The electroplating wastewater treatment device uses electrolysis The electrochemical reaction in the tank integrates electrolytic redox, electrolytic flotation, electrolytic decolorization and deodorization, and electrolytic flocculation. It has the advantages of low investment, easy installation and maintenance, small footprint, stable performance, and good treatment effect. For chromium, It can mix wastewater with heavy metal ions such as copper, zinc, and nickel to ensure discharge standards. It is also widely used in leather, printing and dyeing, slaughtering, cyanide-containing, fluorine-containing, arsenic-containing, hospital, emulsion and other wastewater treatment. (For gold, silver and nickel wastewater can be recycled).
1. Structural composition and working principle
Structure: composed of electrolytic tank, inclined plate sedimentation tank, filter, electric control box, etc.
Principle: (taking hexavalent chromium as an example) using soluble Iron serves as an anode. Under the action of direct current, ferrous ions are precipitated from the anode. Under acidic conditions, hexavalent chromium is reduced to trivalent chromium. When a certain voltage is reached between the plates, oxygen is precipitated from the anode and iron hydroxide is formed near the cathode. , continue to reduce hexavalent chromium in weak acid and neutral media, generate hydroxide compounds and precipitate, and then discharge after filtration to achieve the purpose of treatment. Ensure stable compliance. For cyanide, it is equipped with a cyanide breaking device.
Features:
It can treat a variety of mixed ion wastewater at the same time.
, ensuring stable compliance with standards (lower than national emission standards), small footprint, and easy operation and maintenance.
The installation of the process equipment and the construction of the pool can be adapted to local conditions, either by reusing old ones or building new ones, above ground or underground, or placed in straight lines or folded lines, and are highly adaptable.
This process meets the requirements of civilized and clean production. Scum, sludge and purified water go their own way. There is no leakage or leakage at the treatment site, achieving civilized management and civilized operation.
On the basis of introducing and assimilating foreign advanced technology, our company has independently researched and developed an internationally advanced horizontal sedimentation spiral automatic discharge energy-saving centrifuge, which has wide application, clean working ring, and better dehydration performance. It has the advantages of larger processing capacity, better separation effect, energy saving and drug saving, low comprehensive operation cost, small floor space, low labor intensity, and high degree of automation. The mechanical properties of the product are much higher than the standards of the "Machine Industry Standard B of the People's Republic of China (Spiral Discharge Decanter Centrifuge)".
