preparation example Construction

[0027] The preparation of nano-carbon crystals refers to the patent CN2015107503345. The prepared nano-carbon crystals have a spherical shape, the C content is 99-100%, and the lattice spacing is 0.21nm; the C atoms on the surface of the nano-carbon crystals and the inner diamond phase C atoms constitute a dimer structure of C atoms, and the two carbon atoms in the dimer structure of C atoms are distributed asymmetrically; the average particle size is R, and 0<R≤10nm. Nano-carbon crystals have the advantages of fine particles, high hardness, good wear resistance, extremely high specific surface area, excellent adsorption performance, and stable physical and chemical properties.

[0028] The preparation of nanodiamondene refers to the patent CN2015107492073. The prepared nanodiamondene has a lamellar single crystal structure, and the carbon atoms in the same sheet are sp 3 Orbital hybrid carbon bond connection, carbon atoms between layers are sp 2 Hybrid carbon bonds, C conten...

Abstract

The invention discloses a ceramic filter core containing nanometer carbon crystal and nanometer diamond alkene blends, and belongs to the field of water treatment equipment. The ceramic filtering core is sequentially provided with a support layer, a filtering layer, a first separation layer and a second separation layer from inside to outside. The invention also discloses a preparation method of the ceramic filtering core. According to the ceramic filter core, due to the high surface activity of nanometer diamond alkene and nanometer carbon crystals, the specific functional group or particle adsorption treatment can be performed; after silver nitrate is added; silver ions can be adsorbed on the surfaces of the nanometer diamond alkene and the nanometer carbon crystals in the mixed treatment process; in the later-stage sterilization process, the continuous action can be realized; the brining away from the ceramic filter core due to dissolution by water molecules cannot be caused, so that the long-time degerming effect is achieved.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to a ceramic filter core containing a blend of nano-carbon crystals and nano-diamondene. Background technique [0002] Pollutants in domestic water mainly include particulate matter, microorganisms, organic dissolved substances and heavy metal ions. Although tap water can remove a large number of the above-mentioned pollutants during the treatment process, some organic substances will still remain. These organic substances combine with free chlorine to form carcinogenic organic chlorine substances such as chloroform. In addition, the secondary water supply in the city and the aging of the pipe network will lead to secondary pollution of tap water, which will still bring in the above pollutants, thus affecting the quality of drinking water. Therefore, it is necessary to install drinking water purification in individual households Devices to improve the quality of...
