technical field

Background technique

With the development of science and technology and interdisciplinary comprehensive utilization, it has become a new water treatment technology to degrade pollutants in water (especially high and low concentration pollutants) through photocatalytic oxidation technology. It can be used alone or in combination with other water treatment technologies. It is a promising technology with low energy consumption, easy operation, no secondary pollution and low cost in the degradation process. Due to the research and development of nano-magnetic photocatalysts, the effect and efficiency of photomagnetic reactors on sewage treatment are improved. However, since the recovery of the magnetic photocatalyst is a technical problem, the magnetic photocatalyst contained in the sludge is likely to cause secondary pollution, which affects the practical application of this technology.

The disclosed patented optomagnetic sewage treatment device and method (CN 101618918A), this device has a low utilization rate of ultraviolet light, and has a large footprint and a complex structure. In the published patent, a photomagnetic sewage treatment device (CN 102942283A), the uneven distribution of the magnetic field in this device makes it easy for the magnetic photocatalyst to not be evenly distributed in the sewage, so this device has low utilization rate of ultraviolet light and low catalyst efficiency. The disadvantages are large consumption, low catalyst recovery rate and high energy consumption.
