Catalytic ozonation technology

Catalytic ozone oxidation technology can effectively solve the limitations of weak and selective ozone oxidation alone. By improving ozone utilization efficiency, reducing ozone dosage, enhancing mineralization effect, it achieves the feasibility of deep treatment of difficult to degrade industrial wastewater in terms of technical and economic indicators.

Based on the principle of not causing secondary pollution to industrial wastewater and achieving catalyst reuse, the current mainstream method for catalyzing ozone in industrial wastewater is heterogeneous catalytic oxidation using supported catalysts containing transition metals. The development and preparation of more stable, durable, efficient, and inexpensive catalysts is the direction of progress in this field. To further expand the application scope of catalytic ozone technology in industrial wastewater, it is possible to consider coupling catalytic ozone with biological units to improve B/C and reduce biological toxicity as the main goals of the catalytic ozone unit. By reducing the amount of ozone added, operating costs can be lowered. At the same time, the potential catalytic performance of homogeneous metal ions and specific organic compounds contained in different industrial wastewater is also worth paying attention to. Seeking in-situ homogeneous catalytic technology for waste treatment is also a new direction for the development of catalytic ozone. In addition, the organic combination and synergy of catalytic ozone and traditional water treatment units are also in line with the inevitable trend and technological requirements of upgrading and transforming industrial wastewater treatment.
