High-efficiency and multifunctional sludge conditioner and preparation method thereof

A high-efficiency and multifunctional sludge conditioner and a preparation method thereof is disclosed. The preparation method includes: soaking and adsorbing bacterial cellulose in an alkaline solution, and then taking out the bacterial cellulose to carbonize and activate the same at 380-480° C. and in a nitrogen atmosphere to obtain pretreated bacterial cellulose; and dispersing the pretreated bacterial cellulose in water, adding with an acrylamide monomer and an initiator for in-situ polymerization, and successively subjecting a reaction product to centrifugal separation, drying and crushing to obtain the high-efficiency and multifunctional sludge conditioner. In the present disclosure, the high-efficiency and multifunctional sludge conditioner only has a good flocculation sedimentation effect on the sludge, but also has a good adsorption effect on heavy metals in the water, thereby reducing the moisture content of the sludge and simultaneously reducing the content of the heavy metals and other harmful substances in the water body.
