The wastewater generated during the production process of circuit boards contains copper ions, complex heavy metals, organic compounds, and acid-base pollutants, mainly from processes such as grinding, etching, and electroplating. The processing technology includes steps such as classified collection, network breaking, chemical precipitation, biodegradation, and membrane separation, with the goal of achieving water resource reuse and zero pollution emissions, which is a key link in the green transformation of the electronic manufacturing industry.
