Electroplating sludge is the “end state” of wastewater treatment in the electroplating industry, which contains a large amount of precious metals such as copper, nickel, chromium, iron and zinc.

The electroplating sludge is mainly derived from the solid waste generated by various electroplating waste liquids and electrolytic bath liquids in industrial electroplating plants. The chemical components of electroplating sludge are quite different due to the different production processes and treatment processes of electroplating manufacturers. Complex, mainly containing heavy metal compounds such as chromium, iron, nickel, copper, zinc and soluble salts.

The electroplating sludge treatment equipment developed by Suli Drying dries the electroplated sludge material with a water content of 75% or more to a water content of 40% to 65%; the dried material is uniformly mixed with coal, and the mixture is added to the sintering furnace. Sintering.
