| Abstract: |
| Utilization and disposal of waste printed circuit boards (WPCBs) can create considerable economic benefits and effectively alleviate pressure of resources, but there are also greater environmental health risks, especially heavy metal and organic pollution. Environmental health risks of typical utilization and disposal technologies of WPCBs, such as physical method, hydrometallurgy, pyrometallurgy, and pyrolysis, were briefly described. On this basis, emission characteristics, prevention and control technologies and management policies of characteristic pollutants such as heavy metals, organic pollutants, brominated pollutants and leaching tail liquor were analyzed. Relevant suggestions were put forward to standardize and improve pollution prevention and control level of waste printed circuit board utilization and disposal industry, which is conducive to promoting the green development in this field. |
