摘　　要：介绍了线路板厂含铜蚀刻废液提取氧化铜后的废水处理方法及应用实例,结果表明:采用文中介绍的方法分别处理以上废水,能实现对废水中的铜及氨氮的回收处理,处理后的废水中铜、氨氮、COD等含量均能达到国家规定的排放标准。文中介绍的废水处理组合工艺具有加药量少、污泥产生量少、处理成本低等优点。The methods and application cases of wastewater were introduced in the paper. The PCB etching liquid contains a lot of copper, and the copper were collected as copper oxide. Meanwhile a lot of wastewater generates in this process, so we developed a kind of method to treat the water respectively. The treated water can achieve wastewater emission standard.
