化学镀铜废液的处理

介绍了处理化学镀铜废液经济有效的方法。采用氧化还原法和沉淀法回收金属铜和EDTA,并利用漂白粉除去酒石酸钾钠。之后的废液由活性碳-Fenton-超声联合降解其中的有机物,降低其COD值至国家排放标准,从而达到保护环境和节约成本的目的。

Treatment of Cu-plating Wastewater

Wastewater from the chemical copper-plating process was treated by an economic and effective method. In order to decrease the cost, save the resource and protect the environment, copper and EDTA were recycled by oxidation-reduction and precipitation method, respectively;And seignette salt was removed by bleach. Then, the combined process of activated carbon, Fenton and ultrasonic was used to degrade other organic materials to make the chemical oxygen demand （COD） value reach the national discharge standard.
