摘要
废线路板的利用处置可以创造可观的经济效益并有效缓解资源压力,但同时也存在较大的环境风险,尤其是重金属与有机物污染不容忽视。在简述了废线路板机械物理法、湿法冶金、火法冶金、热解法等典型利用处置技术的环境健康风险的基础上,重点分析了重金属、有机污染物、溴化污染物、浸出尾液等特征污染物的排放特性、防控技术及管理政策,并提出了规范提升废线路板利用处置行业污染防控水平的相关建议,有利于促进该领域绿色发展。
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.
