Abstract

The invention provides a method for recycling phosphorous electroless nickel plating solution element in a wet process of surface treatment. The method comprises the following steps of: performing chlorine removal treatment on the plating solution or washing solution to remove chlorine by utilizing a carbon-fiber filter; carrying out separating by using a separation device; carrying out adsorption treatment by using an adsorption device with resin to adsorb residual impurities and produce recycled washing solution at a deionized water level; carrying out sedimentation and separation by using a sedimentation and separation device so as to remove a heavy metal catalyst and produce precipitated and separated recycled solution; purifying by using a purification device to produce calcium-contained solution and acid-contained recycled solution; and mixing by using a mixing device, mixing the recycled washing solution, the precipitated and separated recycled solution and the acid-contained recycled solution to obtain recyclable regenerated solution. Therefore, according to the method provided by the invention, the recycling of the nickel resource can be improved and waste reduction and zero discharge can be achieved.

Description

technical field [0001] The present invention particularly relates to a method for recycling the plating solution components of electroless nickel plating, which recovers the hypophosphite type electroless nickel (Hypophosphite Type Electroless Nickel) by using a nano screen device and a reverse osmosis membrane device in the surface treatment wet process Nickel contained in plating or cleaning solutions. Background technique [0002] Many mechanical equipment, production tools, semiconductor products, or electronic component carriers require specific surface treatments to improve their surface mechanical strength and prevent scratches or cracks, or to improve oxidation or corrosion resistance, or to strengthen bonding, or to enhance Visual aesthetics. Since nickel has very good protective functions, such as acid resistance, alkali resistance, and corrosion resistance, electrolytic nickel plating or electroless nickel plating is generally used for surface treatment to form a...
