Embodiment Construction

[0039] Below in conjunction with accompanying drawing this invention will be further described.

[0040] Discharge electrode 1, low-voltage electrode 2, catalyst 3 and aeration head 8 are installed in the closed reactor 4, and the output voltage of high-voltage power supply 5 is introduced on the discharge electrode 1 and low-voltage electrode 2 through the power lead 9, and the reaction is carried out by the water pump 10. A certain amount of organic dye wastewater is filled inside the device 4, and the organic dye wastewater is aerated through the air pump 6 and the aeration head 8. The catalyst 3 exists in the reactor 4 in the form of powder or attached to the surface of the carrier and the electrode. In this way, a three-phase mixed state of gas, liquid and solid is formed inside the reactor 4 . Under the condition of gas, liquid and solid three-phase mixing inside the reactor 4, when the high-voltage power supply 5 outputs high voltage, by adjusting the distance between t...

Abstract

The invention discloses a method and apparatus for treating organic wastewater by pulse discharge plasma inducting photocatalysis, wherein an electrode construction with strong uneven electric fields and narrow impulse high voltage supply power supply are employed to form impulse corona flow optical electric discharge in the water, the flow light and sparks produced by the electrical discharge are used as luminous source to induce the optical catalytic activity of the semiconductor catalyst in the electric field.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution control. In particular, it relates to a pulse discharge plasma-induced photocatalytic treatment method and device for organic wastewater. Background technique [0002] With the rapid development of industry and the increase of the world's population, the demand for fresh water is increasing rapidly, resulting in an increase in the amount of industrial sewage and domestic sewage. The sewage contains a large amount of organic matter and heavy metals. If it is discharged directly without treatment, it will bring serious pollution to the environment and affect the survival of human beings and the sustainable development of industry and agriculture. At present, the commonly used wastewater treatment is biochemical method, supplemented by some physical and chemical methods, such as electrolysis, air flotation, absorption and so on. However, the effects of these methods on the treatment...
