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.
