含铜废水处理技术现状

The Current State of the Technology Treating Wastewater Containing Copper

含铜废水主要来源于工业生产过程,如不经过适当处理排入环境,将给环境带来极大危害。含铜废水的主要处理方法有化学沉淀法、离子交换法、电解法等。由于各生产过程不同,废水中铜的存在状态与价态都各有差异,对于不同类型含铜废水的处理应依据废水性质,选用不同工艺或工艺组合对废水进行处理,以满足排放标准的要求。同时在处理含铜废水时,应考虑处理后出水的回用和废水中铜的资源化问题。

The wastewater containing copper came from the process of industry producing, if not properly treated and discharged into environment, it would bring huge harm to human. The treatment methods of the wastewater containing copper included chemical sedimentation, ion exchange, electroanalysis, etc.. Because of the differences between the producing process and the copper form and ions value, the treating method or technology should be chosen according to wastewater＇s characteristics in order to meet the discharge standard, and effluent recycle and copper recovery should be taken into account.
