The invention discloses a ceramic filter element with filter and purifying effects and a preparation method thereof. The ceramic filter element is prepared from the following raw materials in parts by weight: 65-78 parts of deionized water, 34-48 parts of diatomite, 26-39 parts of kaolin, 13-21 parts of medical stones, 3-6 parts of active carbon, 4-6 parts of calcium sulfate, 2-5 parts of palm fibers, 5-7 parts of zirconium oxide, 8-10 parts of silicon dioxide, 2-8 parts of magnesium oxide, 8-14 parts of polyethylene and 1-3 parts of silicon micro powder. The invention further discloses a preparation method for the ceramic filter element. The prepared ceramic filter element with filter and purifying effects is simple in production process, and is used for a long time; the palm fibers are added, so that porous performance is achieved while toughness of the filter element is improved, and the filter absorption is improved; the active carbon and the silicon micro powder are added, so that the strength and the absorption of the filter element are improved; the raw materials are simple and easily available, so that the production cost is low, the purifying efficiency is high, the corrosion resistance is good, the service life is long, harmful particles in air can be effectively adsorbed, and the using effect is good.
