摘要：
The residual sludge generated from steel wastewater treatment is abundant in iron resource and its recycling has attracted widespread attention. In this study, a novel iron-rich biochar (FSB) with acceptable environmental risk was developed by one-step pyrolysis using steel sludge as raw material, and its adsorption-reduction efficiency and column experiments for hexavalent chromium [Cr(VI)] were determined. The results showed that pyrolysis can effectively reduce the potential environmental risk of iron-rich sludge and effectively enrich iron ...
