Abstract:In view of the unclear physical and chemical properties of electroplating sludge in Qingdao area, this paper takes electroplating sludge produced in four typical industrial parks in Qingdao as the research object, systematically compares the basic properties of water content, organic matter content, pH, element composition, crystal composition, total heavy metal content, toxicity of heavy metal leaching, particle size distribution of electroplating sludge, and the results show that four kinds of electroplating sludge have different properties. The heavy metal content in the electroplating sludge is relatively high, which has the precondition of resource utilization, and provides data support for future resource utilization of electroplating sludge.
