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.

以深圳某大型电镀工业园产生的综合电镀废水为研究对象，对其处理方法进行了探索，确定了酸化-氧化破络反应及氢氧化物和硫化物共沉淀的处理方法；通过实验选择漂水为最佳破络剂，最佳破络操作参数为漂水用量1.2 mL/L，反应pH为2.3，反应时间2.0 h，在此基础上调节pH并加入硫化钠即可实现电镀废水的达标排放，克服了传统电镀废水处理工艺的不足。
