The invention discloses a wastewater recovery technology on a rack plating production line. The technology comprises the following steps: 1, pretreating: sequentially filtering rack plating wastewater containing heavy metal ions by using a mechanical filter, an activated carbon filter and a filter to obtain primary water; 2, nano-filtering: allowing the primary water to pass through a nanofiltration system to intercept the heavy metal ions and other impurities and make 90% or more of the primary water become highly-pure secondary water after permeating a nanofiltration membrane element; and 3, carrying out reverse osmosis separation: allowing the secondary water to pass through a reverse osmosis filter membrane in order to obtain pure water for production. The recovery technology can be used to recover 90% or more of the wastewater in order to obtain the pure water for production, and the pure water for production can be directly used as water for rack plating.
Description
technical field [0001] The invention relates to a waste water recovery technology, in particular to a waste water recovery technology on a rack plating production line. Background technique [0002] The gantry type linear electroplating production line is suitable for copper plating, nickel, chromium, zinc, aluminum oxidation, phosphating, plastic electroplating and other advanced process requirements, and can meet various functional and decorative requirements in electroplating according to user needs. The whole line has reasonable structure, beautiful appearance and convenient operation, and can design two kinds of full-automatic and semi-automatic operations according to customer requirements. The computer-programmable fully automatic operating system can be displayed on the screen and has high stability. The rollers of the gantry driving are made of polyurethane rubber, running smoothly and without noise. The whole line realizes process control, frequency conversion spee...
