A small dry battery in the stomach of the electrical appliance is as light as a feather in the hand, and it does not look amazing, but it contains a great amount of energy to supply our daily electricity needs. On the other hand, the acid or alkaliries, such as nickel-cadmium batteries in electric appliances, nickel-metal hydride batteries in telephones, laptops, and even lithium batteries in digital cameras, can also be recycled. As for lead-acid batteries, and batteries that must be supplemented with electrolyte or other substances to supply power, they are not included, and you must contact a legal resource recovery company, an automobile and motorcycle repair factory, and an electromechanical industry for assistance in recycling. Different types of dry batteries may contain various heavy metals, which will pollute soil and groundwater sources, and even enter our body to endange Special Database our health, but if they are properly recycled, the benefits outweigh the disadvantages! Iron, manganese, zinc, cobalt, lithium, nickel, cadmium, and plastic in batteries are all useful substances that can be reused as raw materials after being separated by a processing plant. Taking the familiar cylindrical manganese zinc and alkaline manganese batteries as an example, the current recycling process can be divided into the main steps of sorting, crushing, screening, and negative pressure mercury removal. The treatment plant first separates manganese-zinc and alkaline-manganese batteries from the recyclables, and then shreds the shells, and then separates manganese dioxide, scrap iron, scrap zinc and other recycled materials through procedures such as screening and magnetic separation. Next, a special machine is used to remove the mercury in the battery by a negative pressure high temperature method, and the other in the regenerated material is removed by a condenser, a bag filter, a wet scrubber and an activated carbon adsorption tank. Contaminants are filtered out. The remaining pollutants such as wastewater, sludge, acid-base liquid, etc. will be finally disposed of by incineration, solidification and landfill to avoid harming the environment.
