Abstract: As national requirements of industrial energy conservation and emission reduction becomes more and more strict, the printed circuit board (PCB) industry has to solve the environmental treatment problems before better development. The main pollution sources and treatment status of PCB industry, i.e. the treatment status of PCB wastewater, waste etchant and sludge containing copper, were analyzed. The environmental technology requirements of this industry were put forward, including the wastewater treatment technologies for wastewater containing complex state copper, small and mid-sized enterprise wastewater, and PCB wastewater deep treatment and reuse, the waste etchant technologies in regenerating and recycling, and the recycling, stabilization and harmlessness technologies for the sludge containing copper. Suggestions on better solving the environmental problems and health development of this industry were put forward.
