摘要
随着科技的进步和电子信息产业的迅速发展,人们的消费观念的改变,电子产品更新换代的速率日益加快,导致了大量电子废弃物的产生。印刷线路板和塑料作为电子产品不可或缺的部分,具有成分复杂,含有多种资源和环境污染物质等特点。因此,废弃印刷线路板和塑料的回收处理越来越受到人们的重视。回收处置电子废弃物所采用的主要是热处理、湿法处理、机械处理以及生物处理等方法,在处理的过程中通常会产生二次污染。文章主要对印刷线路板和家电塑料两种电子废弃物的处理方法,处理过程中产生的污染进行了综述,并对处理过程的污染控制进行了探讨。
A large amount of electronic waste produced because of the rapid development of electronic information industry and the progress of science and technology, at the same time, people's consumption concept changed and the electronic products renewal speed increasingly accelerated, lead to our country electronic waste pollution problem more serious. Printed circuit boards and plastic as electronic products indispensable part, they contains a variety of metal resources and environmental pollutions. Therefore, people pay more attention to E-waste recycling. At present, the methods of reclamation of E-waste primarily are mechanical treatment, heat treatment, chemical processing and biological treatment. Secondary pollution usually produces in the process of disposing. Methods for the processing of printed circuit boards and plastics in electric household appliances and the pollutions produced during the process of disposing are summarized, the pollution control of the process of recycling are discussed.
