1, solidified and buried deeply
Where the state stipulates that waste batteries can be buried, first wrap the batteries in plastic bags or cartons, and then dig a big pit and bury the waste batteries in the pit.
2. Classified delivery
There are a lot of waste batteries at home, which should be handed over to our street office for disposal.
Step 3 recycle
Put the waste battery in the trash can for recycling, and then use it reasonably after the sanitation workers recycle it. Different batteries should be handled separately, and dry batteries and rechargeable batteries should be separated.
Lead storage battery is the most widely used industrial battery in China, and lead accounts for more than 50% of the total battery cost. Pyrolysis, hydrometallurgy and solid-phase electrolytic reduction technology are mainly used. The shell is made of plastic, which is renewable and basically realizes no secondary pollution.
Harm of waste batteries
When the chemical reaction inside the battery is completed, the battery can no longer supply power and become a waste battery. Usually, people just throw it away and buy another one. Most people would say this is normal. But they didn't think that in that gesture, they were also destroying their home-the earth. The battery doesn't look so destructive, but you can't see everything on the surface. Waste batteries contain a lot of heavy metals, such as mercury, cadmium, manganese and lead.
When the surface cortex of waste batteries rusts in the sun and rain, its components will penetrate into soil and groundwater. Once people eat crops produced on polluted land or drink polluted water, these toxic heavy metals will enter people's bodies and slowly deposit, posing a great threat to human beings.
