During the manufacturing process of PCB boards, the substrate needs to be copper-immersed, copper-coated and copper-ground, and in the process of copper-ground boards, the conventional equipment will discharge the wastewater generated from the grinding of boards (which contains a large amount of copper powder) directly into the sewage tank, and will consume a large amount of water for rinsing. If not treated, this copper-containing wastewater will not only pollute the environment, but also cause a waste of resources. Therefore, in the PCB (printed circuit board) manufacturing industry, copper powder recovery water treatment system is particularly important.
