1. Use the "acid precipitation-anaerobic-dosing activated sludge method" to treat circuit board organic wastewater, which has the three functions of removing COD, copper ions, and ammonia nitrogen. This method has good effects and is also the most economical technology;
2. Wastewater reuse process: pretreatment + RO system, the conductivity of the effluent reaches 100～150μs;
3. It adopts a three-level control system such as on-site control, central centralized control, and PLC industrial computer combined control, which is simple and convenient to operate and maintain, and the operation is stable and reliable.
