Problems solved by technology
The key technology of the adsorption method is the choice of adsorbent. The traditional adsorbent is activated carbon. Activated carbon has strong adsorption capacity and high removal rate, but the regeneration efficiency of activated carbon is low, and the quality of treated water is difficult to meet the reuse requirements. The price is expensive and the application is limited.
When heavy metals settle, they need to be filtered, and when the sediment is recovered, the water flow needs to be closed, and then the filtered matter is screened out, which is cumbersome and inefficient.

The invention discloses an environment-friendly reaction device for oxidatively adsorbing and recycling heavy metal ions in industrial wastewater. The environment-friendly reaction device comprises a box body, wherein the right upper end of the box body is fixedly connected with a support plate; the support plate is sleeved with a magnesium rod; the magnesium rod is fixedly sleeved with a limiting ring; the upper end of the magnesium rod is fixedly sleeved with a clamping sleeve; a wire connector is fixedly inserted into the middle of the clamping sleeve and connected with the magnesium rod; the left upper end of the box body is fixedly sleeved with a graphite rod; the left lower end of the box body is fixedly connected with a filter device; and the upper end of the filter device is sleeved with a hose through a hoop. The environment-friendly reaction device for oxidatively adsorbing and recycling the heavy metal ions in the industrial wastewater is used for adsorbing heavy metal ions in the wastewater through magnesium hydroxide generated by an electrolytic method; sediments generated by the heavy metal ions can be filtered by using the filter device; and a liftable water passing pipe is capable of filtering out the filtered sediment and recycling the sediments while sealing water circulation, so that the environment-friendly reaction device is convenient and fast.
Description
technical field [0001] The invention relates to the technical field of heavy metal environmental protection filtering equipment, in particular to an environmental protection reaction device for oxidation, adsorption, recycling and recovery of heavy metal ions in industrial wastewater. Background technique [0002] Industrial wastewater refers to the wastewater and waste liquid discharged during the process of production, which contains industrial production materials, intermediate products, by-products and pollutants generated during the production process, which is an important cause of environmental pollution, especially water pollution. , Industrial wastewater contains heavy metal ions, which seriously endanger the natural environment. The adsorption method is often used to adsorb heavy metal ions to achieve the purpose. Adsorption method is an effective method to use porous solid substances to adsorb and remove heavy metal ions in water. The key technology of the adsorpt...
