摘　　要：比较了几种碱性无氰镀铜螯合剂的环保特性与废水处理难度,分析了氧化破坏法、化学沉淀法和离子交换法处理螯合废水的优缺点,介绍了从碱、酸铜废水中回收铜粉以及HEDP镀铜液除铜和除HEDP的高效沉淀新技术。The environmental protection characteristics and wastewater treatment difficulty of various chelating agents used in non-cyanide alkaline copper plating were compared. The advantages and disadvantages of oxidative destruction, chemical precipitation and ion exchange method for chelating wastewater treatment were analyzed. New methods for recovering copper powder from acidic/alkaline copper-containing wastewater and the highly-efficient precipitation method for removing copper and HEDP from HEDP copper plating solution were introduced.
