Ozone, ultraviolet light and ultrasonic wave synergistic wastewater treatment device and working method thereof

Abstract

The invention discloses an ozone, ultraviolet light and ultrasonic wave synergistic wastewater treatment device and a working method thereof. The ozone, ultraviolet light and ultrasonic wave synergistic wastewater treatment device comprises a reactor provided with an ultrasonic vibrator and an ultraviolet lamp, a controller with an ultrasonic generator having an ultrasonic frequency adjusting function and an ozone generator, a water tank and a power supply; a reactor is connected with the controller through a pipeline and a circuit; the ultrasonic generator is connected with the ultrasonic vibrator through a circuit; the water tank is connected with the controller through a pipeline; the power supply is connected with the controller through a circuit. The working method comprises the following steps: liquid injection, wastewater treatment, gas and liquid circulation, as well as sampling and monitoring. The wastewater treatment device and the working method thereof have the advantages that three oxidation treatment technologies, namely ozone, ultraviolet light and ultrasonic waves are synergistically synthesized in one reactor, so that ultrasonic waves of different frequencies and ultrasonic light of different frequencies can be supplied in the reactor, and poisonous and harmful wastewater can be cyclically treated by the wastewater treatment device till a satisfied optimal effect is achieved.

Description

(1) Technical field: [0001] The invention relates to a treatment device and working method for toxic and harmful waste water, in particular to a waste water treatment device and working method for the synergistic effect of ozone, ultraviolet light and ultrasonic waves. (two) background technology: [0002] With the development of science and technology, more and more organic matter is used in the process of industrial production, and the waste water produced has the characteristics of high toxicity, complex composition and difficult degradation. If these wastes are discharged directly to the outside without treatment, they will It poses a great threat to the environment and human health. The treatment of refractory toxic and hazardous waste has attracted attention both at home and abroad. Ozone is a highly oxidizing oxidizing agent, which has the functions of sterilization, disinfection, and color removal. It has strong oxidizing ability and fast processing speed. Ultravio...

AI Technical Summary

Problems solved by technology

[0003] With the complexity of the components of industrial production waste liquid, the traditional physical, chemical and biochemical secondary treatment process has been unable to completely remove toxic and harmful components.

Moreover, the cost of ozone is relatively high. In the gas-liquid transmission contact, the propagation rate of ozone to the liquid is slow, and bubbles are generated in the liquid, which deteriorates the propagation of ozone in water. In general, the solubility of ozone in liquid is relatively low. Low, affecting the oxidation of ozone
