Number is more than 50,000,000.There are 1.9 hundred million people ill every year in China, 60,000 people die from the disease that water pollution causes, and Chinese Government is
Drinking water safety is listed in scientific and technological key special subjects.
Use cost is cheap, the water purification catridge of low-carbon (LC) is farthest improving the research side that drinking water quality is filter core
To.Filter core mainly has following a few classes at present：Active carbon filter core, with extremely strong suction-operated, typically adsorbable is more than 10 μm
Particle；PP melt-blown filter, filter core accuracy rating 0.5-100 μm, the impurity of different-grain diameter can be retained；Ceramic element, is a kind of new
Type environment-friendly filter element, filtering accuracy reach 0.1 μm, for removing the solid particle in the liquid in water, plating solution, running water.Although
These filter cores have a certain effect to purification of water quality, but the process for microorganism in water, and filter core also has very big development space.
Content of the invention
For the problems referred to above, it is an object of the invention to provide a kind of antibacterial filter core and its preparation method and application, should
