The invention relates to a high-efficiency and novel biological carrier for a sewage biological treatment and a preparation method thereof. The biological carrier is prepared by comprising the following steps of: blending, extruding or injection-molding the following components: PP, PE, and ethylene-propylene copolymer, compatilizer, inorganic materials, plant materials, magnetic particles, and waste rubber according to a certain proportion, thus providing a biological carrier with large specific surface area, high hydrophilicity and easy hanged membrane on surfaces. The shapes of the biological carriers can be spherical, fibrous and polyhedral or powdery with various forms. The chemical or physical methods such as grinding, acid base reaction, coating on surface and the like can also be carried out to prepare the biological carrier, thus further improving the specific surface area, strengthening the adhesive ability of the biological membrane on the carrier, and improving the microorganism ...
