The invention relates to the technical field of cyanide-free electroplating wastewater treatment, and discloses an auxiliary complexing heavy metal complex breaking assembly for cyanide-free electroplating wastewater treatment; the assembly comprises a complex breaking mechanism, the bottom of the complex breaking mechanism is movably connected with an extrusion strip, the top of the center of theextrusion strip is movably connected with an extrusion block, and the top of the extrusion block is fixedly connected with a connecting rod; and a strip wheel is arranged on the outer side of the connecting rod. According to the auxiliary complexing heavy metal complex breaking assembly for cyanide-free electroplating wastewater treatment, an activated carbon extrusion mechanism in a complex breaking pipe is stamped and extruded by scrap iron water, then an impact plate extrudes an impacted plate, and therefore an impact ball extrudes the outer surface of an activated carbon bin, and activated carbon water in the activated carbon bin flows out; the activated carbonized water is mixed with the scrap iron water to flow into the complex breaking bin, and the complex in the complex breaking bin is subjected to oxidation reduction under the action of the mixed water, so that precipitate is generated, and the complex in the wastewater is cleaned.
Description
technical field [0001] The invention relates to the technical field of cyanide-free electroplating wastewater treatment, in particular to an auxiliary complexing heavy metal decomplexation component for cyanide-free electroplating wastewater treatment. Background technique [0002] The electroplating industry is an important process for forming coatings, and it is also the main source of heavy metal pollution. In recent years, the traditional cyanide electroplating process has been gradually replaced by the cyanide-free process. In addition to the metal ions to be plated, the electroplating solution of the cyanide-free process also contains a Or a variety of high-concentration organic and inorganic complexing agents to optimize the quality of the plated parts, so as to improve the quality of the plated parts. [0003] The principle of electroplating is to apply a functional metal coating on the surface of the workpiece by electrolysis, so as to improve the service life and o...
