Problems solved by technology

[0004] 1. It belongs to physical filtration, and it will become a hotbed of microorganisms after a period of use. Health system experts pointed out that after about 7 days for a general ultrafiltration membrane filter element, the microbial indicators such as bacteria and algae in the water will greatly increase, and the intercepted Microorganisms will adhere to the surface of the ultrafiltration membrane to grow and multiply, which may completely block the micropores, or even completely block the inner cavity of the hollow fiber, so that the filtering effect will soon be lost. The existing technology uses repeated washing of the ultrafiltration membrane (positive flushing and recoil) to overcome, the effect is not very satisfactory, and repeated flushing will easily make consumers lose patience with this filter element, thus giving up the use of ultrafiltration membrane filter elements;
[0005] 2. High concentration of nitrite
Ultrafiltration membrane filtration technology is the best solution to deal with organic pollution, but everything has two sides. In water quality with serious organic pollution and obvious turbidity, this technology will lead to an increase in microbial indicators, which will lead to an increase in nitrite concentration. The direct manifestation is that the water quality will become salty after using the water purifier for a period of time, which not only affects the taste, but also seriously threatens human health;
[0006] 3. Under the action of large particles of impurities or running water hammer, the ultrafiltration membrane is easy to break or scratch, which affects the filtration effect, cannot effectively remove various chemical pollutants, and shortens the service life of the water purification filter element that prevents microbial growth ;
[0007] 4. The bleaching powder in the water has strong oxidative properties, and it is easy to cause serious oxidative damage to the ultrafiltration membrane at the back end

Abstract

The invention relates to a water purification filter core for preventing microbial growth, comprising an activated carbon fiber filter membrane cylinder with a hollow filter cavity, an upper sealing cover arranged on the upper end surface of the activated carbon filter membrane cylinder, and a lower end cover arranged on the lower end surface of the activated carbon filter membrane. Membrane housing, ultrafiltration membrane and activated carbon fiber filter sheet, the upper surface of the lower end cover is located on the upper part of the water outlet through hole, and a filter tube body extends to the hollow filter chamber of the activated carbon fiber filter membrane cartridge. The upper end surface of the filter tube body and the upper sealing cover There is a water inlet cavity between the lower end faces of the filter tube body, and there is a water gap between the outer wall of the filter tube body and the inner wall of the activated carbon fiber filter membrane tube. The filter cover that can prevent the Hailuo filter material from moving upward, the lower inner cavity of the filter pipe body is equipped with a filter screen that prevents the Hailuo filter material from moving downward, and the activated carbon fiber filter and the ultrafiltration membrane are arranged in sequence from bottom to top In the ultrafiltration membrane housing, the upper part of the ultrafiltration membrane housing is detachably connected to the lower end cover, and the lower part is provided with a water outlet pipe head.

Description

technical field [0001] The invention relates to a filter device, in particular to a water purification filter element for preventing microbial growth. Background technique [0002] The health and longevity of the human body largely depend on whether people can drink clean and healthy water. In recent years, due to the expansion of the industrial scale and the densification of large cities and factories due to economic growth, the problem of environmental pollution has increased greatly. serious problem of water pollution. [0003] In the field of water treatment, water purification filter elements are often connected to the water outlet of the faucet to filter water. Traditional drinking water purification filter elements generally use ultrafiltration membrane filters for filtration, mainly including linear hollow ultrafiltration membranes, ultrafiltration Membrane joint and water outlet pipe head, the two free ends of the ultrafiltration membrane are fixed on the ultrafilt...
