Electroplating wastewater treatment device

Electroplating wastewater treatment device

Detailed description

The electroplating wastewater treatment machine uses the electrochemical reaction in the electrolytic cell and combines electrolytic redox, electrolytic air flotation, and electrolytic flocculation. It has the advantages of low investment, easy installation and maintenance, small footprint, stable performance, and good governance. Governance ideal equipment. For chromium, copper, zinc, nickel and other heavy metal ion wastewater, it can ensure that the discharge is up to standard. At the same time, it is also widely used in the treatment of leather, printing and dyeing, slaughtering, cyanide, hospital, emulsion and other wastewater treatment.

I. Structural composition and working principle:

Structure: It consists of electrolytic tank, inclined plate sedimentation tank, filter tank and electric control box.

Principle: Soluble iron is used as the anode. Under the action of direct current, the anode generates ferrous ions. Under acidic conditions, hexavalent chromium is reduced to trivalent chromium. When a certain voltage is reached between the plates, the cathode emits oxygen and the anode is near the anode. Ferric hydroxide is formed, and hexavalent chromium is continuously reduced in a weak acid and neutral medium to form a hydroxide precipitate, which is then discharged after filtration to achieve the purpose of treatment.
