Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid recovery, in particular to an environmentally friendly device for concentrating and recovering nickel electroplating waste liquid. Background Art

[0002] Electroplating nickel waste liquid is a common wastewater in the electroplating industry, mainly from the cleaning water in the electroplating nickel process, the stripping liquid of the plating tank corner, the chemical nickel plating liquid, the waste plating tank liquid, etc. Electroplating nickel waste liquid mainly contains high concentrations of nickel ions, and the concentration is usually high. Nickel is a heavy metal with strong toxicity, which has certain harm to the ecological environment and human health. In addition to nickel ions, electroplating nickel waste liquid may also contain other metal ions, such as copper, cobalt, iron, chromium, etc., as well as impurities such as nitric acid, sulfuric acid, and chloride. The pH value in the waste liquid is usually low and the acidity is strong, which makes the treatment of wastewater more difficult. As the use time of the nickel plating tank liquid increases, ions such as iron, copper, zinc, and nickel will accumulate, and some organic additives will also become ineffective, all of which will cause the generation of waste liquid.

[0003] Traditional methods for treating electroplating nickel wastewater include precipitation, filtration, ion exchange, etc., but these methods are no longer suitable for modern efficient, energy-saving and environmentally friendly industrial production. Electrolysis is a newer treatment method that can effectively remove nickel ions and some organic matter from wastewater by adjusting parameters such as pH, current density and conductivity. The ion exchange method enriches the metal ions in the wastewater in the exchange agent through ion exchange between the solid phase and the liquid phase, thereby realizing the secondary recycling of valuable heavy metals. The wastewater needs to be filtered before electrolysis to prevent excessive impurities from affecting the efficiency of wastewater recovery. Utility Model Content
