Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater treatment technology, and more particularly to a precipitation treatment device for nickel-containing electroplating wastewater. Background Technology

[0002] Nickel-containing wastewater in the electroplating industry refers to the cleaning water generated during nickel electroplating, as well as the wastewater discharged after pretreatment of highly concentrated nickel waste liquid and comprehensive wastewater from electroplating plants. Electroplating wastewater has a complex composition, containing a large amount of heavy metal ions and organic pollutants. Especially in electroless nickel plating wastewater, purification requires the addition of complex-breaking agents, followed by stirring and sedimentation, and treatment through chemical precipitation. However, current treatment devices mostly use single-stage sedimentation, resulting in incomplete purification. Furthermore, the precipitates are difficult to clean and discharge easily, and some unreacted substances and impurities coagulate and adhere to the inner wall of the sedimentation tank, making them difficult to clean and settle. The remaining impurities on the inner wall of the sedimentation tank affect the efficiency of subsequent reaction sedimentation. Utility Model Content
