Embodiment Construction
[0030]Discharge electrode 1, low-voltage electrode 2, insulating medium 3, aeration head 8 and catalyst are installed in the closed reactor 4, and the output voltage of alternating high-voltage power supply 5 is introduced to the discharge electrode 1 and low-voltage electrode 2 through the power lead 9, A certain amount of organic dye wastewater is filled inside the reactor 4 through the water pump 10, and the organic dye wastewater is aerated through the air pump 6 and the aeration head 8. The catalyst is powder or attached to the carrier, the electrode and the surface film of the insulating medium. The form exists in the reactor 4, so that a three-phase mixed state of gas, liquid and solid is formed inside the reactor 4. Under the gas, liquid and solid three-phase mixing conditions inside the reactor 4, when the alternating high voltage power supply 5 outputs high voltage, the distance between the discharge electrode 1 and the low voltage electrode 2 (discharge plasma area) ...
