Problems solved by technology
However, even for enterprises that have obtained the qualification for the treatment of waste electrical and electronic products, their treatment processes still use the traditional "burning" (burning the plastic to leave the metal, producing a large amount of waste gas and residue) and "washing" (using strong acid or "aqua regia") "Dissolve metals, acid-soaked plastics are discarded and become new garbage), the resource utilization rate is low, and a large amount of waste water, waste gas, and waste residues are generated during the treatment process, causing serious pollution to air, rivers, groundwater, and land.

Description
technical field [0001] The invention relates to the technical field of waste treatment, in particular to a treatment device for electronic waste. Background technique [0002] China scraps more than 5 million TV sets, 4 million refrigerators, 5 million computers and 60 million mobile phones every year, generates more than 2.3 million tons of electronic waste every year, and is increasing year by year, and imports more than 14 million tons of electronic waste through illegal channels . Therefore, my country needs to deal with more than 16.3 million tons of electronic waste every year. my country's "Regulations on the Management of Waste Electrical and Electronic Products Recycling and Disposal" implemented on January 1, 2011 stipulates that waste electrical and electronic product recycling operators who process recycled waste electronic products shall obtain the qualification for processing waste electrical and electronic products. However, even for enterprises that have ob...
