Background technique

As a selective oxidizing agent, ozone has traditionally been mainly used in water treatment. However, the cost of ozone is as high as other oxidants; and the transfer rate of ozone from gas phase to liquid phase in traditional gas-liquid contact equipment such as bubble tower is low, resulting in low utilization rate of ozone and low mineralization effect in wastewater treatment process. Difference. At present, the application of new reactors in the ozonation degradation process has gradually become a trend.

As a new pollution control technology, ultrasonic technology is attracting more and more attention. It integrates advanced oxidation, incineration and supercritical oxidation. It has the advantages of fast degradation, simple and convenient operation, and no secondary pollution. It has shown great potential in the treatment of toxic, harmful and refractory organic wastewater. However, the use of ultrasonic technology to treat organic wastewater is limited due to its poor degradation effect.
