Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] see figure 1 , a solar photocatalytic degradation sewage system, including a substrate 2 installed on the sloping roof of the factory building 1, and at least one layer of photocatalytic film layer 3 arranged on the upper surface of the substrate, and a delivery pipeline 4 for transporting sewage. The delivery pipeline is provided with Sewage is sprayed onto the water distributor spray nozzle 5 on the photocatalytic film layer, and the sewage sprayed onto the photocatalytic film layer by the water distributor spray nozzle forms a layer of liquid film, the thickness of which is between 100 microns and 500 microns. During specific implementation, the substrate is tiled on the roof of a factory building or a house with a glass plate, so that the substrate can form a certain angle to better receive sunlight, and the delivery pipeline is conn...

Abstract

The invention relates to the technical field of sewage treatment and particularly relates to a solar photo-catalytic sewage degradation system. The system comprises a base plate, at least one photo-catalytic film layer arranged on the upper surface of the base plate, and a conveying pipeline for conveying sewage, wherein the conveying pipeline is provided with a water distributor spray nozzle for spraying the sewage on the photo-catalytic film layer. By arranging the photo-catalytic film layer on the base plate, a photo-catalytic degradation reactor is formed to absorb solar energy to generate micro-current so that organic macromolecular substances in the sewage can be degraded in a photo-catalytic manner, and thus the aim of sewage treatment is realized; the system disclosed by the invention is free of energy consumption, high in sewage treatment efficiency and low in emission of BOD and COD.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a solar photocatalytic degradation sewage system. Background technique [0002] Most of the current research focuses on the study of TiO 2 In terms of the properties of the photocatalyst itself, such as improving the photocatalytic efficiency, doping makes the response bandwidth red shift, etc. In addition, in the application of household air pollution control, photocatalysts with TiO2 as the main component and small photocatalyst formaldehyde digesters are widely used. But in industry, large TiO 2 There are few applications of photocatalysts. Contents of the invention [0003] Aiming at the above technical problems, the present invention provides a solar photocatalytic degradation sewage system, which forms a photocatalytic degradation reactor by arranging a photocatalytic thin film layer on the substrate, absorbs solar energy to generate microcurrent, and photocat...
