Abstract:
The present invention relates to a method for manufacturing a biochar using sewage sludge and a novel purpose for a heavy metal adsorption of the biochar manufactured by the same. More specifically, the present invention relates to Pb-immobilization effect in soil contaminated by heavy metal, derived from a biochar manufactured in a specific process using sewage sludge. The biochar manufactured from sewage sludge has a function of adsorbing heavy metal in soil which is contaminated by heavy metal, and is especially effective in adsorbing lead (Pb). Therefore, the biochar can be useful as a material for improving and stabilizing soil which is contaminated by lead (Pb). Moreover, since sewage sludge which requires a delicate treatment is used as a component, the present invention is capable of providing solutions to both recycling of waste resource and prevention of environmental pollution.
