14 Industrial Wastewater Treatment Principals and Ideas
14 Industrial Wastewater Treatment Principals and Ideas

The main treatment measures for cyanide-containing wastewater are: (1) Reforming the process to reduce or eliminate the effluent containing cyanide. If the cyanide-free plating method is used, the industrial wastewater in the electroplating workshop can be eliminated. (2) Waste water with high cyanide content should be recycled.
