Problems solved by technology

[0004] The problem with the existing filter element is that it needs to be replaced frequently. After a long time, a large number of bacteria are attached to the filter element, which may cause secondary pollution to the water. At the same time, the existing filter element has poor filtering ability for some bacteria.

specific Embodiment 1

[0028] Specific embodiment 1: a kind of drinking water filter core, described filter core comprises skeleton layer, fiber layer, and described skeleton layer is formed into porous structure by being made of ceramic material, and described fiber layer is silicon nitride ceramic fiber and titanium A mixed fiber of alloy fiber, wherein titanium alloy fiber accounts for 20%, and a filter membrane is attached to the fiber layer, and the filter membrane is formed by spinning poly-β-hydroxybutyric acid. The thickness is 20 μm. The poly-β-hydroxybutyric acid is modified by grafting β-hydroxyethyl methacrylate.

[0029] The preparation method of described poly-beta-hydroxybutyric acid is as follows:

[0030] Step 1: get the bacillus strain;

[0031] Step 2: Cultivate the bacillus species in a nitrogen-free medium for 60 hours;

[0032] Step 3: Dilute and inoculate the above culture solution on a plate by 20-fold dilution method, culture at 25°C-29°C for 3 hours, and pick a single co...

Description

technical field [0001] The invention relates to a water filter element. Background technique [0002] Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform in-depth filtration and purification of water quality according to the requirements for water use. The water purifier usually referred to generally refers to a small purifier for household use. [0003] The core of its technology is the filter membrane in the filter element device. At present, the main technology comes from ultrafiltration membrane and RO reverse osmosis membrane. The water purifier can effectively filter out rust, sand, colloid and other chemicals such as residual chlorine, smell, color, and pesticides in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water. The application of water purification technology in the field of drinking water will make the phenomenon of "acclimatization" soon a thing o...
