[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.
[0020] The filter element includes nano-copper-carbon composite material particles and cellulose, which is formed by bonding nano-copper-carbon composite material particles with a particle size of 20-50nm and cellulose. The weight ratio of nano-copper-carbon composite material particles and cellulose is ( 8~12): 1, preferably 10: 1, the filter element is a cylinder with a height of 5cm or more. The nano-copper-carbon composite material is the material disclosed in the patent application US2012 / 0021222.
[0021] The preparation method of the filter element is as follows: take nano-copper-carbon composite material particles and cellulose as raw materials, mix them uniformly in a weight ratio of 10: 1, and fill the uniformly ...
