Photo-catalytic water purification post

Abstract

The water purifying photocatalyst column includes one middle part photocatalytic chamber, which has quartzite supporting high photocatalytic activity titania as photocatalyst, light source in the middle and guide partition board; one bearing ring below the photocatalytic chamber, one active carbon barrier layer, one porous partition plate and one water accumulating deposition cavity with water exhaust set successively below the photocatalytic chamber; one primary filtering layer, one porous partition plate and one buffering cavity with water inlet set successively above the photocatalytic chamber; and sealing thread structures on two ends. The water purifying photocatalyst column of the present invention can kill bacteria, viruses and microbes in water permanently and decompose toxic and harmful matter in water completely, and has stable performance and no pollution caused by catalyst carrier bits.

Description

technical field [0001] The invention relates to a water purification device capable of killing microorganisms, bacteria and viruses in water and effectively degrading toxic and harmful molecules, in particular to a photocatalyst water purification column. Background technique [0002] Traditional water purifiers generally use filter material filtration and ultraviolet ozone sterilization devices to purify water bodies. However, there is a problem of adsorption saturation in filter material filtration. The saturated filter material not only reduces the water permeability, but also is likely to become a hotbed for the accumulation and breeding of bacteria and viruses. In addition, the filter material does not have a strong effect on filtering water-soluble toxic and harmful molecules. Frequent replacement of the filter material will not only increase the use cost of the water purifier, but also cause inconvenience in maintenance. [0003] Water purifiers equipped with ultrav...

Problems solved by technology

However, there is a problem of adsorption saturation in filter material filtration. The saturated filter material not only reduces the water permeability, but also may become a breeding ground for bacteria and viruses to gather and breed.

In addition, the filter material is not very effective in filtering water-soluble toxic and harmful molecules.

Frequent replacement of the filter material will not only increase the cost of the water purifier, but also cause inconvenience in maintenance

[0003] Water purifiers equipped with ultraviolet ozone devices can kill bacteria, viruses and microorganisms in water to a certain extent, but these living organisms will release endotoxins after death, causing secondary pollution of water bodies

[0004] Someone has used titanium oxide loaded glass fiber as a photocatalyst to make a photocatalyst reactive water purifier (CN95244568.9). However, the glass fiber itself has a strong absorption effect on ultraviolet light, which weakens the light source utilization of the photocatalyst.

Moreover, the glass fiber is easy to break. The fragments formed by the micron-sized glass fiber used to obtain a large specific surface area are easily mixed into the water flow and difficult to separate. If it is inhaled into the human body, it will be extremely harmful to human health.
