Embodiment 1
[0034] A combination of ultrasonic and photocatalytic oxidation is used. as attached figure 2 As shown, the ultraviolet lamp 1 adopts a broad-spectrum UV lamp, the lamp tube is covered with a quartz tube, and the quartz tube is coated with a catalyst carrier, and the catalyst 2 used is TiO 2 .UV lamp placed in ultrasonic generator.
Embodiment 2
[0036] Ultrasonic wave and ultraviolet light are used to assist Fenton's reagent (Fenton) to jointly treat sewage. The ultraviolet light adopts a broad-spectrum UV lamp with a wavelength of 20O-280nm, and Fenton reagent is added to the reactor.
Embodiment 3
[0038] Using ultrasound and ozone / ultraviolet light (UV / O 3 )Combine. The ultraviolet lamp adopts broad-spectrum UV lamp. Dosing ozone in the reactor, the ozone concentration is mg / l.
