Organic pollutant degradation apparatus

The invention discloses an organic pollutant degradation apparatus. The apparatus comprises a liquid container; an ultrasonic wave assembly; and a reaction tube, wherein the ultrasonic wave assembly can transmit ultrasonic waves into the liquid container, the reaction tube is coiled around an axis and is in a spiral shape, and can be rotated around the axis, and at least part of the reaction tubeis immersed in the liquid container. The reaction tube is rotated continuously, during the rotation process, a liquid in the tube is continuously stretched into a film under the action of centrifugalforce, an enlarged liquid area provides an oxidizing gas to continue to be miscible with the liquid in the reaction tube, gas-liquid miscibility is strengthened by the process of forming a slug flow in the reaction tube, an ultrasonic cavitation oxidation effect is easy to form, and the effect is repeatedly carried out in the rotated reaction tube, so that the continuous, sufficient and uniform degradation of organic matte
