description The present invention discloses a biological deodorization filler and a preparation method thereof, wherein the biological deodorization filler is prepared from 60-70 parts by weight of deeply dewatered sludge, 20-30 parts by weight of clay, 10-20 parts by weight of pottery sand, and 1-5 parts by weight of an additive. The specific preparation method comprises: S1, uniformly mixing deeply dewatered sludge, clay, pottery sand and an additive, and granulating through a granulator; S2, drying the particles obtained through the granulating at a room temperature or in an environment with the temperature of not higher than 80 DEG C until the water content is 40-50%; S3, conveying the dried particles into an anaerobic high-temperature carbonization furnace, and carrying out carbonization for 30-45 min at a temperature of 850-900 DEG C under a pressure of 3-4 Mpa; S4, discharging the carbonized particles out of the furnace, and cooling to a room temperature; and S5, screening the cooled particles, separating the brok
