Sludge biological drying conditioner and preparation method thereof

The invention relates to the technical field of sludge recycling, and in particular, relates to a sludge biological drying conditioner and a preparation method thereof. The sludge biological drying conditioner comprises a porous biochar material and a high-activity enzyme, and the high-activity enzyme is loaded on the porous biochar material with stearic acid as a fixing agent; and the high-activity enzyme can directionally catalyze and degrade macromolecular degradation-resistant substances in sludge, and the phase transition temperature of the stearic acid is 65-75 DEG C. Stearic acid absorbing enough heat in the early stage is subjected to phase change in the middle and later stages of sludge biological drying high temperature, the high-activity enzyme is released to catalyze the macromolecular degradation-resistant substances, that is, the degradation-resistant substances are decomposed, organic matters are continuously provided for a biological drying system in which a large amount of simple organic matt
