The comprehensive electroplating wastewater from a large-scale electroplating industrial area in Shenzhen has been studied. Its treatment method has been investigated. It is ascertained that acidification-oxidation decomplexation and chemical precipitation of hydroxide and sulphide process are used. The best decomplexation agent chosen is bleaching liquid NaClO. The operational parameters are as follows: dosage of bleaching liquid 1.2 mL/L wastewater, reaction pH 2.3, and reaction time 2 h. Under these conditions, the requirements of the discharge standard of electroplating wastewater can be met effectively by adjusting the pH and adding sodium sulphide, overcoming the deficiencies of traditional processes of electroplating wastewater treatment.
