Antibacterial protection bag for water purification equipment

Abstract

The invention discloses an antibacterial protection bag for water purification equipment. The antibacterial protection bag comprises a bag body on which an antibacterial agent is immobilized, wherein the bag body is made from textile fibers of cotton or viscose; the antibacterial agent is metal ions or nanometal particles; metal is silver, copper or zinc. The antibacterial protection bag adopts composite porous fiber materials as base bodies and has excellent characteristics of being good in mechanical property, safe, environment-friendly and the like, and raw materials are easily available; the fiber materials as the base bodies are subjected to silver loading treatment through a unique process, so that the fiber materials have excellent, wide-spectrum and lasting antibacterial effects; the antibacterial fiber materials are made into various forms of sleeve parts which directly sleeve various water purification filter elements; when the sleeve parts are cooperatively used with the water purification filter elements, the antibacterial and bacteriostatic effects can be achieved through contact or slow release of ultralow-concentration metal ions, the growth of microorganisms can be lastingly and effectively inhibited, and the problem of secondary pollution caused by water purification filter element materials can be avoided.

Description

[0001] technical field [0002] The invention relates to the technical field of water purification, in particular to an antibacterial protective bag used for water purification equipment. Background technique [0003] In recent years, due to serious environmental pollution, especially water pollution, the water purification industry has developed rapidly. It is estimated that in the next five years, the market size of the water purification industry will reach 400 billion yuan. However, the problem of secondary pollution of water purifiers has always been a serious problem in the industry. It has been exposed in the media for a long time, and so far, this problem has not been better resolved. The secondary pollution of the water purifier is mainly manifested in the fact that many microorganisms are blocked, deposited, grown and polluted the filter material on the surface of the filter material, pipes, containers, etc., which greatly reduces the efficiency and life of the me...

Problems solved by technology

However, the problem of secondary pollution of water purifiers has always been a serious problem in the industry. It has been exposed in the media for a long time, and so far, this problem has not been better resolved.

The secondary pollution of the water purifier is mainly manifested in the fact that many microorganisms are blocked, deposited, grown and polluted the filter material on the surface of the filter material, pipes, containers, etc., which greatly reduces the efficiency and life of the membrane, and also brings water purification bacteria. Potential safety hazards of total bacterial colony exceeding the standard

At the same time, if the microorganisms deposited in the filter material contain blue-green algae, the potential harm is even greater, because the metabolism of blue-green bacteria may produce carcinogenic algal toxins (such as: microcystin, cyanotoxin, detoxification Toxins, saxitoxins), these toxins are composed of several amino acids, very small (<1nm), basically can pass through most of the filter materials into the effluent, at the same time, they can withstand high temperatures (up to 300 degrees), common The method of boiling water cannot be effectively removed, which will bring great harm to the human body

In addition, these microorganisms can quickly decompose the filtered organic matter and even the organic membrane material itself, producing an unpleasant smell; the organic membrane material is often easily broken after being attacked by microorganisms locally, thus losing the purification function of the filter membrane material, reducing the service life, and hiding huge security risk

[0004] In order to avoid secondary pollution of water purifiers, the current common method is to use powerful and expensive disinfectants to disinfect the filter material or to filter the membrane material Backwashing, but these methods have many disadvantages

Disinfectants often destroy organic membrane materials and may cause corrosion to plastic components. Residual disinfectants may also pollute purified water; backwashing operations are often time-consuming and need to be driven by external forces, and not all water purification devices filter materials are suitable for backwashing operations

In addition, some filter element materials with bactericidal effect are now used in water purification devices, such as silver-loaded activated carbon rods; on the one hand, this is not applicable to all water purification devices, and the bactericidal effect may be partial , may not cover the entire water purification device; on the other hand, if such accessories are forcibly added to the existing water purification device, it is inevitable that the structure and structure of the existing device need to be modified, which will bring unnecessary troubles. Extend the development cycle of new products
