Sludge bagasse active carbon and preparation method thereof

The invention relates to sludge bagasse active carbon and a preparation method thereof. The sludge bagasse active carbon is prepared from sewage treatment sludge and sugar refining industrial waste bagasse. The bagasse is added into the sludge to improve the carbon content of the sludge and the adsorptive property of sludge base active carbon, so that the problem that the adsorptive property of the sludge base active carbon is poor is solved; and the sludge is subjected to heavy metal removal to improve the using safety of the sludge base active carbon. The process comprises the following steps of: carrying out heavy metal removal on the sludge by adopting a certain technical means; drying the sludge and the bagasse, and then uniformly mixing the sludge and the bagasse according to a certain proportion; adding an activating agent ZnCl2 solution with a certain concentration to carry out immersion and activation; then carrying out pyrolysis under the protection of an inert gas; and washing and drying to obtain the active carbon. According to the preparation method, the active carbon is prepared from the sludge and the bagasse, the active carbon with good adsorptive property is prepared, and the resource utilization of the two types of industrial solid wastes is achieved at the same time, so that the sludge bagasse active carbon has good economic, social and ecological benefits.
