[0002] Electroplating sludge is a hazardous waste generated during the wastewater treatment process of the electroplating industry. It is mainly composed of heavy metal hydroxides and may contain harmful substances such as copper and chromium. The treatment and disposal of electroplating sludge is an important branch of environmental engineering, mainly because the heavy metals and other harmful components it contains pose a threat to the environment and human health. In the process of treating electroplating sludge, it is necessary to slurry the electroplating sludge by stirring. Electroplating sludge slurrying refers to a process of subjecting the heavy metal-containing sludge generated during the electroplating process to a series of treatments to reduce its harm to the environment and realize resource utilization. However, most of the electroplating sludge slurrying stirring devices currently used are not equipped with heating devices.
