Abstract

The invention discloses a magnetically assisted photocatalysis sewage treatment device which comprises a motor, a reactor, a magnetic coil, a rotating device, a high-gradient magnetic separator and a magnetic flocculant reflex pump, wherein the reactor is internally provided with the rotating device and an ultraviolet lamp group; the rotating device is provided with a magnet strip group and a mud scraping board. According to the invention, sewage enters from the water inlet pipe of the reactor, and a magnetic photocatalyst is reacted with the sewage under the irradiation of ultraviolet light through the stirring of magnet strips and magnetic field action, so that the effect of sewage treatment is achieved; pollutants contained in the sewage are effectively removed under the action of a magnetic field, photocatalysis, flocculation, and the like; the magnetic photocatalyst can also be recovered, so that wide market application prospect is achieved. The magnetically assisted photocatalysis sewage treatment device disclosed by the invention has the characteristics of compact structure, small occupied area, low operating cost, good treatment effect, and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a treatment device for magnetically assisted photocatalytic sewage. Background technique [0002] In recent years, with the development of science and technology and the comprehensive utilization of interdisciplinary, it has become a new water treatment technology to degrade pollutants in water (especially high-concentration and low-concentration pollutants) through photocatalytic oxidation technology. It can be used alone or in combination with other water treatment technologies. It has low energy consumption, easy operation, no secondary pollution and low cost in the degradation process. It is a very promising technology. As the main equipment of photocatalytic reaction, photocatalytic reactor determines the performance of catalyst activity and the utilization of light, which will also directly affect the efficiency of photocatalytic reaction. The design a...
