What are the advantages of electric Fenton method compared with traditional Fenton method in sewage treatment?

The outstanding characteristics of the oxidation process of electric Fenton equipment are: high COD removal efficiency, simple operation and management, extensive pollutant removal, and no increase in salt content of wastewater.

The specific advantages of electric Fenton equipment are as follows:

1. reduces the processing cost. Because the electro-Fenton method can generate H2O2 in situ without adding a small amount of chemicals, it can generate H2O2 and Fe2+ in situ, which greatly reduces the treatment cost.

2. The treatment effect is better. Because of the addition of current, the oxidation is stronger and the reaction is more thorough.

3. The reaction continues. Electro-Fenton method can effectively degrade organic matter in wastewater for a long time. Fe2+ and H2O2 in the solution are constantly produced at a certain rate, and the organic matter is degraded more thoroughly.

4. The treatment efficiency is high. The reason why the electro-Fenton process is more effective than the traditional Fenton process is that it has the following factors: anodic oxidation, photoradical oxidation and electro-adsorption.

5. The secondary pollution degree is small. Fe ~ (2+) can be regenerated and recycled by cathode, which will not cause the pollution of Fe (OH) ~ (3) sludge, thus reducing the output of iron sludge, with almost no secondary pollution and simple subsequent treatment.

Field application of electric Fenton equipment

6. Flexible process. Electro-Fenton method can usually be combined with other methods for wastewater pretreatment or advanced treatment, and the process is flexible.

7. High degree of automation. The processing equipment is relatively simple, and the main parameters of electrochemical operation process are current or voltage, so it is easy to realize automatic program control.

8. Advantages of equipment quality. The electric Fenton oxidation equipment occupies a small area, which effectively avoids the risks of reagents in transportation, storage or treatment.
