The invention discloses a solar
photocatalytic degradation device, belongs to the technical field of
sewage treatment and particularly relates to a device which solves the problems that a
sewage treatment device is high in
energy consumption, high in price and prone to secondary
pollution by using a modified photocatalyst responsive to
ultraviolet visible light and taking
sunlight as a
light source to drive reactions to degrade pollutants. The device mainly comprises reaction tanks, hollow pipes, air ejecting pipes, an
air pump, a transparent stair-shaped
photocatalytic reaction chute, circular arc baffles, a water conveying
pipe, a water pump, a water collecting
pool and a
solar cell panel. The reaction tanks are used for providing sites for homogenizing and
processing sewage, the hollow pipes are used for carrying
ultraviolet visible light modulator tubes, the air ejecting pipes and the
air pump are used for aerating the reaction tanks, the transparent stair-shaped
photocatalytic reaction chute is used for providing a
photocatalytic degradation site, the circular arc baffles are used for homogenizing and slowing down a sewage solution, the water conveying
pipe and the water pump are used for conveying the sewage in the water collecting
pool into the reaction tanks, the water collecting
pool is used for collecting degraded sewage, and the
solar cell panel is used for storing
electric energy. The
sunlight is mainly used, and the device has the advantages of being clean, efficient, free of secondary
pollution, controllable in reaction
atmosphere, high in
light source utilization rate and the like.
