英文摘要 | Batch and continuous co-treatment of two typical hazardous wastes via supercritical water oxidation technology (SCWO) was investigated, that is, oil-based drill cuttings (OBDC) from a shale gas field and high-nickel-content electroplating sludge (Ni-EPS) from an electroplating factory. OBDC, an extreme representative of hazardous waste rich in organic materials, acts as an auxiliary fuel that provides heat from exothermic reactions during SCWO. The average reaction temperature in the continuous reactor increased from 378 degrees C to 495 degrees C. Ni-EPS, an extreme representative of hazardous waste rich in metals, acts as both a diluent and a catalyst. Metals in the NiEPS tend to form NiFe2O4, ZnFe2O4, and NiCr2O4 after SCWO treatment, and when OBDCs are present, they are transformed into metal oxides (MOx). All the metal oxides are in the form of nanoparticles and exhibit catalytic activity. Owing to the synergistic effect of high temperature and in-situ formation of nanocatalyst materials, the total organic carbon (TOC) in the effluents was as low as 8 mg L-1, and the TOC removal efficiency (CRE) reached as high as 99.96%. This study provides an alternative process for the efficient and complete treatment |
