Abstract

Disclosed is an ultrasonic and hydrodynamic cavitation combined treatment device for organic wastewater. The device comprises a rotor and a stator; a cavitation cavity is formed in the stator, ultrasonic transducers are distributed on the stator and connected with an ultrasonic generator, and the stator is provided with a water inlet and a water outlet; the rotor is installed in the stator, one end of the rotor protrudes out of the stator, the protruding end is connected with a transmission device, the rotor is provided with a cavitation disk, and the cavitation disk is located in the cavitation cavity of the stator and provided with blind holes. The device has the advantages that by adopting the combined functions of ultrasonic cavitation and hydrodynamic cavitation, the organic wastewater is treated, chemical reagents are not used, and therefore secondary pollution cannot be caused; the hydraulic cavitation is rotary, more cavitation bubbles can be generated through the rotation of the rotor and the blind holes, the oxidation effect is more obvious, the advantages of simple hydrodynamic cavitation structure and high ultrasonic cavitation collapse strength are integrated, the mechanical structure is simple, the efficiency of degrading the organic wastewater is high, and the efficiency is high.

Description

technical field [0001] The invention relates to a device for treating organic wastewater, belonging to the technical field of organic wastewater treatment. Background technique [0002] With the continuous development of industry, more and more organic pollutants in industrial wastewater are difficult to degrade. After traditional biochemical process treatment, some organic pollutants that are difficult to degrade still exist in the treated sewage. Therefore, it is necessary to degrade the sewage. for further processing. With the continuous development of science and technology, advanced oxidation technology came into being. Advanced oxidation technology produces a large number of highly active free radicals through certain methods, which have extremely strong oxidizing properties. Cavitation is one of them, including hydraulic cavitation, acoustic cavitation, optical cavitation, and particle cavitation. [0003] Cavitation has three effects, including mechanical, thermal...
