Heterogeneous Catalytic Oxidation Tower
The heterogeneous catalytic oxidation tower uses solid catalysts combined with oxidants to generate strongly oxidizing hydroxyl radicals, efficiently degrading refractory organic matter in wastewater. With high treatment efficiency, mild reaction conditions and long-lasting catalysts, it is widely used in the treatment of refractory, high-concentration organic wastewater from the chemical, pharmaceutical, pesticide and dye industries. It is a key technical equipment for meeting discharge standards and advanced treatment.
The heterogeneous catalytic oxidation tower is the core equipment of advanced oxidation technology. By packing solid catalyst inside the tower and working synergistically with the oxidant, it generates strongly oxidizing hydroxyl radicals (·OH), which can efficiently degrade organic pollutants that are difficult to treat by conventional biological methods. It is an important technical device for treating refractory high-concentration organic wastewater.
Working principle: wastewater and oxidant enter the tower, where heterogeneous catalytic reactions occur on the surface of the solid catalyst. The oxidant is catalytically decomposed to produce strongly oxidizing active species such as hydroxyl radicals, which oxidize refractory organic matter into small molecules or directly mineralize them into carbon dioxide and water.
The equipment has strong oxidation capability and high treatment efficiency, and can treat high-concentration, refractory organic wastewater. The catalyst is in solid form, allowing long-term use and easy recovery. It operates under mild reaction conditions with low energy consumption and no secondary pollution. The equipment has a compact structure and can be modularly designed for easy expansion.
It is widely used for the treatment of refractory organic wastewater and upgrading projects in industries such as chemical, pharmaceutical, pesticide, dye and fine chemical.
