1. Introduction to Electric Fenton and Traditional Fenton:
1. Electric Fenton is a Fenton-like reaction that uses 0 valence iron plates to form ferric iron under the action of electric current, and then reacts with hydrogen peroxide to produce hydroxyl radicals, which is called electric Fenton reaction.
2. The traditional Fenton is reacted by adding ferrous sulfate and hydrogen peroxide externally, which forms a strong oxidation reagent to oxidize the organic matter in the water.
2. The difference between electric Fenton and traditional Fenton:
1.The electro-Fenton equipment can continuously produce highly active Fe2+ and H2O2 through electrolysis, which overcomes the phenomenon of uneven degradation rate of organic matter in the chemical Fenton method, and ensures a balanced reaction and continuous high efficiency
2.Compared with the traditional Fenton method, the electric Fenton equipment does not need to add a large number of chemicals on site, and has the characteristics of less dosing, cost saving, and less sludge generation
3.In addition to the oxidation of hydroxyl radicals, electrodexification, cathodic reduction, electroadsorption, electric floatation, electrocoagulation and other functions are used in electric Fenton equipment, and the treatment efficiency is higher.
Electric Fenton Power Supply:
Electric Fenton technology is a commonly used advanced oxidation technology that is widely used in the field of wastewater treatment. It rapidly degrades organic pollutants by introducing hydrogen peroxide and iron ions to produce highly reactive hydroxide radicals. The following will introduce the working principle and application of electric Fenton wastewater treatment technology.
The working principle of electric Fenton wastewater treatment technology is based on the strong oxidizing properties of hydrogen and oxygen radicals. During the electric Fenton reaction, an active hydrogen and oxygen radical (HO), a strong oxidizing agent, is formed by adding an appropriate amount of hydrogen peroxide (H2O2) and iron ions (usually divalent or trivalent iron salts) to the wastewater. Hydroxide radicals can react with organic pollutants in wastewater and degrade them into low-molecular-weight compounds (e.g., CO2, H2O) and non-toxic and harmless substances.
In the electric Fenton reaction, hydrogen peroxide reacts with iron ions to produce hydroxide radicals, and its reaction formula is as follows:
fe2+ +h2o2 → fe3+ +ho• +oh-
The generated hydroxide radicals have a high oxidizing capacity and can directly oxidize with the organic matter in the wastewater. Hydroxide radicals react with the hydrogen atoms in the organic molecules to initiate a chain oxidation reaction, so that the organic molecules are continuously broken, so as to achieve the purpose of degrading and cleaning wastewater.
