Problems solved by technology

In the fixed bed photocatalytic reactor, the contact area between the catalyst and the organic matter is small, which limits the progress of the photocatalytic reaction; while in the fluidized bed reactor, the catalyst is too dispersed in the solution, which is not conducive to recovery.

Abstract

The invention relates to the technical field of photo-catalytic oxidation, and particularly relates to a device for treating organic wastewater by photocatalysis. The device for treating the organic wastewater by photocatalysis comprises a box body, ultraviolet lamps and foamed ceramics; the ultraviolet lamps are arranged in the box body; the foamed ceramics are filled into and arranged in the boxbody; a water inlet and a water outlet which are both communicated with the interior of the box body are arranged on the box body; and catalysts used for being subjected to oxidizing reactions with organic matters in the wastewater under illumination of the ultraviolet lamps are formed on the surface of the foamed ceramics. The device for treating the organic wastewater by photocatalysis, involved in the invention, has the advantages that the structure is simple; the use is convenient; dismounting and mounting are simple and convenient; a contact area between the organic matters in the wastewater and the catalysts is relatively large; and the oxidation treatment efficiency is relatively high.

Description

technical field [0001] The invention relates to the technical field of photocatalytic oxidation, in particular to a device for photocatalytically treating organic wastewater. Background technique [0002] With the development of industry, the treatment of industrial wastewater has attracted people's attention. Compared with ordinary domestic wastewater, the composition of industrial wastewater is complex, with many harmful substances and easy to generate refractory organic matter. If ordinary biochemical treatment is used, it is difficult to achieve the expected treatment effect. And using TiO 2 Photocatalytic technology can effectively solve these problems. TiO2 has no secondary pollution, small restricted range, strong oxidation and good photocatalytic performance, showing obvious excellence in the field of industrial wastewater treatment. But TiO 2 Poor stability, easy to inactivate in the process of treating high-concentration organic wastewater, and the reusable ra...
