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.

Abstract

The invention relates to a ultrasonic oxidization sewage treatment process which is aimed at solving the problem of unsatisfactory treatment effects to COD, BOD, SS, N, P, chromaticity and various hard-degradable organics in the conventional sewage treatment methods, the process according to the invention comprises the steps of, (1) water pretreatment, (2) subjecting the pretreated water to ultrasonic treatment, (3) subjecting the treated water to post-treatment, high-grade oxidation treatment can be added to each or any one of the steps.

Description

Technical field: [0001] The invention relates to a sewage treatment method, in particular to a sewage treatment method using ultrasonic wave and advanced oxidation treatment. Background technique: [0002] With the rapid development of fine chemical and pharmaceutical industries as well as printing and dyeing industries, the treatment of some high-concentration, refractory, toxic and harmful organic wastewater has always been a difficult problem for environmental protection workers. At the same time, the micro-pollution of drinking water is also directly related to the health of human drinking water. . At the same time, with the improvement of living standards, people's awareness of environmental protection continues to strengthen, and they pay more and more attention to the migration and changes of refractory organic matter in the environment. However, the treatment of high-concentration refractory organic pollutants is always a difficulty in wastewater treatment. , are di...
