsorb. Finally, the valve at the bottom of the drain pipe 18 is opened to discharge the treated water from the chemical adsorption tank 17, thus achieving complete removal of heavy metal ions. The above is the entire process of using the heavy metal ion adsorption and removal device in wastewater.
