[0002] With the rapid development of my country's economy and the accelerated pace of urbanization, as many as 70% of the country's rivers and lakes have been affected. Water pollution mainly comes from industrial production. Currently, the most widely used method for wastewater treatment is biological treatment, which has the characteristics of high removal efficiency and low operating cost.

[0003] The traditional Fenton method is a deep oxidation technology, which utilizes the chain reaction between Fe and H to catalyze the generation of ·OH free radicals. The ·OH free radicals have strong oxidizing properties and can oxidize various toxic and difficult-to-degrade organic compounds to achieve the purpose of removing pollutants.

[0004] However, the traditional Fenton process is labor-intensive. The catalyst ferrous sulfate must be added in solid form, and the ferrous sulfate contains about 20% iron, which greatly increases the intensity of sludge treatment compared to the 11% iron content of polyferric sulfate. The catalyst ferrous sulfate is also corrosive and needs to be added continuously, which increases costs and produces unnecessary pollution. Utility Model Content
