Background:
Electroplating is an important process in the electronics industry, but the wastewater generated during the electroplating process contains heavy metal ions (such as copper, nickel, chromium, etc.) and organic matter, making it difficult to treat.
Solution:
The electronic industry enterprise adopts a comprehensive treatment process combining chemical precipitation, ion exchange, electrodialysis, and reverse osmosis. Firstly, the majority of heavy metal ions in wastewater are removed through chemical precipitation; Then, use ion exchange resin to further remove residual heavy metal ions; Next, remove salt from the wastewater through electrodialysis technology; Finally, reverse osmosis membrane technology is used to ensure that the effluent quality meets the reuse standards. The entire processing process has achieved automated control and intelligent management, ensuring zero discharge of wastewater.
