Key innovations
This technological innovation lies in the development of a highly efficient auxiliary catalyst for Fenton oxidation, which solves the pain points of non-reuse of the catalyst, difficulty in separation and secondary pollution in the traditional Fenton process.
Potential economic benefits
This technology significantly reduces operating costs and waste treatment costs by reusing catalysts and eliminating secondary pollution. The 500% improvement in degradation efficiency and the small equipment area can greatly improve processing capacity, save space, and reduce resource consumption. These advantages bring significant economic benefits and market competitiveness.
Potential climate benefits
This technology reduces potential emissions of untreated waste by improving the organic matter degradation efficiency of industrial wastewater by 500%. Catalyst reuse significantly reduces energy consumption and carbon emissions during the production of new catalysts. At the same time, complex separation steps are avoided, additional processing energy consumption is saved, and consumption of related processing materials is reduced.

Introduction to the results:

The treatment of refractory industrial organic wastewater has always been a difficult point and research hotspot in water treatment work at home and abroad. Compared with other advanced oxidation technologies, Fenton oxidation technology has the advantages of being fast and efficient, simple equipment, low cost, and low technical requirements, so it has received widespread attention from the water treatment community at home and abroad.

However, the metal salt (mostly iron salt) catalysts used in this technology are not reusable, difficult to separate and secondary environmental pollution have always been the main reasons restricting the industrial application of this technology.

By developing a high-efficiency auxiliary catalyst for Fenton oxidation, this project realizes the reuse of Fenton reaction catalysts, avoids the cumbersome catalyst separation steps in the later stage of the traditional Fenton reaction, has no secondary pollution during the treatment process, and the organic matter degradation rate is not lower than that of the traditional process and has good reproducibility, the degradation efficiency is increased by 500%, the equipment occupies a small area, is simple to operate, and has good industrial application value.
