The present invention discloses a bacteriostatic and antibacterial ceramic filter element and a preparation method therefor. The bacteriostatic and antibacterial ceramic filter element is mainly prepared from glauconite, bryozoatum, bentonite, nano white metal charcoal, rice husk powder, razor king shell powder, limonite, sodium bicarbonate, acrylic emulsion, cane molasses, palm fibers, corn flour, phenolic resin, epoxy soybean oil, beeswax, and bacteriostatic additives. The ceramic filter element disclosed by the invention uses glauconite and bryozoatum as the main raw material; the raw materials such as nano white metal charcoal, rice husk powder, razor king shell powder, limonite and the like are added to ensure good filtering performance of the ceramic filter element, so that hazardous substances such as heavy metals and the like can be effectively adsorbed, and chemical stability and good water resistance can be achieved; hokutolite and crystal gravel contained in the antibacterial additives can release a great number of negative ions to exert good bactericidal antimicrobial effect; and natural manganese sand, nano silver carbon molecular sieve, and nano-zinc oxide contained in the antibacterial additives interact with each other to achieve good adsorption filtration performance, and good bactericidal properties.
