Embodiment 1

[0015] Embodiment 1, a treatment device for electroplating wastewater, such as figure 1 , including a waste water treatment tank 1, one end of the waste water treatment tank is connected to the water inlet pipe 2, and the other end is connected to the water outlet pipe 3; the high-voltage discharge electrode 4 is inserted into the cavity of the waste water treatment tank, and its end is located on the outside of the waste water treatment tank and connected with the high-power high-voltage pulse The positive pole of the power supply 5 is connected, and the negative pole of the high-power high-voltage pulse power supply is connected to the shell of the waste water treatment tank. By controlling its high-voltage pulse power supply, the high-voltage discharge electrode can generate strong glow discharge, and quickly generate high-concentration plasma, high-energy electrons, ozone and ultraviolet light in the interior space of the wastewater treatment tank. The material molecules i...

Abstract

The invention discloses a treatment device for electroplating wastewater. According to the invention, high-voltage discharge connected with a high-voltage pulse power supply performs glow discharge ina wastewater treatment box passing through electroplating wastewater to generate low-temperature plasmas, high-energy electrons, ultraviolet light and ozone, and through the advanced strong oxidationreaction of the low-temperature plasmas on the electroplating wastewater, comprehensive purification treatment integrating three effects of high-energy electron collision, ozone oxidation and ultraviolet light decomposition can be carried out on the wastewater; the method is simple in equipment, small in occupied area, low in investment, low in energy consumption and low in operation cost, and does not require any chemical reaction additives; the storage amount of the oxidized sludge is small, and secondary pollution is avoided; and the purified water can be recycled and discharged after reaching the standard.

Description

technical field [0001] The invention relates to a device and a method for treating electroplating wastewater. Background technique [0002] Electroplating is the use of chemical and electrochemical methods to plate various metals on the surface of metals or other materials. Electroplating technology is widely used in machine manufacturing, light industry, electronics and other industries. The composition of electroplating wastewater is very complex. In addition to cyanide (CN-) wastewater and acid-base wastewater, heavy metal wastewater is a potentially harmful category of wastewater in the electroplating industry. According to the classification of heavy metal elements contained in heavy metal wastewater, it can generally be divided into chromium (Cr)-containing wastewater, nickel (Ni)-containing wastewater, cadmium (Cd)-containing wastewater, copper (Cu)-containing wastewater, zinc (Zn)-containing wastewater, Gold (Au) wastewater, silver (Ag) wastewater, etc. The treatm...
