Inner light source ball string type photocatalysis water purifying tank

Abstract

The invention relates to an inner light source ball string type photocatalysis water purifying tank and belongs to the technical field of water environment protection. The inner light source ball string type photocatalysis water purifying tank comprises a water permeable tank capable of adjusting flow of passing water, multiple purifying balls, side light fibers, a power supply device and an ultraviolet generator, the side light fibers are positioned in the water permeable tank, folded to be wavy to be fixedly connected with the same and electrically connected with the ultraviolet generator, the ultraviolet generator is electrically connected with the power supply device, the purifying balls are fixedly arranged on the side light fiber, and each purifying ball is coated with a nanocrystal titanium dioxide film. Ultraviolet is guided into the purifying balls through the side light fibers and directly radiates the surface of a photocatalysis film in a near-distance manner, so that light source utilization rate is high, radiation intensity is high, and photocatalysis efficiency is improved greatly. Each purifying ball is of a hollow structure, so that specific surface area is increased, the side light fibers penetrate the purifying balls from the middles, and ultraviolet illumination is free of dead angle, so that photodegradation reaction efficiency of the photocatalysis film and pollutants in water is improved to a certain degree.

Description

technical field [0001] The invention relates to an internal light source ball string type photocatalytic water purification box, which belongs to the technical field of water environment protection. Background technique [0002] In recent years, with the rapid development of my country's industrialization and the further improvement of agricultural intensification, the produced industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of untreated or incompletely treated sewage is discharged into rivers, lakes and other water bodies through river and canal systems at all levels, resulting in the overall deterioration of the water quality of rivers and lakes. An important measure of protection. At present, there are more and more forms and sources of pollutants, and the types of pollutants dissolved or suspended in water are becoming more and more diverse and complex. In the traditional biological purifica...
