The principle of electrocoagulation water treatment is that aluminum and iron are used as anodes. Under the action of direct current, the anode is dissolved and Al and Fe plasma is produced. After a series of hydrolysis, polymerization and oxidation of ferrous, the product reactions develop into various hydroxyl complexes, polynuclear hydroxyl complexes and even hydroxides, which make the colloidal impurities and suspensions in wastewater.

At the same time, the charged pollutant particles swim in the electric field, and part of the charge is neutralized by the electrode, which leads to the destabilization and precipitation.

Technical Data

Equipment characteristics

It mainly decomposes and separates the four main functions of electrochemistry: electrolytic oxidation, electrolytic reduction, Electro flocculation, and electrolysis flotation.

1. Electrolytic oxidation

Oxidation during electrolysis can be divided into two categories. One type is direct oxidation, that is, the pollutants lose oxidation directly at the anode and oxidize; the other is indirect oxidation, using an anion with a lower electrode potential in the solution, such as OH-, Cl-, which loses electrons at the anode to generate new ones. Strong oxidant actives such as [O], [OH], Cl2, etc. These active materials are used to oxidize and decompose BOD5, COD, NH3-N and the like in water.

2．Electrolytic reduction

The reduction in the electrolysis process can be divided into two categories. One type is direct reduction, that is, contaminants are directly reduced at the cathode to obtain electrons. The other type is indirect reduction, in which the cations in the contaminants first obtain electrons at the cathode, so that the electrons in the electrolyte at the cathode get electrons directly reduced to low-valent cations or metal precipitates.

3. Electrolytic flocculation

Soluble anodes such as iron, aluminum, etc., after high-voltage pulsed direct current, the anode loses electrons, forming metal cations Fe2+, Al3+, combined with OH- in solution to form highly active flocculating groups, which have strong adsorption capacity and excellent flocculation effect. In the ordinary flocculant, the adsorption and bridging of the waste water can be used to adsorb and remove the pollutants in the wastewater.

4. Electrolysis float

Electrolytic flotation is the electrolysis of wastewater. The ionization of water molecules produces H+ and OH-, and is directed to migrate under the electric field, and hydrogen and oxygen are separated on the surface of the cathode plate and the anode plate, respectively. The newly formed bubbles are very small in diameter, the hydrogen bubbles are about 10 to 30 μm, the oxygen bubbles are about 20 to 60 μm, the diameter of the bubbles (100 to 150 μm) generated when the pressurized dissolved air is floated, and the bubbles generated during mechanical stirring. The diameter (800 ~ 1000μm) should be small. From this, it can be seen that the bubble generated by the electrolysis has higher ability to trap the impurity particles than the latter two, and the dispersion of the bubble is high, and the carrier adheres to the suspended solid in the water, so that the contaminant can be easily removed. Electrolytic air flotation can remove both hydrophobic pollutants in wastewater and hydrophilic pollutants in wastewater.
