Abstract
A process for producing a heavy metal mediated biochar composite using silicate solidification. Hydrocharis dubia has excellent enrichment of manganese ions in sewage, and is used to treat sewage water to adsorb heavy metals such as lead, manganese and zinc contained in the sewage water into roots, stems and leaves thereof, which are pyrolysed in stages at high temperature with activated red mud and bentonite prior to blending with zeolites, to produce said heavy metal mediated biochar composite; the process significantly extends the migration time of heavy metals, increases the stability of h…
