Abstract

The invention provides a low-noise multi-frequency ultrasonic chemical reactor, and belongs to the field of degradation-resistant industrial wastewater treatment. According to the low-noise multi-frequency ultrasonic chemical reactor, mainly, multiple kinds of ultrasonic generators with different frequencies are used for generating three kinds of ultrasonic waves with different frequencies in horizontal and vertical directions to form an ultrasonic irradiation net, and through arc surface-shaped focusing, the three kinds of ultrasonic waves with the different frequencies are subjected to a compounding superposition action to achieve a cavitation effect and mechanical strength more significant than those of unidirectional single-frequency ultrasonic wave irradiation. The low-noise multi-frequency ultrasonic chemical reactor is even in ultrasonic irradiation, low in noise, high in organic matter degradation rate and high in wastewater treatment efficiency.

Description

technical field [0001] The invention belongs to an ultrasonic wastewater treatment device involved in the field of refractory industrial wastewater treatment, and in particular relates to a low-noise multi-frequency ultrasonic chemical reactor and a multi-frequency ultrasonic chemical wastewater treatment method. Background technique [0002] With the development of human production and life, a large amount of organic pollutant wastewater and dye wastewater are discharged into water bodies, and urban water pollution is becoming more and more serious. Most of the wastewater comes from industries such as soda ash, chlor-alkali, dye manufacturing, papermaking, chemical industry, paint, food and beverage, especially the refractory and high-concentration organic wastewater discharged from the chemical industry and printing and dyeing industry. The composition is complex and the concentration of organic matter is high. Processes and equipment put forward higher requirements. [0...
