There are so many types of commonly used batteries, do they all have to be recycled? Simply put, as long as the dry battery weighs less than one kilogram, it can be recycled. Take the disposable primary battery as an example, whether it is a barrel type battery suitable for clocks, flashlights, toys, that is, the 1st, 2nd, 3rd, and 4th batteries we know well, as well as watches, ear thermometers, hearing aids The button cells in ... are all dry cells that should be recycled. A03(1) Photo Credit: Wikipedia There are many types of batteries, and the recycling methods of each battery are different, but they should be properly recycled so as not to cause harm to the environment.
And rechargeable secondary batteries, such as nickel-cadmium batteries in electric appliances, nickel-metal hydride batteries in telephones, laptops, and Special Database even lithium batteries in digital cameras, can also be rded 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 screening and magnetic separation procedures.
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.
