The treatment of electronic waste mainly includes the following steps:
1. Disassembly: Dismantle and disassemble discarded electrical and electronic products manually or mechanically for subsequent recycling and disposal.
Classification: Classify the disassembled electronic waste, such as separating different types of circuit boards, screens, batteries, etc., for targeted treatment.
2. Treatment and recycling:
Recycling: Extract valuable substances from electronic waste, such as metals, plastics, etc., for processing, manufacturing and assembly to produce new electronic products and parts.
3. Physical treatment: Separate, transform or solidify harmful substances through heating, chemical dissolution, etc.
4. Chemical treatment: Also known as wet treatment, electronic waste particles are put into acidic or alkaline liquids, and high-grade metals are finally obtained after a series of chemical reactions.
5. Incineration treatment: The electronic waste that cannot be recycled is incinerated at high temperature, but harmful gases and waste will be released in this process, which requires environmental protection treatment.
6. Reuse: Reuse electronic devices that can still be used or repaired, such as donating, reselling or leasing. In addition, the following points should be noted for the treatment of electronic waste:
The treatment process must comply with relevant laws and regulations, especially those on environmental protection and resource utilization.
Electronic devices may store private information and commercial secrets, and the security of this information must be ensured before treatment. To increase the recycling rate of electronic waste, we can set up special electronic waste recycling points and promote the recycling of electronic products.
In summary, the treatment of electronic waste is a complex and professional process that aims to reduce pollution to the environment and achieve effective use of resources.
