Highlights

The serious environmental pollution is caused by gold hydrometallurgy wastewater due to containing large amount of inorganic salts,various heavy metals,ammonia nitrogen,cyanide and COD,etc.,but the target discharge of wastewater cannot be achieved by the present treatment technologies.A series of key technologies for advanced treatment and desalination reuse of gold hydrometallurgical wastewater have been developed,including waste acid purification and resource,valuable metal recovery and heavy metal removal,cyanide recovery by hydrophobic membrane,organic matter removal by advanced oxidation,electrodialysis desalination,etc.The key technologies were integrated for collaborative control and resource utilization of multiple pollutants,to establish the engineering package of multi pollutant collaborative control and resource for gold hydrometallurgy wastewater and to form a complete technology and equipment.The application feasibility of related technologies was verified by field test.The industrial application of the technology has been promoted for achieving the goal of advanced treatment and near zero discharge of gold hydrometallurgical wastewater.
