Printed circuit board wastewater treatment technology

 

Technical features:

1. Using biological treatment technology, using the decomposition enzyme of microbial anaerobic bacteria, completely remove the chelating agent and complexing agent in the complex wastewater, so that it permanently loses the chelation and complexing ability;

2. The organic acid wastewater from the circuit board is treated by the “acidification-anaerobic-administered activated sludge method”, which has the functions of removing COD, copper ions and ammonia nitrogen. The method has good effect and is the most economical technology;

3, wastewater reuse process: pretreatment + RO system, the effluent conductivity reaches 100 ~ 150μs;

4. It adopts three-level control system such as on-site control, central centralized control and PLC industrial computer joint control. The operation and maintenance are simple and convenient, and the operation is stable and reliable.

5. Using the company's unique technology, the etching solution and the micro-etching waste liquid are directly made into sponge copper, and the supernatant liquid can also be used as a broken complexing agent.

 

 

Electroplating wastewater treatment technology

 

Technical features:

1. The wastewater of the workshop is classified and collected according to the type of plating and the type of complexing such as electroplating additives, and then separately pre-processed according to the classification type to reduce the running cost;

2, online monitoring and automatic switching from the engineering technology to achieve the diversion of wastewater;

3. The system realizes full-automatic operation, online monitoring of operating parameters, ensuring the accuracy and stability of the system operation, reducing manual operation errors and waste of medicaments.

4. According to the type of complexation, it is determined that the complexation is carried out online under acidic/alkaline conditions.
