Abstract

The invention discloses a wastewater treatment apparatus utilizing photocatalysis to degrade organic pollutants. The apparatus comprises a barrel, the lower part of the barrel is provided with a water inlet, the upper part of the barrel is provided with a water outlet, a support plate is arranged in the barrel, multiple base plates are arranged between the top of the barrel and the support plate, each base plate is provided with a UV source and is covered by a photocatalyst film, and a magnetic adsorption device and a magnetic photocatalyst are arranged between the support plate and the bottom of the barrel. The provided wastewater treatment apparatus overcomes the shortages that in the prior art, a photocatalyst is easily deactivated, gets agglomerated easily, and is hard to recover. The apparatus has the advantages that the photocatalytic reactions are carried out more fully, the photocatalyst agglomeration is avoided, and the photocatalyst is easy to recover.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a wastewater treatment device for degrading organic pollutants by photocatalysis. Background technique [0002] Industrial sewage contains a large amount of toxic and harmful substances, including a variety of halogenated organic compounds, especially in dye wastewater, which contains a large number of organic pollutants, which are difficult to eliminate by biological treatment technology. [0003] Photocatalytic oxidation technology is the use of photogenerated strong oxidants to oxidize organic pollutants into H 2 O.CO 2 Such as small molecules, especially for refractory organic matter has a good oxidative decomposition. Photocatalytic oxidation technology has the advantages of mild reaction conditions, non-toxic and harmless to the human body and the environment, and a wide range of applications. It is a very promising method for organic wastewater t...
