Description

technical field [0001] The invention relates to a device for synergistically treating sewage with on-line broadband ultrasonic waves and ozone, and belongs to the technical field of sewage treatment equipment. Background technique [0002] In recent years, with the rise of sonochemistry, power ultrasound has been applied as an emerging means of sewage treatment. Its degradation conditions are mild, its degradation rate is fast, and it has a wide range of applications, especially for the degradation of organic matter in industrial wastewater. , the treatment of organic matter is more direct, and there is no secondary pollution. [0003] The degradation of organic sewage by ultrasonic waves is mainly due to its acoustic cavitation effect. That is, under the action of relatively large sound intensity, the cavitation bubble rapidly expands in the negative pressure phase of the sound wave, and then is rapidly compressed to collapse under the action of the positive pressure phase...

Problems solved by technology

Therefore, it is impractical to select the optimal frequency in a targeted manner, or in order to increase the frequency points, it will result in a large number of types and quantities of transducers, and the cost is too high, making it difficult to realize industrialization
