Abstract

The invention discloses a plasma synergistic ultrasonic cavitation effect waste water treatment reactor. The plasma synergistic ultrasonic cavitation effect waste water treatment reactor comprises a line-plate gas-liquid two-phase discharge reactor (1), a high-voltage pulse power supply (2), a line electrode (3), a plate electrode (4), ultrasonic generators (501, 502) and piezoelectric transducers (601, 602), wherein the high-voltage pulse power supply (2) is connected with the line electrode (3); the line electrode (3) is arranged on the top inside the line-plate gas-liquid two-phase discharge reactor (1); the plate electrode (4) is arranged at the bottom of the line-plate gas-liquid two-phase discharge reactor (1); the plate electrode (4) is connected with the ground; the two ultrasonic generators (501, 502) are connected with the two piezoelectric transducers (601, 602); and the two piezoelectric transducers (601, 602) are connected with an amplitude-change pole (7) and a connecting rod (8) respectively. Ultrasonic wave fields generated by the two sets of ultrasonic generators (501, 502) are vertical too each other, and a generated high-frequency sound field contributes to the improvements on the mechanical and cavitation effects of a low-frequency sound field.

Description

technical field [0001] The invention relates to a plasma industrial wastewater treatment reactor. Background technique [0002] With the development of industrialization, environmental and water pollution has become a global concern. There are many types of wastewater, complex components, poor biodegradability, good stability and toxicity. If this kind of wastewater is not controlled or treated, it will definitely cause serious harm to the environment and human health. The traditional conventional wastewater treatment methods have problems such as poor treatment effect, long cycle and high cost of toxic and harmful polymer organic matter. There is an urgent need to develop an economical, simple, efficient, practical and non-secondary pollution-free method that can deal with multiple pollutants. The low-temperature plasma wastewater treatment technology is an effective new wastewater treatment technology with very unique advantages that has been proven by scientific experim...
