In recent years, with the rapid development of the electronics industry, PCB manufacturing volume has also increased year by year. However, PCB manufacturing companies will produce a large amount of copper-containing wastewater during processes such as etching, pickling, brushing and washing. Copper is a valuable resource. It has a certain recycling value. If it is not processed properly, it will not only have a serious impact on the environment, but also cause serious waste of resources.
